How to enforce a static stream to be implemented using LUTRAM

Hi,
My design has a lot of internal static stream variables and most of them are with depth 4 to 16. However, I found that in the HDL generated by HLS, all the FIFOs are forced to be implemented with block ram. I tried to use
#pragma HLS RESOURCE variable=fs2fgFixMsg core=RAM_2P_LUTRAM
and
#pragma HLS RESOURCE variable=fs2fgFixMsg core=FIFO_LUTRAM
but that doesn't make any difference. Is there any way to force it or hopefully set a threshold value so that any depth less than that will be implemented with LUTRAM? Any help will be highly appreciated.
Best Regards,
Jimmy

just realized I am putting the pragma to the wrong fifos, problem solved. Sorry for that.

How advantages of "Call By Reference" can be implemented using Java

As I know that java doesnot support "Call By Reference" as C++
does.
I want to know that how advantages of Call by Reference can be
implemented using Java.

There is some misunderstanding here. Method arguments in Java are passed by value. However, if you pass a reference (to an object) by value, you can still modify the object that the (copy of the) reference points to.
public void method1() {
StringBuffer buf = new StringBuffer();
// Here, method2 cannot change the value of the variable buf,
// but it can modify the object that buf points to.
method2(buf);
public void method2(StringBuffer sb) {
// You can modify the StringBuffer.
sb.append("hello");
// But this is useless, it will not change the variable buf
// in the calling method.
sb = new StringBuffer();

How can I get netflix streaming audio, the video is fine but the audio coming through is from the TV(dish)

how can I get netflix streaming audio, the video is fine but the audio coming through is from the TV(dish)

It's exactly as I stated. Whenever I try to drag these kinds of loops (ESX24 / software instrument loops? the ones marked in green with the white music note next to them) from the loop browser into the timeline a message comes up saying Audio Not Found for that loop. And a new track is created automatically when loops are dragged into the timeline, so I'm not creating some other random / synth instrument track so I'm not sure what the deal is... But perhaps I'll try creating a software instrument track first and then drag the loop into that track and see what happens - maybe there's something with the default settings that automatically creates audio tracks whenever loops are imported?

How to setup a static IP for a wireless printer

This problem has been ongoing for several versions of OS X and the last five printers I've had and I'm finally over messing with it. For some reson, when using a wireless printer with OS X this is a repetetive problem, and I think if I configured the printer to a static IP address instead of using DHCP, it might work better. At least once a week, if not more often, I'll print something and get the ubiquitous Dock error of "Printer is not connected". The printer is still in Preferences, but if I delete it, then it doesn't show up as it should for selection.
The only way to fix this is reboot, and then the printer shows up again in Preferences. I select it and all is well again...until a few days pass and the same thing happens again. Using an HP LaserJet P1102w, still a current model, but it doesn't matter which printer I use. I also have an Epson Artisan 725 and the same thing happens with it about once a week. Also, this happens from both my Mac and my wife's Mac, so it's not an issue with just my machine.
I've searched for documentation on how to setup a static IP address for a wireless printer with the Airport Extreme, but all I find are tutorials on how to do it with an ethernet hard-wired printer. Any help would be greatly appreciated.

You could set up your router to do manual assignment of IP address instead of using DHCP, but that is a PITA, because then you'd have to manually set up IP for all your devices.
If you have AirPOrt Extreme, you could do this:
In your Apple TV, go to the Settings >> About and write down the MAC address of your ATV
Start up the AiPort Admin Utility
Go to Network tab
click + in the DHCP reservations
Choose an IP you want for your ATV & Enter the MAC address
From now on, this IP address will be reserved to the MAC address and only your ATV will be able to get it, no other device will.
It is not a static IP in a true sense, but behaves just like one.
Works great for me...
If you don't have a AP Extreme, I'm sure other routers will allow you do reservations too.

How to setup a static multicast ARP entry with Cisco SF300-08?

We're running a cluster in multicast mode as a loadbalancer.
We have Cisco SF300-08 and when we adding a static ARP entry results in an error message telling the user that the hardware address needs to be a valid unicast MAC address.
So how to setup a static multicast in Cisco SF300 or maybe someone know other solution to setup multicastes mode in Cisco SF300.

Hi, Tom!
We have two watchguard xtm505(cluster active-active) in our network. Watchguard interfaces have one ip and one mac adresses. IP 192.168.111.1(Unicast) and MAC 01:00:5e:02:02:03(multicast). Cisco SF300 is router to outside networks(to internet). Cisco IP adresss is 192.168.111.254. There are another some hosts in this network.
Ping from hosts to 192.168.111.254 works well. Ping from hosts to 192.168.111.1 works well too. But there is no ping from watchguard cluster(192.168.111.1) to Cisco(192.168.111.254). And there is no routing to internet
This is well-known situation. We need to do following(example for cisco 3750):
1.    Start the Cisco 3750 command line interface.
2.    Add a static ARP entry for the multicast MAC address of the FireCluster interface.
Type this command:
arp arpa
For this example, type:
arp 192.168.111.1 01:00:5e:02:02:03 arpa
3.    Add an entry to the MAC address table.
Type this command:
mac-address-table static vlan interface <#>
For this example, type:
mac-address-table static 01:00:5e:02:02:03 vlan 1 interface gi1/0/11
But we can't add arp entry on Cisco SF300. CLI tells us "MAC address illegal"!
We tried enable igmp snooping, but is not helps.
Could you tell more detailed about MAC groups?

Use INDEX hint to force Optimizer to use the specfied index.
You really need to investigate why Optimizer doesn't choose the index. Remember, INDEX SCAN are not always GOOD.

Hi Roger,
Thanks for your reply and my apologies for taking longer than hoped to respond. The problem I'm having is that the cover art shows on my iPad (e.g. for "Meet the Press", a weekly American news programme), but it doesn't in either iTunes on my Mac or (consequently) my iPod Nano.
I'm not sure I understand why the image, if it's embedded, would appear on one device but not on another for iTunes?
I tried going to the iTunes store and dragging the cover art across to iTunes on my Mac, but it only brings the link across (rather than the image).
Any help you could provide would be most appreciated!
Thanks and best regards,
Tony

How to enforce index

Hi Guys,
How to enforce index ?
Say for example,
select max(dt) from emp
emp table has an index called 'id1'.
I want to enforce this index for the above query. How ?
Inputs are welcome !

Your index on ID is worthless for this query.
You would have to add an index on your DT column. Even then, the index will only be used if you have a NOT NULL constraint on the column (or add "and dt is not null" to your query):
SQL> explain plan for
2 select min(dt), max(dt) from emp;
Explained.
| Id | Operation            | Name       | Rows | Bytes | Cost |
|   0 | SELECT STATEMENT     |             |     1 |     8 |   194 |
|   1 | SORT AGGREGATE      |             |     1 |     8 |       |
|   2 |   TABLE ACCESS FULL | EMP         | 91000 |   710K|   194 |
SQL> alter table emp modify (dt not null);
Table altered.
SQL> explain plan for
2 select min(dt), max(dt) from emp;
Explained.
| Id | Operation             | Name       | Rows | Bytes | Cost |
|   0 | SELECT STATEMENT      |             |     1 |     8 |    39 |
|   1 | SORT AGGREGATE       |             |     1 |     8 |       |
|   2 |   INDEX FAST FULL SCAN| EMP_DT      | 91000 |   710K|    39 |
---------------------------------------------------------------------Still, even without an index a full table scan of 91000 rows takes < 1 second even on my laptop. How are you getting 21 seconds?

How to enforce the message "Do you want to save changes?"

Hello,
How to enforce the message "Do you want to save changes?" when the user attempts to close a form after checking a non-database item (check-box).
All the other database items in the block are not updateable and only viewable.
After checking the non database item check-box, if the user tries to commit, then the system is saving the changes and call the appropriate procedure on save.
But if the user tries to close the window without committing, the form is not showing the message "Do you want to save changes?" since the check-box is a non database item.
How to enforce the message "Do you want to save changes?" in this scenario when the user tries to close the window?
Thanks in advance.
Cheers
Sri

This is a fairly common question in the forum. You will need to override the default exit form process and check to see if the checkbox is checked. You can do this in the Key-Exit trigger. For Example:
DECLARE
al_id     ALERT;
al_button NUMBER;
BEGIN
IF ( CHECKBOX_CHECKED('YOUR_BLOCK.CHECKBOX_ITEM') ) THEN
     /* Display an Alert here that asks, "Do you want to save changes?" */
     ...code here to set the properties of your alert...
     al_button := Show_Alert(al_id);
     IF ( al_button = ALERT_BUTTON1 ) THEN
        --YES
        /* Perform COMMIT Processing here...*/
     ELSIF ( al_button = ALERT_BUTTON2 ) THEN
        --No
        Exit_Form(NO_VALIDATE);
     ELSE
        --Cancel
        RAISE Form_Trigger_Failure;
     END IF;
ELSE
     Exit_Form;
END IF;
END;If you need more help with the Alert, please check out the SHOW_ALERT topic in the Forms Help.
BTW, what happens if all the user does is check the checkbox? No other changes have occured. What changes are you trying to process?
Hope this helps,
Craig B-)

How to link a static library in java

Hi all
I would like add a static library (with an extension of ".a") to my java program
and use the rutines in it. I made a search on the Internet but could not find much.
The library created by compiling several fortran programs.
Does anyone know how to do this (linking & calling the subrutines)
Thanks

Thanks for the suggestion and for the tip again. I am doing what
you suggested (writing a C program to interface java with that static library
( ".a") ) But where in the C code do you specify and include that static library?This is mainly a linking issue. Suppose the FORTRAN API exposes the following
functions: FBQ001, FCQ042 and FDB005 (well, this is FORTRAN, so the names
should be silly ;-)
For the sake of simplicity, assume that these three routines don't take parameters
and don't return a value.
You could create a little Java class that could (indirectly) access those three
routines:public class FORTRANWrapper {
   public static native void FBQ001();
   public static native void FCQ042();
   public static native void FDB005();
   static {
      System.loadLibrary("wrapperlib");
}Note the little static block that loads your own wrapper lib. Read on:
use javah against this little class above. It'll generate a .h file containing the
prototypes of the three wrapper functions for your FORTRAN API.
Note the funky names generated by javah. Don't change them but create a
simple .c file with the implementation of those functions. These functions
should simply call the FORTRAN functions; check your manuals how to
call FORTRAN routines from C.
Finally, compile your .c file and link it against the static FORTRAN .a library.
Use the correct linker flags (system dependent stuff here) to create a
shared object (.so) file. This should generate your wrapperlib.so file,
loaded by the System.loadLibrary method (see above).
kind regards,
Jos
