hello everyone: My board is PNX1502,develop kit is NDK4.3. There is a MAX3222 chip on our board. I use the new patched UART(tmdlUartGpio,tmhwgpio,tmdlgpio from...
Can I please ask people to vote in the poll on venue and date for the next TriMedia User Group meeting? The poll is in this group's 'polls' area at: ...
Hi, 1) I am writing driver of a simple chip where I need to play in microseconds. I am using PNX1700 and I know that it works at 500MHz and is VLSI as well...
The API that I believe is appropriate for you is tsaClock. The tsaClock API (and its friend tmClock) allows you to share a HW timer. The OS timer goes off...
Can you explain your specific need and why? How accurate do you need? Are you using it for hardware control? One other possibility is: microsleep(1000) ;...
Hi everyone: My design is based pnx1501,ndk4.3,tcs4.51. When my board boots from flash at powerup,it cannot boot correctly sometimes.it is so strange because...
ya I am using for hardware control. Actualy I want to implement a simple driver by that or you may say some kind of very accurate timing waveform and what I...
ya, I feel you are right and your solution is Genuine,I will try that API as well. 1) But infact, my need is not repetative, its just a simple protocol or...
Is gpio timestamp clock suitable? It can be used for waveform generation. Chris =========== Chris Bore BORES Signal Processing Www.bores.com ... From: "Fahad...
hi, I have a structure like: struct sth_hdr{ char a1; int a2; short a3; int a4; } I thought the sizeof it might be 11 bytes,but in the NDK system, the size of...
Dear hjzhang, The following code segment indicates that it is 11 when #pragma pack(1) is used. #pragma pack(1) typedef struct { char a1; int a2; short a3; int...
Since addsub on the 3260 core is only available in the single operation long variety, is there an efficient way to get the effective functionality of having a...
Hi, Following are three interesting implemenations of the DUADADDSUB funcationality. Each has relative advantage or disadvantage. For example, though...
Hi experts!I havs a problem about streamingSystem Resource fwrite.now I encounter some troubles but I dont kown where is worry!please tell me how to resolve...
Hi I am having some problem in identifying the problem with my code resulting in instruction cache misses.Often the over head is twice the CPU usage w/o ...
Hello there are useful strategies described in: NDK5.5\docs\Training\14_TriMedia_programmer_optimization_Aug06.ppt We have especially good experience with the...
I think your VideoProvider will probe the file to see if it can render it. If you provide an unknown file format the VideoProvider will refuse to render that...
1) keep your code small 2) use -tm5250_opt 3) use aggressive if-conversion (2) works because tm5250 stalls on the 4th cycle of each branch if the branch...
This sort of load distribution among I, I$, D$ is strange, however, I'd like to float a few comments. Firstly, the total load is 300MHz, indicating that you...
Thanx for the reply . Does frequent ISRs ,like ethernet , degrade the Instruction $ Best Regards ... From: Chris Bore To: trimedia@yahoogroups.com Sent:...
Dear Ahmad Well though the Processing Power consumption is low but it is not because the code size is small,it is because the statistics i mentioned are for...
Hi, let me come back to the partial linking proposal. I assume you know, where your code spends most of the time (hot spots like inner loops, ISR's etc.). run ...
Those would have to be very frequent and probably large ISRs. That behavior should show up with TimeDoctor - it shows ISRs. You might try generating a cache...
Good discussion. One thing I don't quite see stated yet: There are two reasons why "partial linking" helps. One is the use of the -tm3260_opt linker flag....
The topic seems to attract quite an interest. Therefore, I'd like to post some historical account of discussions on this topic dating back to 2003. Interested...
