The agenda for the TriMedia User Group meeting in April is being filled in. Some recent highlights in the 'Roadmap' sessions: details of evolution of the...
Dear : I have a FFT testing program run in LCP-1500, which yields 100 FFTs in 12 seconds. Sample size in each FFT is 2048. Yes, this FFT is not fine- coded for...
Sounds too slow. I think Trimedia should be able to do 100s of FFTs in a second if not 1000s. For relatively accurate figure you can compute the number of...
By this calculation, obviously my FFT testing program requires great improving. Is there existing FFT sample/utility source code for TriMedia to have better...
I tried a 2048 point FFT using a textbook FFT implementation (from Paul Embree's book 'C language programming for DSP'. Compiled for a tm3260 this ran in 277 k...
Dear Eric, Unfortunately, I don't think there is one freely available for Trimedia. However, there is sufficient literature available to learn to carry out the...
... in ... fine- ... info ... Hi, There is a free FFT library called FFTW that is able to generate C sources for FFT algorithms. Information can be found on...
A point to ponder for Trimedia Community -- everybody is re-inventing the wheel. You can easily obtain such algos for PC, Texas Instuments, ... but not for...
There is also a simple FFT implementation in C at http://cag.csail.mit.edu/streamit/apps/benchmarks/fft/c/fft2/fft.c Complete application in simple C that will...
If you ask on TCSHelp, I can give you the link to a package of optimized FFT's. If some of you experts are willing to review it, maybe we can declare it ready...
I would have loved to review it, if I was working on FFTs these days; or I had more hours in a day ;-) Somebody has to post something to the public under the...
Hi Ahmad, I understand your frustrations. I would like to clarify a few things: TI is ahead in many respects compared to PNX1500 and PNX1700. BUT: A 1GHz C64...
Hello all, I got the material from Chuck and Tom and will now do some own investigations. Results will be shown in a presentation "FFT on TriMedia" at the...
Here are some info I got again on LCP-1500 by the efforts of Dr. Cho. It's interesting. 1. The performance I got with my FFT program (not TriMedia-tuned), was ...
Dear Torsten, Lets talk video, have a look at the benchmarks (these contain audio/video benchmarks, ALONG WITH THE SAMPLE CODE WHICH ACHIEVES THIS): ...
I'd like to evaluate quantitatively the efficiencies resulting from the TSSA1 software component architecture. One goal of the component architecture is to...
I am having a serious problem with calling tmmlMallocAlign after having generated an out of memory failure once. Regardless of the amount of free memory and...
I have discovered a couple extra points to add to the problem description: 1) the printf hack only works in a trace build, it does not work in retail. 2) the...
dear all: I use tmfat32 , there is not any probems when write files solely, there is not any probems when read files solely. when i use two tasks, the one...
Hello,all I'm now writing a WLAN NIC(PCI) driver under TM1300+pSOS, the NIC's chipset is AR5212, which belongs to Atheros company. Generally, there are two...
Can't be sure, but this sounds like another problem that came up recently. You can request the patch on TCSHelp... Chuck Peplinski TriMedia Tech Support for...
Do you have the old DVE-2 development system from MDS? The software comes with it has some useful examples. Best Regards, Alfred Lee ... From: "alzner_2000"...
tmFat32 has no notion of file (process, task) ownership so if one tasks writes to a file and another reads from the same file at the same time this (probably)...
thank you i use "fread" read files , i use "fwrite" write files, i write and read the different files, i test that there is no any problem writing and reading...
Sorry, I don't have any examples except some documents, could you give me some examples, or tell me how to implement memory-map in pSOS to access external...
Sorry, but I don't understand your scenario. Can you provide pseudo-code to describe what you're doing? E.g., task 1 start, and the does what, task 2 starts...
I found a file by this name: TMApps\INCLUDE\TM1\tmPCI.h See if you can find it in your installation. Or else I'll have to dig up my old archive. That may...
