Hi group, I'm wondering what the most practical and modern choice is for coding 80 bits of data for a power-limited AWGN channel using BPSK, with the constraint that the encoder is a tiny device with just a few kbytes and a few MIPS. The decoder can be very complex. Suggestions appreciated. John

Hi, I was wondering if anyone could tell me what type of DSP i would need for a basic voice recognition system. The system would you a matched filter of 1000 samples and can have a sampling frequency of anywhere from 2200 toi 22050 Hz. Also the samples have a resolution of 16 bits. I'm confused on what sort of spec it would require e.g. in MIPS or MFLOPS. Any help would be very much apprie...

Hello, I was wondering if anyone could recommend a TI dsp chip for audio processing. I looked online but I could'nt find a chip that packaged an A/D, D/A, Flash, on-chip, while still having decent horsepower (100 mips or so). Motorola (Freescale) has something similar to what I want: the 56F8323. However for other reasons, my company does not want to use that chip. Any suggestions? Tha...

Hi! to expand on the subject briefly: I'm experimenting with mechanical television a la Baird televisor. I think it would be neat to encode three channels of color (YIQ) into one audio channel. I would like to use a fairly cheap microcontroller for demodulation because I have lots of experience with it (Atmel Atmega32). Thus far, SSB AM has been the most straightforward approach. On...

A/D Buffering on the TI TMS320F2812

Hi Folks, The 2812 has an on-board A/D converter, but it appears there is no DMA engine on this machine. Thus it appears that the buffering of samples from the A/D to internal memory must be performed on a sample-by-sample basis. Since this converter can operate as high as 12.5 MHz, this seems like it's going to eat 12.5 MIPS at a minimum just for this function at this A/D rate. Am I...

Is it true that TMS320C6416 has inbuilt function for FIR or is it that I have to write the whole C code (for FIR filter)on TMS320CXX as well. Any suggestions? Regards aamer

HEre is my question ... I have 20 acquistions to realise on a TMS320F28xx (100 Mips) The sample rate is 1khz. If i don t use the ADC of the TMS230F28xx , Is it possible to use 20 external ADC linked with the TMS320 with SPI ? But especially, is the GPIO Mux able to manage silmunatous input acquisition? Or do i have to use a time delay between 2 acquistions? Thank you
