Hi everyone I am working on a PEP5416 device and am using a TI C5416 simulator. I am implementing an acoustic model which takes the sound input from the microphone, process it (filters) and provide the filtered output at headphone. My code is working on the simulator, its not giving any errors and I have debugged it step by step, its nowhere getting stuck. But when I try to run the code on the ...

Megha- Suggestions: 1) Comment out Preemphasis() for now, during debug. 2) Does FilterBufferBySamples() expect floating-point arguments? If so, you are passing pointer to fixed-point, which is going to be a problem. 3) Place counters in these two loops and find out how long they wait: long rx_wait = 0; long tx_wait = 0; while (!PEP5416_AIC23_read16(hCodec, &bufferrcv[i])...

Dear Jeff I did following things: First: Working long rx_wait = 0; long tx_wait = 0; while (!PEP5416_AIC23_read16(hCodec, &bufferrcv[i])) rx_wait++; while (!PEP5416_AIC23_write16(hCodec, bufferxmt)) tx_wait++ cfir(); and inside cfir() I just did copy paste (xmt=rcv). In that case rx_wait count is varying 0 to 57 and tx_wait is 0 Second: Not Working output is noise long rx_wait = 0; ...

Megha- > Secondly when I calculated the rx_wait and tx_wait without FilterBufferBySamples I > got a range of values (0-50) for rx_wait and 0 for tx_wait. For rx_wait it was > changing every time. And what if you just do this: long rx_wait; long tx_wait; int sample; rx_wait = 0; while (!PEP5416_AIC23_read16(hCodec, &sample)) rx_wait++; tx_wait = 0;

I am creating a new discussion group for teachers of signal processing. The goal is to bring together as many (D)SP teachers as possible so if they wish, they can exchange all kind of useful information, like for instance which book(s) they use to teach their class, their favorite web sites, matlab tutorials, labs, etc. I am requesting your help today to help me build a list of teachers th...

Hey Everyone I need help regarding proper memory allocation of internal and external memory. The problem is my code is too big. Its not fitting into the memory. My MP/MC is 0, DROM is 1, OVLY is 1 Following is memory map in my GEL file: GEL_MapAdd(0x80u,0,0x7F80u,1,1); /* DARAM */ GEL_MapAdd(0x08000u,0,0x8000u,1,1); /* External */ GEL_MapAdd(0x18000u,0,0x8000u,1,1); /* DARA...

Megha- > Should I change anything in > settings or something to enable the external memory. As per as I know we dont have > EMIF settings in C5416 as in c55x. Right? Not exactly. There are memory-related registers you have to set for 5416, such as wait-states, BSCR, etc. Question: what .gel file are you giving CCS prior to use when it first opens? The initial .gel file should be se
