Hello, I have been using 5509A to send data out of the device, using the provided example code from Spectrum digital, there is no problem in this part, but now i need to receive data from the PC. I have tried to run the system in loopback mode, but noticed that the input buffer of the DSP remains unchanged even after i send OUT data from the host PC. Please find below the functions...

Hi,everyone the TI documents illustrate that two DMA controller can't access the same port simultaneously,and the port defined as DARAM SARAM EMIF peripheral. so if I implement a program in DARAM spaces use two DMA ????one for read ,anther for write,then their can't work simultaneously in one clock cycle. Could anyone who know about this tell me if my understanding is right? Could CPU and DMA ...

Dear All; I have bought DSK5510A and now I want to use aic23 codec without DSP/BIOS. I converted "dsp_app1" to a DSP/BIOS less project. But it doesn't work. How can I start codec in my code; Is it enough to open it by codec_open from BSL library? I set and open MCBSP1 and 2 and DMA channels based on dsp_app1 but I don't know how can I configure and start data transferring by MCBSP2. Would you...

HI all, I am using TMS320C55x DSPLIB Release Version 2.40.00, I have modified the function MUL32 into MUL16, now i want to modify the function (mul.asm) for fractional point multipication, so how can i do that? does any one have any document for fraction number multiplication in fixed point dsp c55x. Thanks in advance, Rahul Jadhav.

Hi all, i am using TMS320C55x DSPLIB Release Version 2.40.00 , when i trie d to implement some functions like 1)mul32() 2)sqrt_16 3)add() 4)power() from the library and i am not able to trace out the results. In case of mul32(): As it is implemnted for single MAC (17x17 bits), it has to choose 17 bits from long datatype(32 bit) for multiplication, whether it does any other proc...

Hi every one, I used the dma4 project from examples\evm5510 folder for 5510 simulator. it built and compiled properly but it could not transfer xmt buffer to rcv buffer by dma. and the interrupt service routin of dma is not run. I also tested the dma3 project but it does not work too. could you help me how cn I solve this problem? Regards
