Hello Everybody, I wanted some info regarding ADSP2181 processor.I am working on FS1016(CELP). Is it possible to run this celp code on 2181.I tried but i couldnot get proper memory space? many suggested to run on blackfin.Moreover,I think this code is designed to work on Unix platforms,so is it possible to run on ADSP2181? I

Hai all guys The ADSP-2181 EZ-kit lite have 80KB of internal RAM , and preferably gives better performance and stability for assembly code with host connected (No Hangups !). But i feel some problem when i go for C- coding as it produces code that is bulker code. So i want to connect external RAM for the same. Maximum of h

Hello, I want to know if it is licit to connect an opn drain output from some device (W682510 voice codec by Winbond) to the RXD0 pin on serial port 0 of an ADSP-2181, and in affirmative case, which value to use for the pullup resistor. At the beginning I thought it was OK, but have not been able to make it work. DSP to codec is OK, I am generating a sinusoid from a table in the DS...
