I will be using an i2s codec with my 21065L, however I have some questions regarding the i2s protocol in the dsp. First, the dsp does not have any way to differentiate between the left and right channels received and/or transmitted, since an interrupt is gener

Hi there I working with the 21160 proccesor, and would like to initialize the codec(AD1881A) in assemble language. I can only find such program written in C. Does any of you have source code in assembler, or even better a core that set up the whole board like the traditional 21065L

Hi all! I'm a beginner with the Analog DSP's. I have a problem with the EZ- LAB kit. I would observe some signal through the expansion port on the platform, i.e. if I put in the universal register r0 the number 0xfffffff how I can and what have I to do to watch this signal on the

Hello Everyone, Well I have an interesting problem with my project. I have ported an Mp3 decoder to the SHARC and got it working on the 21065L, and 21060. The project is written in C and has one assembly function. In order to create enough storage space for my mp3 buffer I created a secondary heap which is in external memory. One both the 065L and the 060
