Inter-processor communication using Mcbsp: one frame has more words

Other Parts Discussed in Thread: CONTROLSUITE

Hi all,

I have some questions about the inter-processor communication using Mcbsp. In my project, Mcbsp on one DSP works as a master; the Mcbsp on another DSP works works as a slave. For each frame, I plan to use multiple words (e.g., 4 words) and each word is 32 bits.

If each frame only has one word, on the slave side, I can use "receiver data ready register" to decide to read the received data. But if each frame has more than one words, the entire bit stream in the frame is contiguous. How can I read the data on the slave side?

Thanks

Fei
