Multi-Rate Designs

Some designs implement kernels which are based on various data frame size. The data can be transferred through streams and/or windows. If you specify the --disable-multirate=true option in the aiecompiler command line, the repetition count must be specified for all kernels. The repetition count is the number of times a kernel is launched during one iteration of the graph:
repetition_count(k) = N;
This sets N as the repetition count for the kernel k that has a synchronous window connection.

For the kernel with an asynchronous window connection, the repetition count should be specified as follows:

async_repetition(K) = N
