Lesson 4 - Multi-Rate Systems
Rate Changing Functional Blocks
In addition to the straightforward “Up Sample” and “Down Sample” blocks, System Generator also provides rate
changing functional blocks; that is blocks that also perform a specific function. The Parallel to Serial block will up
sample, the Serial to Parallel block will down sample, the FIR Compiler, if using a resource-shared multiplier will
down sample and the TDM block will up sample.
