This project contains a set of tools useful for DSP projects involving rocket-chip. In particular, it contains abstract classes and testers used in the CRAFT project for DSP blocks and chains. It also contains DSP junctions (our version of AXI4-Stream) and the SAM (streaming-to-AXI4 memory). The SAM is used at the end of a DSP chain to buffer data for readout by Rocket. Note this project depends on things like Chisel, FIRRTL, testchipip, and rocket-chip, so it does not compile or run by itself. See the dsp-framework and craft2-chip repositories for more information.
