4.4. Dsptools
Dsptools is a Chisel library for writing custom signal processing hardware. Additionally, dsptools is useful for integrating custom signal processing hardware into an SoC (especially a Rocket-based SoC).
Some features:
Complex type
Typeclasses for writing polymorphic hardware generators * For example, write one FIR filter generator that works for real or complex inputs
Extensions to Chisel testers for fixed point and floating point types
A diplomatic implementation of AXI4-Stream
Models for verifying APB, AXI-4, and TileLink interfaces with chisel-testers
DSP building blocks
