CORDIC

Design and implement a flexible CORDIC generator in Chisel.

  1. Support vectoring and rotation modes
  2. Make widths for X, Y, and Z parameterized
  3. Gain correction will be optionally supported (controlled by a parameter). If gain correction is enabled, the output will be multiplied by the appropriate scaling factor. Otherwise, the unscaled result will be passed directly to the output.
  4. Z is modulo $2\pi$ with full range supported
  5. The degree of unrolling should be set by a parameter.

Parameters and IO

Cordic.scala defines some parameters objects, a Bundle to use as your IO, and an empty implementation of a FixedIterativeCordic (which you will need to implement).

CordicApp

The template also includes an App (similar to a main function in Java) that can be used to run your generator. It accepts commandline arguments. To see the options, run

sbt "run --help"

Tests

The template includes a simple test using DspTester and an associated ScalaTest specification. You can run tests with

sbt test
