    Package structure

    The chisel3 package presents the public API of Chisel. It contains the concrete core types UInt, SInt, Bool, FixedPoint, Clock, and Reg, the abstract types Bits, Aggregate, and Data, and the aggregate types Bundle and Vec.

    The Chisel package is a compatibility layer that attempts to provide chisel2 compatibility in chisel3.

    Utility objects and methods are found in the util package.

    The testers package defines the basic interface for chisel testers.

  1. object BarrelShifter

    A Barrel Shifter implementation for Vec type.

    A Barrel Shifter implementation for Vec type.

    Example:

    1. val input = 0xAABBCCDD.U(32.W)
val bytes = VecInit(input.asBools.grouped(8).map(VecInit(_).asUInt).toSeq)
val shamt = 1.U(2.W)
val output = BarrelShifter.leftRotate(bytes, shamt).asUInt // big endian
// output = 0xDDAABBCC.U(32.W)
// The depth of Mux is 2, whereas originally
// the depth of Mux is log(32) = 5
val output = BarrelShifter.leftRotate(bytes, shamt, 2).asUInt // depth is 1 now
