object PopCount extends PopCount$Intf
Returns the number of bits set (value is 1 or true) in the input signal.
- Source
- Bitwise.scala
PopCount(Seq(true.B, false.B, true.B, true.B)) // evaluates to 3.U PopCount(Seq(false.B, false.B, true.B, false.B)) // evaluates to 1.U PopCount("b1011".U) // evaluates to 3.U PopCount("b0010".U) // evaluates to 1.U PopCount(myUIntWire) // dynamic count

Package structure
The chisel3 package presents the public API of Chisel. It contains the concrete core types
UInt,SInt,Bool,Clock, andReg, the abstract typesBits,Aggregate, andData, and the aggregate typesBundleandVec.The Chisel package is a compatibility layer that attempts to provide chisel2 compatibility in chisel3.
Utility objects and methods are found in the
utilpackage.The
testerspackage defines the basic interface for chisel testers.
