splitSelectAdderAlgorithm4Bit static method

  1. @Deprecated('use splitSelectAdderAlgorithmNBit instead')
List<int> splitSelectAdderAlgorithm4Bit(
  1. int adderWidth
)

Adder block size computation algorithm. Generates 4 bit carry-select blocks with 1st entry width adjusted down. Return list of block sizes starting from the LSB connected one. adderWidth is a whole width of adder.

Implementation

  for (var i = 1; i < blockNb; ++i) {
