# Byte-swapping

## Byte-swapping Mux

gate count for 4:1 MUX is estimated at 8 gates.  8x 64 gates for a total of 512 gates to provide aligned byteswapping 64 bit. (actually likely 5x64 for MUX part and 2x8 for selection part)

## Byte-swapping Pipe

per source and dest operand, 512 gates required.  if two source operands (ALU pipeline, Logical pipeline) this totals 1600 gates (per Function Unit).  3 operands (madd) is 2000 gates.  for an estimated 50 Function Units this totals around 100,000 gates.
