ABSTRACT:
A new and improved shifter circuit for multiplexing bytes of data into various orders on a finite size bus is disclosed. The improved shifter circuit includes an array of barrel shifter circuits arranged into N groups of M shifter circuits per group wherein each shifter circuit has P data input terminals and P output terminals. The letters N, M and P represent integers. Each of the P output terminals of each of the M shifter circuits in a group are coupled to one another, respectively, so as to form N.times.P output terminals of the array.
