1. A method of performing an arbitrary permutation of a source sequence of bits in a programmable processor comprising the steps of:

  • a. defining an intermediate sequence of bits that said source sequence of bits is transformed into;

    b. determining a permutation instruction for transforming said source sequence of bits into said intermediate sequence of bits; and

    c. repeating steps a. and b. using said determined intermediate sequence of bits from step b. as said source sequence of bits in step a. until a desired sequence of bits is obtained, wherein the determined permutation instructions form a permutation instruction sequence.
