Method and system for performing permutations using permutation instructions based on modified omega and flip stages
The present invention provides permutation instructions which can be used in software executed in a programmable processor for solving permutation problems in cryptography, multimedia and other applications. The permute instructions are based on an omega-flip network comprising at least two stages in which each stage can perform the function of either an omega network stage or a flip network stage. Intermediate sequences of bits are defined that an initial sequence of bits from a source register are transformed into. Each intermediate sequence of bits is used as input to a subsequent permutation instruction. Permutation instructions are determined for permuting the initial source sequence of bits into one or more intermediate sequence of bits until a desired sequence is obtained. The intermediate sequences of bits are determined by configuration bits. The permutation instructions form a permutation instruction sequence, of at least one instruction. At most 21 gr/m permutation instructions are used in the permutation instruction sequence, where r is the number of k-bit subwords to be permuted, and m is the number of network stages executed in one instruction. The permutation instructions can be used to permute k-bit subwords packed into an n-bit word, where k can be 1, 2, . . . , or n bits, and k*r=n.

Method and system for performing permutations with bit permutation instructions
The present invention provides permutation instructions usable in a programmable processor for solving permutation problems in cryptography, multimedia and other applications. PPERM and PPERM3R instructions are defined to perform permutations by a sequence of instructions with each sequence specifying the position in the source for each bit in the destination. In the PPERM instruction bits in the destination register that change are updated and bits in the destination register that do not change are set to zero. In the PPERM3R instruction bits in the destination register that change are updated and bits in the destination register that do not change are copied from intermediate result of previous PPERM3R instructions. Both PPERM and PPERM3R instructions can individually do permutation with bit repetition. Both PPERM and PPERM3R instructions can individually do permutation of bits stored in more than one register. In an alternate embodiment, a GRP instruction is defined to perform permutations.
