1. A computer system including a processor for performing matrix transform operations, comprising:

  • a single-ported RAM memory having memory cell locations for storing operands, said processor operable to store operands at memory cell locations of said RAM memory selected to permit retrieval of said operands in a desired sequence and collision free retrieval by said processor of pairs of said operands from identified ones of said memory cell locations during a single memory cycle, said processor further being operable to perform a matrix transform operation on said pair of retrieved operands to produce transformed values of said operands, and then to store said transformed values at the same memory cell locations at which the operands of said retrieved pair of operands were stored.
