Abstract

A method of interfacing a processor bus to a computation engine having a microprogrammable memory-centric controller and an array of memory, comprising the steps of providing a predetermined series of microcode instructions for execution by the MCC; selecting a start address within the series of microcode instructions for carrying out a corresponding operation; and executing the series of microcode instruction in the MCC beginning at the selected start address so as to carry out the corresponding operation in the engine. The present invention is useful in a wide variety of signal processing applications including programmable MPEG encode and decode, graphics, speech processing, image processing, array processors, etc. In telecommunications, the invention can be used, for example, for switching applications in which multiple I/O channels are operated simultaneously.
