Abstract: An apparatus and method processes data in series or in parallel. Each of the processors operating may perform arithmetic-type functions, logic functions and bit manipulation functions. The processors can operate under control of a stored program, which configures each processor before or during operation of the apparatus and method to perform a specific function or set of functions. The configuration of each processor allows each individual processor to optimize itself to perform the function or functions as directed by the stored program, while providing maximum flexibility of the apparatus to perform any function according to the needs of the stored program or other stored programs. Communication between processors is facilitated for example, via a memory under control of memory management. Communication between the processors and external devices is facilitated by the memory management and units capable of performing specialized or general interface functions.
