<p>PURPOSE: To minimize read of a locked memory location and required participation in it in a multiprocessor. CONSTITUTION: For the purpose of minimizing required participation of an additional processor 22a in maintenance of consistency in the multi-processor and read/write of a loaded memory location, an extended processor buffer interface executes atomic fetch and summing operation and supports interleaved memory banks, which perform the operation of burst mode memory access at a rate of 400M bites, and includes a state machine, which can be switched so as to selectively provide a wait state required to support different memory access timings, and provides an improved serial interface for an external multi- element LED display device.</p> |
