Slave processor

Abstract

Abstract PURPOSE:To shorten a program loading time by providing a data buffer between an internal bus and a common bus, outputting an internal state onto a common bus via a status buffer and mapping the contents of a local memory over a common memory. CONSTITUTION:An internal bus 120 is connected to a common bus 121 via a data buffer 4 and an internal state is outputted onto a common bus 121 via a status buffer 5. A holding signal is produced so that a local CPU 1 is set by the reset signal of the bus 121 or a specific I/O instruction and then reset by another I/O instruction. Then the CPU 1 is held by said holding signal and the contents of a local memory 3 are mapped over a common memory 13.
