Abstract
PURPOSE:To transfer data between processors at a high speed with use of simple hardware by using a 1-bit hardware flag which is controlled by one of two processors and switching a bus between the processor and a shared memory according to the state of said flag. CONSTITUTION:The transceivers 5 and 6 having three different states are switched by the output of a flip-flop which is controlled by a slave microprocessor (MPU) 2. Then, a shared memory 4 is selectively connected to a master processor MPU 1 or the MPU 2. Thus a proper access is possible to the memory 4 from the MPU 1 or the MPU 2. Then the data can be transferred between both MPUs via the memory 4. As a result, the data are transferred at a high speed between both processors 1 and 2 via a simple circuit.
