Abstract
PURPOSE: To reduce the number of parity circuits and to simplify the system constitution, by providing a parity circuit with the CPU of system performing the transmission and reception of direct data between the memory device and the direct memory access device.
CONSTITUTION: The transmission and reception of data is directly made between the memory units 2, 3 and direct memory access devices 4, 5 via a bidirectional data bus 6 under the control of a CPU1. A parity check circuit PC11 and 1 or a parity bit generating circuit 12 are provided in CPU1 of this information processing system. The parity check of transfer data transferred on the bus 6 is made at the circuit PC11, the circuit PC12 produces the parity bit to the transferred data, simplifying the system constitution through the reduction of the parity circuit of system.
