Abstract
PURPOSE: To ensure a quick check for the error bit by dividing the bit width of the data and then giving the parity to each divided bit width.
CONSTITUTION: The data featuring the 32-bit width on the data bus line and given from the main memory device is converted into the data of 16-bit width through information converter 500 and then sent out to the bus line to the CPU. Parity bit generators 901W904 generates one bit of parity with every 8 bits of the 32-bit width data and then sends it out onto the data bus line via NAND's 905W908. At the same time, the exclusive logic sum is obtained through gates 909W912 between the parity bit added to the information read out from the main memory device and the parity generated from generators 901W904, and thus the error is detected.
