HANDSHAKE PROTOCOL CONVERSION LOGIC CIRCUIT AND INPUT/ OUTPUT INTERFACE CIRCUIT FOR ASYNCHRONOUS LSI CHIP

摘要

PROBLEM TO BE SOLVED: To reduce the time required for one time data transfer to the half at maximum.;SOLUTION: In this input/output interface circuit for an LSI chip for packaging a 4-cycle bundle data transfer system asynchronous circuit, at the time of outputting data to the outside of the chip, a handshake protocol is converted from 4-cycle to 2-cycle by a logic circuit 130, and at inputting data from the outside of the chip, the handshake protocol is converted from 2 cycle to 4 cycle by a logic circuit 140.;COPYRIGHT: (C)2003,JPO
