SYNCHRONOUS TRANSMISSION SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a synchronous transmission system in which the latency of data transfer is reduced and a transmission band is improved.

SOLUTION: The synchronous transmission system is constituted of connecting a CPU to a memory through transmission lines 30-35. A clock signal S101 on the CPU side becomes a signal S107 by changing its duty ratio by a duty adjustment circuit 20 and the signal S107 is transmitted through the transmission line 30 and received by the memory side as a signal S111. The duty adjustment circuit 20 can change the duty ratio in accordance with a adjustment signal S200. The adjustment signal S200 is generated on the basis of signal transmission time from the CPU to the memory, signal transmission time from the memory to the CPU and processing time from the input of a data signal to the memory up to its output.
