Title: State change detection system
Inventor: ITO KOJI
IPC: H04L29/00
Filed: 1994-02-18
Abstract: PURPOSE:To detect a state change accurately independently of a phase of an operating clock even when a delay is in dispersed on a parallel signal line by delaying a write timing so that the start-up of the operating clock is dissident during write cycle to a monitor buffer. CONSTITUTION:One set of parallel data being an object for state change detection are written to a monitor buffer 1 under the write control of a CPU. Then the data in the buffer 1 are sent to a state change detection circuit 2 operated by an operating clock asynchronously with the clock signal of the CPU via each signal line of a line 30 consisting of plural signal lines whose delay time differs from each other. The circuit 2 detects the state change of parallel data of one set at the start-up of the operating clock signal to detect the state change. When the operating clock starts up during write cycle to the buffer 1, the write timing is delayed so that the start-up of the operating clock is dissident with the write timing to the buffer 1.
