Correction circuit for error detection and correction technology

Abstract

The invention provides a correction circuit for an error detection and correction technology. The correction circuit comprises a pulse widening circuit module and a time sequence control circuit module, wherein the pulse widening circuit module is connected with a first signal output by an error detection circuit module of the circuit; when the first signal indicates that the circuit generates a time sequence error, the pulse widening circuit module captures the first signal and carrying out conversion to output a high-pulse width second signal; the time sequence control circuit module inputs a first clock signal of the circuit and the second signal, and generates a second clock signal which closes the first clock signal for a clock period through logic operation; when the circuit is verified, the time sequence control circuit module generates a reset signal and transmits the reset signal to the pulse widening circuit module so as to reset the pulse widening circuit module and close the second signal. The circuit is capable of decreasing the hardware overhead and reducing the working voltage and power consumption under the premise of effectively correcting time sequence errors.

Description

technical field [0001] The invention relates to the technical field of timing error correction of digital integrated circuits, in particular to a correction circuit for error detection and correction technology. Background technique [0002] With the scaling down of the size of integrated circuits and the development of low-voltage technology, variations in integrated circuits will occur due to reasons such as process, voltage, temperature, and aging, which will cause the timing of current integrated circuits to fluctuate accordingly. After the fluctuating signals are gradually accumulated through the registers at all levels, a timing error (TimingError) of the integrated circuit will be formed. Error detection and correction (Error Detection And Correction, EDAC) technology can detect errors in time when timing errors occur and Correcting the detected timing errors has gained wide application in the field of digital integrated circuits. [0003] The correction circuit is a...

Problems solved by technology

This process has a strict chronological order, but due to the delay of the signal passing through the wiring and the logic unit in the circuit and the transition time of the high-to-low level conversion of the signal itself, the moment the level value of the multi-channel signal changes, the output of the combinational logic It does not change at the same time, which often causes glitches in the GCLK signal, which causes competition and risk in the circuit, and increases the design complexity of the timing control circuit.

[0006] Therefore, it is urgent to design a correction circuit for error detection and correction technology to solve the problem that the hardware consumption of the correction circuit in the current EDAC technology is high, and when correcting timing errors, it is easy to cause glitches in the GCLK signal
