Error module in rigor environment anti-irradiation high speed communication chip IP core

Abstract

The invention relates to an error module in an IP core of an antiradiation high-speed communication chip in a severe environment. The error module comprises two submodules which are an error declaration module and an error handshake module respectively, wherein the error declaration module is used for detecting that whether an error occurs and the generated error is a parity error, a disconnection error or a credit error; error report signals outputted by the error declaration module can also have different signal value outputs according to different conditions of input signals; the error handshake module adopts a finite state machine to comprehensively analyze various generated errors, switch between different states, and judge whether the errors are effective and whether the errors are read out; and the finite state machine in the error handshake module has four states which are waiting errors, reporting errors, reading out errors and waiting release respectively.

Description

(1) Technical field: [0001] The invention discloses an error module in an IP core of a harsh environment anti-irradiation high-speed communication chip, and the error module is used for correspondingly processing various errors occurring in a link. It belongs to the field of communication technology. (two) background technology: [0002] Embedded systems for harsh environments generally refer to unattended monitoring and control systems that can be loaded on satellites, aircraft or on the ground (open air, mines and other harsh or dangerous environments). The monitoring function is used to obtain the dynamic change information of the space, time and frequency spectrum of the target to be measured in real time, obtain the statistical distribution of the target to be measured and predict the probability of its mutation, and the control system will also implement corresponding control on the system according to the measurement results. In order to adapt to the working conditio...

Problems solved by technology

[0007] Foreign countries are also developing anti-radiation high-speed communication SOC single-chip, but the chip is integrated with a single-chip microcomputer. Since the single-chip microcomputer is an IP (Intelligent Propriety) hard core, the system structure is not changeable, so this solution has poor flexibility and high price

[0008] ●The country is also developing towards SOC single chip, and there is no product yet, nor has it been put into use
