Title
(EN) DEBUGGING PROTECTION SYSTEM AND DEBUGGING PROCESSING MODULE
(FR) SYSTÈME DE PROTECTION DE DÉBOGAGE ET MODULE DE TRAITEMENT DE DÉBOGAGE
(ZH) 一种调试保护系统及调试处理模块
Abstract
(EN) A debugging protection system and a debugging processing module (101). The debugging protection system comprises the debugging processing module (101), a debugging port (102), and a debugging switch group (103), wherein the debugging port (102) and the debugging switch group (103) are respectively connected to the debugging processing module (101). The system solves the problems of low security of a debugging channel and information leakage of other cores when debugging a certain core in a multi-core microprocessor.
(FR) L'invention concerne un système de protection de débogage et un module de traitement de débogage. Le système de protection de débogage comprend le module de traitement de débogage (101), un port de débogage (102) et un groupe de commutateurs de débogage (103), le port de débogage (102) et le groupe de commutateurs de débogage (103) étant respectivement connectés au module de traitement de débogage (101). Le système résout les problèmes de faible sécurité d'un canal de débogage et de fuite d'informations d'autres cœurs lors du débogage d'un certain cœur dans un microprocesseur multi-cœur.
(ZH) 一种调试保护系统及调试处理模块(101),调试保护系统包括:调试处理模块(101)、调试端口(102)和调试开关组(103),其中,所述调试端口(102)和所述调试开关组(103)分别与所述调试处理模块(101)连接。该系统解决针对多核微处理器中的某一内核进行调试时,调试通道安全性低,以及泄露其他内核信息的问题。
