摘　　要：由于申威处理器维护、诊断、调试工具少,市面上很难找到灵活方便的调试手段。针对这些问题,我们创新的设计了一种调试器构想:它接受上位机调试指令,解析并转换为申威处理器能理解的指令格式,并通过Jtag调试接口,发送给申威处理器,然后获取申威处理器返回的数据或结果,重新封包后发送给上位机。此调试器可用于申威3A(421、421M、1621)、3B(831、3231)等处理器类型。Because there are few maintenance,diagnosis and debugging tools for sunway cpu,in fact,it is difficult to find flexible and convenient debugging means.In view of these problems,we creatively designed a debugging idea:the debugger accepts the debugging instructions from the upper computer,parses and converts the debugging instructions into the instruction format that can be understood by sunway CPU,and sends them to sunway cpu through JTAG debugging interface,then obtains the data or results returned by sunway cpu,and sends them to the upper computer after repacking.The debugger is used to sunway 3A(421,421M,1621),3B(831,3231)types cpu.
