- Upon this platform , we designed software architecture , microcode data structure , and microcode process flows . after debugging , we take a carefully system test , and the results conform the design , and meet the requirements of real network applications
基于该硬件平台，根据本文提出的可堆叠式vlan方案，设计了网络处理器的软件系统构架、微码数据结构和微码处理流程；方案实现最终完成了硬件开发调试，软件编码和系统测试。 - And more than 70 % hardware are tested during microcode self - test since the execution of micro program can cover other data paths . boundary scan is designed according to ieee1149 . 1 , and some other instructions such as degug , runbist are provided to support internal fault testing , online debugging and built - in self - test besides the several necessary insructions . internal scan is implemented by partial scan , through this the boundary of logic component and user - cared system registers can be selected to be scanned
Bist用于测试cpu的微码rom ,其它ram则利用微码rom中的微程序进行测试,而微程序的运行则可以顺带覆盖其它数据通路,从而使高达70 %的硬件得到测试;边界扫描按ieee1149 . 1标准设计,除必备的几条边界扫描指令外,还提供了debug 、 runbist等指令以支持内部故障测试、在线调试及内建自测试;内部扫描采用部分扫描策略,选择逻辑部件的边界及用户关心的系统寄存器进行扫描,从而实现了硬件逻辑划分,方便了后续的测试码产生和故障模拟,并为在线调试打下了基础。 - Jx5 is a complex microprocessor , which contains cache , microcode rom , instruction prefetch unit , instruction decode unit , integer unit , mmx unit , floating point unit , page unit , bus unit , dp logic , apic and so on . it is very difficulty to test a such complicated microprocessor and receive anticipative fault coverage ratio . so , we must add dft in cpu ’ design

百科释义
Microcode is a layer of hardware-level instructions or data structures involved in the implementation of higher level machine code instructions in central processing units, and in the implementation of the internal logic of many channel controllers, disk controllers, network interface controllers, network processors, graphics processing units, and other hardware. It resides in special high-speed memory and translates machine instructions into sequences of detailed circuit-level operations.
