JTAG abbr. 联合测试行动组(Joint Test Action Group);调试接口
- As an IEEE test standard,JTAG is accepted and used by many IC design companies and manufacturers.
JTAG作为测试标准已为芯片设计与制造厂商接受和应用。 - To improve data transmission rate of JTAG interface, instruction register and related control logic are redesigned.
为了提高JTAG接口的数据传输效率,指令寄存器和相关控制逻辑被重新设计。 - This design will implement the communication through USB or serial interface, including serial download based on STK500 agreement and JTAG ICE simulation.
本设计能够使用USB接口或者串口两种接口进行通信,包括STK500协议的串口下载与JTAG ICE仿真。
