摘　　要：AOJCP(area-optimized JavaCard processor)是一种自主设计的基于微码、面积优化、低功耗的JavaCard硬件处理器.首先,描述了AOJCP中的微码处理器总体框架、单周期与控制-应答机制结合的微码设计、JavaCard指令执行过程;然后在FPGA(field programmable gate array)中实现.结果表明,AOJCP占用1410LogicCells(约合16k门),最高频率36.2MHz,典型时钟频率3.7MHz时,功耗为48mW.AOJCP is a microcode based, area-optimized, low power consumption JavaCard processor. The overall architecture of microcode processor, the microcode design unifying single-cycle and control-acknowledge mechanism and execution process of JavaCard instruction are discribed. The implementation result in FPGA（field programmable gate array） shows that AOJCP takes up 1 410 LogicCells（about 16 k gates）, that the highest estimated frequency is 36.2 MHz, and that the power consumption is 48 mW when it runs at 3.7 MHz.
