A topdown design of an 8bit RISC MCU is presented, in order to overcome the limitation of MCS51 microcontroller The core is based on Harvard architecture with 16bit instruction length and 8bit data length The performance of the MCU has been greatly improved by introducing singleclockcycle instructions, setting multiple highspeed working registers, replacing microprogram with direct logic block, etc FPGA verification and computer simulation show that its maximum clock frequency and instruction e...

在对传统的MCS51系列单片微控制器的局限性进行分析的基础上，设计了一种基于增强8位RISC构架的微控制器内核。该MCU核采用哈佛结构、16位指令字长和8位数据字长，通过设计单周期指令、在内部设置多个快速寄存器及采用硬布线逻辑代替微程序控制的方法，加快了微处理器的速度，提高了指令的执行效率。计算机仿真验证和FPGA仿真验证的结果表明，该MCU的最高时钟频率和指令执行效率等指标均优于MCS51的5倍以上。

This paper applies Risk-based strategic-systems audit mode to build framework of enterprise materially misreport risk assessment. Advanced technology of computer auditing is used in diverse audit analysis procedure. In order to construct a scientific evaluating system, Case- Based Reasoning is also applied in this research to identify and estimate the risk factor more correctly in auditing. This system will achieve at debasement of audit risk by avoiding blind audit effectively, using audit resources reasonably and making pertinent audit program.

本文运用现代风险导向审计的理念，构建审计企业重大错报风险评估框架；先进的计算机审计技术应用于多样性的分析性复核中；基于案例的推理技术引入到审计风险评估研究中，建立一套科学的评估体系以便较为准确的识别、评估审计中的风险因素，以期达到有效避免盲目审计，合理分配审计资源，有针对性地执行审计程序，从而实现降低审计风险的目的。
