In this paper , using a top - down design scheme , the risc mcu ip core is divided into two parts : data path and control path . all the modules in the two parts are described by verilog hdl , a kind of hardware description language . the simulation and synthesis of the whole work are finished successfully with eda tools 本文对pic16c6x单片机系统结构、指令系统和系统时序进行了分析,并且在此基础上对精简指令集mcuip核进行顶层功能和结构的定义与划分,建立了一个可行有效的riscmcuip核模型本文将mcuip核划分为数据通道与控制通道两部分,采用asic设计中的高层次设计方法,使用硬件描述语言veriloghdl对这两部分的各功能模块进行了设计描述;利用多种eda工具对整个系统进行了仿真验证与综合。
After analyzing and comparing different partition rules , md32 pipeline architecture is finally defined , which meets the required instruction function , frequency and timing spec of md32 . a complete set of creative design method for risc / dsp md32 micro - architecture is presented , such as parallel design , internal pipeline , central control , etc . thanks to the adoption of these design methodology , control path and data path are separated , circuit delay is reduced , and complex instruction operations are balanced among multiple pipeline stages 它们将若干复杂指令操作均匀分配在几个流水节拍内完成,实现了任意窗口寻址等复杂指令操作,将整个处理器的数据通路与控制通路分离,减小了电路时延,从而满足了risc dsp不同指令功能和系统时钟频率的要求,构成了统一的、紧密联系的、协调的md32系统结构。
The mixed sensitivity problem is also researched in this thesis . the relation of the performance weighting function and the robust weighting function is analyzed . the effect of control path characteristic to system robust performance is taken as a new method to determine the locations of sensors and actuators 分析了混合灵敏度设计问题,阐明了性能加权函数和鲁棒加权函数的关系,以及控制通道特性对系统鲁棒性的影响,为传感器、致动器位置选择提供了新的依据。
Following describing the system ' s organisation , we discuss the design and implementation of the system in detail including data paths , alu . to design the control paths , we start with the analysis of mcs51 instruction set , and then discuss the instruction execution procedure instruction and operation , and schedule of instruction timing Risc51ipcore控制通路的重点是兼容mcs51单片机指令系统的设计与实现,本论文从mcs51指令系统的分析入手,详细讨论了指令的执行流程、内部指令和操作的设置、指令的时序安排的设计与实现。
