摘要
为减少在印制电路板(PCB)设计中的面积开销,介绍一种Flash结构的现场可编程门阵列(FPGA)器件,进而介绍采用该器件搭建基于先进精简指令集机器(ARM)的片上系统(SOC)电路的设计方法,该方法按照高级微控制器总线架构(AMBA),设计ARM7处理器微系统及其外设电路,通过用搭建的系统对片外存储器进行擦写,以及通过编写软硬件代码定制符合ARM7外围低速总线协议的用户逻辑外设,验证了系统的准确性,该系统可用于验证SOC设计系统。
In order to reduce area overhead in design of Printed Circuit Board,Introduct a field programmable gate array structure Flash device,And then introduce the design method that using this device build circuit that System-On-Chip based on Advanced RISC Machine.In accordance with the Advanced Microcontroller Bus Architecture,to design the ARM7 processor system and its peripheral circuit,through wipe external storage by this building system,and write hardware/software code to custom the user logic peripherals that accords with ARM7 Peripheral low speed Bus,verify the accuracy of the system,the system can be used to verify the SOC design system.
