Study And Design Of The SoC Platform Based On 8051 IP

The technology of SoC (System on a Chip) has been a important direction of IC design in21st century. The paper come from mentor's education department project "Research andDesign IC of the intelligent Information Appliance based on embedded SoC", and mainlystudy and design the SoC soft cores, and design a SoC platform based on 8051 IP. Theplatform verifies the 8051 IP and selects the Wishbone as the interconnection bus between IPcores and MCU. By accessing to the external RAM, it has realized the bridged interfacebetween 8051 and Wishbone by simulation its timing. Meanwhile, expand a external generalI/O port (P4). Design the common interfaces in household electric appliance, SPI, I~2C, PWM,and enhance the performance of 8051 IP. A SoC platform is created successfully, and awireless data acquisition system is built based on this platform.The platform is developed based on the QuartusⅡIntegrating Development Environment,adopt Modelsim 6.2b of MENTOR to simulate the soft cores. The electronic circuit andnetlists requested is obtained by the synthesis tool, Synplify pro 8.1. On the Altera's CycloneⅡDE2 development board, it expanded AT24C64 chip and PTR8000, and build a testplatform. Through verification, the cores work well and meet the command of system. Thewireless data acquisition system works well, too.The design of system adopts the means of Top-to-Down in front-end design andDown-to-Top in test, and RTL-level code is designed in HDL. The front-end design of I~2C,SPI and PWM soft cores has been completed.
