設計了一款基于AVALON總線的8051MCU IP核。它支持MCS-51指令集，優化內部的結構，通過采用流水線技術、指令映射技術、指令預取技術、微代碼技術等極大的提高了IP核的工作速度，使IP核在100MHz時鐘下，能夠單周期執行一條指令。本設計使用Modelsim軟件完成了功能仿真和時序仿真，并在以Altera 公司的Cyclone II FPGA芯片為核心的DE2開發板上完成了硬件驗證。
AVALON Interface Specification,The AVALON interface specification is designed to accommodate peripheral development for the system-on-a-programmable-chip (SOPC) environment. The specification provides peripheral designers with a basis for describing the address-based read/write interface found on master and slave peripherals, such as microprocessors, memory, UART, timer, etc.
