VarLEON: FPGA Based Processor Variability Emulator for Variation Aware Software
نویسندگان
چکیده
In the area of design automation, variability emulation is a powerful idea that can help bridge the gap between a conservative design and the opportunistic characteristics in a software. A variability emulator can be used to explicitly control hardware variability to study development of variation-aware software such as in Underdesigned and Opportunistic Computing (UnO) [1]. This project focuses on development of such an emulator comprising of both power and delay variability injection, on a LEON3 microprocessor. The implementation was realized on a Virtex-5 FPGA using Xilinx design tools. Keywords— Delay Variability, Power Variability, Variable Delay Element, LEON3, FPGA Editor, Kuhn-Munkres Algorithm, GRMON
