Abstract:
The main purpose of this thesis is to integrate custom cores as peripherals
as Co-Processors (CPs) to a processor. For this purpose, a 32-bit open
source processor was be tested on an FPGA. For proof of concept, a simple
open source 8-bit processor was selected to run on FPGA using custom
instructions written in C. Thereafter, we tried to change speci cations and
peripherals of the peripherals like timers, UART, SPI etc. For 32-bit processor,
starting with an open source processor design for Leon 3, the study
involved synthesis of code, compilation of program, and test of pre-con gured
peripherals on an FPGA. Once a decent level of understanding was achieved,
a new peripheral was integrated into the processor to enhance the processor's
capabilities, and to adapt them for better performance in a given domain of
applications. Using study of processor architecture of Leon 3, we tried to design
our own processor with peripherals, memory management module and
custom compiler.
