Konstruktion av mjuk CPU i VHDL 2004 (svensk)Independent thesis Basic level (degree of Bachelor)Oppgave

Abstract [sv]

The task of this project is to implement a soft CPU-core defined in VHDL on a FPGA-circuit board. This is done in cooperation with CC-lab at the University of Halmstad to be used in the laboration course given in cojunction with the course Hardware construction using VHDL. One of the critical demands is to develop a CPU-core that is easy to understand and get an overview of. Therefore the processor is modularized where each module is easy to modify and this grants the capability to add new modules with new features. The CPU is implemented with a Harvard architecture and consists of those base components that are vital for the function of a processor capable of meeting the demands put upon it. The CPU is capable of executing instructions written in assembler. A set of instructions are defined and new instructions can be added. After concluding the test-phase and comparing the performance of the processor with a professionally constructed CPU, namely the MicroBlaze from Xilinx, one could draw the conclusion that our CPU is bulkier and performs less instructions per second but is on the other hand easier to comprehend with only a basic understanding of VHDL.
