Abstract
This project aims to construct an 8-bit computer architecture in a subset of MIPS. With a subset of MIPS ISA, an 8-bit processor was designed using Verilog language. Each instruction is set to 1-byte, or 8-bit, length, and the main memory is word addressable while the instruction memory is byte addressable. There are 4 addressable registers: $s1 (00), $s2 (01), $sp (10) and $ra (11). Two other registers in the register file, slt_0 and slt_1, cannot be addressed directly, but may be well utilized for jumping (beq instruction). All registers are initialized at 0, while the $sp pointer is initialized at 0xFF (255 in decimal), which is the top of the memory stack.
Instructions (for the files in 'final' folder)
*you need Icarus Verilog (to run), and GTKWave installed (for wave form)
We have two files: either "mult.s" or "add.s" to compile and run (1), and show waveform using gtkwave simulator(2):
(1) make asm //input file: either "mult.s" or "add.s"
make run
(2) make wave
