ARM7

Implemetation of pipelined ARM7TDMI processor in Verilog.

See docs folder for datasheets and design documents of this processor. I have used 6-stage pipleline instead of suggested 3-stage pipeline.

A not-so-descriptive but useful report containing some design details is availble in 'Report' folder

DeepPipeline.v is the top module. It contains the controller and pipeline.

I tried to make the project as modular as possible. Still, pretty complex.

Modules

DeepPipeline.v - Top module containing controller

alu.v - ALU module

cond.v - Condition checker module

data_cache.v - Data cache module

instr_cache.v - Instruction cache module

instr_decode.v - Instruction decoder

mult.v - Multiplier Moduler

register.v - Register File

shifter.v - shifter module used for data processing instructions and some other instructions

tb.v - Test bench. Just contains clock ticktocking

Misc

I don't really have seperate 'memory' to keep things simple. I have data cache and instruction cache instead.

View all signals by running 'view.bat'

Currently, Machine code corresponding to 'fib.s' file is in instruction cache.

So, search for 'Write_enable', 'Write_address', 'Write_data' signals and view them to check for correctness of Fibonacci program.
