This repository contains a simple implementation of the 32 bit RISC out of order processor.

The proposed algorithm was developed under Debian Linux 64bit operating system(version 11.6), with the following toolchains:

Locate the root source code, then type the folowing:

$ make clean
$ make -j4

If the compilation process proceeds successfully, you will see "unext_sim" binary under build directory.

UnextSim CPU simulator
./unext_sim -file [-debug] [-pc]
where:
        -file           [required]      Input binary file.
        -pc             [optinal ]      Input binary file, integer >=0, default(0).
        -instruction    [optinal ]      Instruction count >=0, default(0). If =0 execute all instrucitons.
        -debug          [optinal ]      Show debugging info, defualt(false)

$ build/unext_sim -file app/test.bin

Locate the root source code, then type the folowing:

$ make unittest
$ ./build/unittest

Note: The unittest is based on Google gtest.
