IDE: CodeBlock(C++)
1.Purpose: To have a basic understanding in Central Processing Unit (CPU) by designing a preliminary CPU.
2.Specification of CPU: (1) 8-bit address (2) 4 general purpose registers and 1 program counter (all 8-bit) (3) Single-cycle (1 instruction is resolved in 1 cycle)
3.Instruction Set Architecture (ISA): imm is short for immediate, Sel is short for select, Addr is short for address. See Note.jpg for detailed explanation of every instruction.
4.I/O Specification: (1) CPU should be compiled as executable file and read a file called input.txt without asking users to input the file’s name. (2) input.txt contains the instructions being executed in binary format with no mark. (3) CPU should output a file called output.txt after it finishes all operations. (4) output.txt contains the content of data memory, registers and program counter in binary and decimal (2’s complement except program counter).
