Bitwise Operations

Project for CSC 343 - Computer Systems Design Lab with Professor Izidor Gertner at the City College of New York.

About The Project

• In this lab you will extend your knowledge of VHDL, ModelSim and Quartus by developing a circuit that performs bitwise operations, bit shifts and bit rotations.
• These operations are chosen by an OPCODE - a selector that determines which operation to perform at a given time.
• Please implement all 32 bit bitwise operation shown on “MIPS GREEN PAGES”, demonstrate on DE 2 board. E.g 32 bitwise “AND” operation.
• In addition, Implement conditional operation: Set Less Than -- SLT (signed comparison)
• Set result to 1 if a condition is true Otherwise, set to 0.
• Write a test-bench program to test all bitwise operation.
• Write a complete report including VHDL code, screenshots, and pics of demo on the DE2 board.
