ALUminium

Description

ALUminium is a CPLD/FPGA code for a 8bits arithmetic–logic unit, made for processor like GP8B.

The goal of this project is to have a powerful 8bits ALU without the need of an external clock. This design has been made for the XC2C256-VQ100 CPLD.

Available operation :

0x00 = Addition 0x01 = Substraction 0x02 = AND Bitwise 0x03 = OR Bitwise 0x04 = XOR Bitwise 0x05 = INV Bitwise 0x06 = AND Logical 0x07 = OR Logical 0x08 = XOR Logical 0x09 = INV Logical 0x0A = Shift to the left 0x0B = Shift to the right 0x0C = Strict bigger than 0x0D = Strict smaller than 0x0E = Bigger than 0x0F = Smaller than 0x10 = Equal 0x11 = Multiplication 0x12 = 2Complement 0x13 = Rotate 0x14 = Rotate to the left 0x15 = Rotate to the right 0x16 = Write to the accumulator left/right and return operation left 0x17 = Write to the accumulator left/right and return operation right 0x18 = Write to the operation left/right and return accumulator left 0x19 = Write to the operation left/right and return accumulator right 0xXX = 0x00
