Instruction decoder verilog
Nettet3. apr. 2016 · You already have an adder used for you PC = PC + 1 operation, it would be really nice to re-use this adder for branching. This adder must be placed somewhere in front of your PC-register. What to add must be decided by your circuit. Your program counter must be able to: load immediate from instruction word or add branch value or … Nettet18. mar. 2016 · I have implemented a 4x16 Decoder using Verilog along with it's test. For each case the decoder should output a 16-bit digit with only one of the bits high. I can't manage to get all the desired outputs when I run the program. Here is the code for the Decoder and test, and the output at the console: 4x16 Decoder:

If you take an add operation C = A + B, to do this we will need to dedicate 9 bits of our 16 just to addressing registers – so it’s quite a lot. The core operations we want from our CPU are basic integer operations and other functions such as compare and memory manipulation. Operation.
