After consulting with Steve, I have some great momentum again. Some of the more technical aspects of VHDL and digital logic are coming back to me and the structure of my descriptions are becoming more precise. I am almost ready to start describing the state machine that drives the ALU and register access. I am implementing a modified and abridged version of the MIPS operation set. So far, I have selected 34 basic operations that I would like to implement, and will try to get the mathematical ones up and running by week's end. The program operations - break, jump, etc. - will be next, and then we'll see about the memory access ones, like load word and such. I have enough registers at the moment that I needn't worry about write memory functions for the time being.
More to come soon.
