This week I worked with Adolfo to finalize the CPU so we could move towards getting the project onto the FPGA. At the beginning of the week, we had a self-tested CPU that covered a majority of the tasks and we had a working timer and memory. Throughout the week, we realized we had small issues with the memory so we redid that.
We were able to run Blargg’s test suites, one of our benchmark unit test suites. These tests extensively tested our CPU because they tested each possible instruction with every possible bit location and number. Currently, we are able to pass all the tests so we believe we have a solid and completed CPU.
Now we are moving toward putting everything on the FPGA. We have all the components that we need by using the Megafunction Wizard. Currently, I compiling it in Quartus and loaded the memory with one of Blargg’s test so we can test on the board rather than in simulation.
Goals for next week:
- Able to run Tetris on the FPGA
- Start working on the memory bank controller to support more games
