This week we sorted out and finalized what our new project will be due to moving to remote access classes only. We will continue with the original project idea of creating a FPGA Game Boy emulator, but we will no longer support audio due to the lack of access to the lab. We understand that integration will be especially challenging so we will rely even more on the unit test suites and those for the SoC. Additionally, we worked on the SOW to officially refocus the project.
I worked on implementing the datapath for the CPU. A majority of the datapath is coded and hooked up, but I will need to work with Adolfo to assure the signals are correct. Additionally, all of the FSM and signals have been finalized so now we will start integrating the components of the CPU and begin debugging once the decoder is finished.
Additionally, I started looking into “magic memory” that we can use to simulate our CPU before we have memory mapping completed. I looked at 18447 magic memory and 18341 P6. The 18341 P6 will be suffice because it meets our timing requirement and doesn’t require us using segments. To get this to work, we will need to alter the code to work with our CPU and create a .hex file to fake the memory.
My goals for this week:
- Finish coding the CPU
- Start testing the CPU with our version of “magic memory”
