This week my primary focus on the programs that will be run on the AGC and finishing up the first revision of the PCB. I have been analyzing sample AGC assembly routines and experimenting with certain basic instructions (such as XCHG, MUL, DV, etc.) to get a feel for how to develop code for our implementation. I have also identified certain subroutines used by the actual Apollo missions that we will be able to run on our architecture with minimal to no changes. This will be a nice demonstration of the correctness of our implementation. Finally, I have more or less finalized the first revision of the board. Next week, I will triple check my schematics and layout and get ready to send the gerber files out to be fabricated. Also, I will continue experimenting with the AGC Assembly language to build some proof-of-concept programs.
