Memory timing is still not working well with Amiga custom registers. Seems to read ROM okay. RAM is hit-and-miss.
Right now, boot is hardwired. We need to save the various configuration states into EEPROM. - core type (68000/EC020/030) - FPU enabled or not - base CPU clock (1 to...
Some opcodes like BCD may require the stack (check) and if so, will need to be rewritten.
It might be a good idea to have something that can run all/most 68K opcodes and provide output.
Interrupt handling was removed when I pulled the old C interpreter out. Need to put that back in.
PRU code is still working with the Alpha pinout. Need to update and expand on the PRU functionality as per the beta.
Self explanatory. We're implementing the WHOLE 68882 opcode table, possibly the 68040 additions for single-precision as well. All 68030 opcodes should be included as well, but there is no real...
Need some example code on how to - execute ARM instructions - access EEPROM for settings - change base parameters (e.g., clock speed)
Accelerators can access chip RAM as fast as Agnus -- that is, perform a memory read/write per cycle. This isn't 100% compatible and needs to be a user option.
