F18A source HDL
The scan line generation is currently tied to the pixel scan-out rate (pixel clock) and needs to be separated. This is to decouple the scan line pixel generation from the...
The MK2 has 512K or additional memory that needs to be worked into the design in a way that is compatible with the original VDP, avoids the new memory space...
MK2, add a TMDS pixel scan out for a 720x480p resolution. This should be done at the top module, and the VGA scan out for the original F18A also re-implemented...
Specific to the MK2, add an SPI interface in front of the parallel host interface. Allows easy access for modern microcontrollers and I/O constrained devices.
The GPU needs to be reworked to fix these problems: 1. Change from a logic-based control to a microcoded control as per the original TMS9900. 2. Change the ALU to...
