|
|
-- Purpose : Implements two Xilinx RAMB16_S9 Block RAMs as one monitor ROM
|
| 10 |
|
|
-- initialized with a 4KByte version of the Sys09bug monitor program
|
| 11 |
|
|
-- for the System09 SoC. Sys09bug is based on the SBUG1.8 ROM
|
| 12 |
|
|
-- for the old SWTPc 6809 however it has been adapted to make use
|
| 13 |
|
|
-- of the features found on the Digilent Spartan 3 Starter board.
|
| 14 |
|
|
-- It includes drivers for a VGA VDU, PS/2 keyboard and serial port
|
| 15 |
|
|
-- and allows the user to examine and modify memory and load programs
|
| 16 |
|
|
-- over the serial port.
