External Program Memory ignored when EA = 0
Information:
Type :: BUG
Status :: CLOSED
Assigned to ::
Arnim, Laeuger
Description:
Affected releases: 0.1 BETA
The external Program Memory is always ignored when EA = 0 with the t8048 system toplevel.
Desired behaviour is to access external Program Memory when code has to be fetched from an address location that is outside the internal Program Memory.
Fixed in t8048.vhd 1.3
Fix will be included in next release.

The main testbench (tb.vhd) has been updated to support internal and external ROM (both 2k size). In addition, the verification environment generates two hex-files. One for the internal ROM (t48_rom.hex) and one for the external ROM (t48_ext_rom.hex).
The above issue is now testable with the black_box/mb regression tests. |
