26 Changed the VHDL simulation logging code to match the SW simulator.
The JBC ACC.x instruction is a special case that needs a tiny hack...
Note this affects only the simulation test bench, not the RTL!		 ja_rd 3814d 23h /
25 Pre-generated object code packages updated with new test bench. ja_rd 3814d 23h /
24 Basic CPU test bench modified to catch previously undetected bug in CLR BIT. Still too weak though... ja_rd 3814d 23h /
23 Fixed CLR.bit when ACC was the target.
Implemented solution suggested by Stephane Bouyat, worked like a charm!		 ja_rd 3814d 23h /
22 Fixed comments in object code package generation script.
The comments were awfully wrong -- leftover from another project, actually.		 ja_rd 4106d 03h /
21 ja_rd 4121d 07h /
20 ja_rd 4121d 07h /
19 Refactor: interrupts made 100% compatible to original:
IRQ priority logic implemented as in original MCS51.
Register IP implemented.
Interrupt mini-testbench code updated accordingly.		 ja_rd 4121d 07h /
18 Refactor: interrupts made 100% compatible to original:
IRQ priority logic implemented as in original MCS51.
Register IP implemented.
Interrupt mini-testbench code updated accordingly.		 ja_rd 4121d 07h /
17 Refactor: interrupts made 100% compatible to original:
IRQ priority logic implemented as in original MCS51.
Register IP implemented.
Interrupt mini-testbench code updated accordingly.		 ja_rd 4121d 07h /
16 Test bench modified: now tests IRAM and SFR addresses when testing direct mode instructions (instead of only IRAM). ja_rd 4123d 04h /
15 Test bench modified: now tests IRAM and SFR addresses when testing direct mode instructions (instead of only IRAM). ja_rd 4127d 02h /
14 BUG FIX: <DJNZ dir, rel> didn't work when addressing an SFR.
Signal direct_addressing fixed.		 ja_rd 4127d 07h /
13 BUG FIX: <DJNZ dir, rel> was tested only with IRAM addresses.
Now it's tested with an SFR too.
The test package has been fixed too with a XRAM configuration suitable for the test bench (it was zero).		 ja_rd 4127d 07h /
12 BUG FIX: The build script did not configure XDATA space properly.
XDATA size was zero, which made the HW tests fail.		 ja_rd 4127d 10h /
11 Removed old 'demos' directory. These files are now in the 'boards' directory. ja_rd 4189d 09h /
10 Updated 'quickstart' to reflect new organization of demo directory. ja_rd 4189d 09h /
9 Fixed quartus-2 project file -- replaced absolute output path with relative path. ja_rd 4189d 10h /
8 Added support to build demos on another board: Avnet's Spartan-3A Evaluation Board. ja_rd 4192d 01h /
7 Removed obsolete comment from core include file. ja_rd 4192d 02h /
