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 3830d 02h /light52/
25 Pre-generated object code packages updated with new test bench. ja_rd 3830d 02h /light52/
24 Basic CPU test bench modified to catch previously undetected bug in CLR BIT. Still too weak though... ja_rd 3830d 02h /light52/
23 Fixed CLR.bit when ACC was the target.
Implemented solution suggested by Stephane Bouyat, worked like a charm!		 ja_rd 3830d 02h /light52/
22 Fixed comments in object code package generation script.
The comments were awfully wrong -- leftover from another project, actually.		 ja_rd 4121d 06h /light52/
21 ja_rd 4136d 10h /light52/
20 ja_rd 4136d 10h /light52/
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 4136d 10h /light52/
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 4136d 10h /light52/
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 4136d 10h /light52/
16 Test bench modified: now tests IRAM and SFR addresses when testing direct mode instructions (instead of only IRAM). ja_rd 4138d 07h /light52/
15 Test bench modified: now tests IRAM and SFR addresses when testing direct mode instructions (instead of only IRAM). ja_rd 4142d 05h /light52/
14 BUG FIX: <DJNZ dir, rel> didn't work when addressing an SFR.
Signal direct_addressing fixed.		 ja_rd 4142d 10h /light52/
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 4142d 10h /light52/
12 BUG FIX: The build script did not configure XDATA space properly.
XDATA size was zero, which made the HW tests fail.		 ja_rd 4142d 13h /light52/
11 Removed old 'demos' directory. These files are now in the 'boards' directory. ja_rd 4204d 12h /light52/
10 Updated 'quickstart' to reflect new organization of demo directory. ja_rd 4204d 12h /light52/
9 Fixed quartus-2 project file -- replaced absolute output path with relative path. ja_rd 4204d 13h /light52/
8 Added support to build demos on another board: Avnet's Spartan-3A Evaluation Board. ja_rd 4207d 04h /light52/
7 Removed obsolete comment from core include file. ja_rd 4207d 05h /light52/
