Rev Log message Author Age Path
80 Improved usability of SoC (memory size calculation)
Added comments to SoC code.
Fixed starter kit board simulation test bench, added uart loopback
ja_rd 4414d 03h /light8080/trunk
79 DAA logic fixed and simplified ja_rd 4414d 03h /light8080/trunk
78 Fixed a number of errors in the last refactor of the VHDL side of the project:
- Path errors in the simulation scripts.
- The reset pin in the C2SB mini-test-bench was not being driven.
- The main vhdl test bench file was missing entirely.

All of these errors due to not properly verifying the commit...
ja_rd 4420d 04h /light8080/trunk
77 Fixed a few mistakes in the last code reorganization.
Mostly bad paths but also a broken comment in the UART source...

Added a mini-testbench for the VHDL SoC.
ja_rd 4431d 10h /light8080/trunk
73 New tool for VHDL object code constant generation.
Old VHDL template tool moved to tools directory.

ja_rd 4431d 10h /light8080/trunk
68 Corrected ihex2vlog tool to enable explicit RAM declaration for Spartan 2. motilito 4442d 05h /light8080/trunk
67 Corrected bugs in the Small-C compiler. motilito 4443d 08h /light8080/trunk
66 Adding interrupt example code to the Verilog implementation. An interrupt controller was added to the sample SOC module and a sample code was added to the "hello.c" example code. motilito 4458d 06h /light8080/trunk
65 Adding Verilog initial version to the svn.

motilito 4469d 13h /light8080/trunk
64 BUG FIX: Flags CY and AC were not clear by logic instructions
Added new flag to microcode: clr_acy
Used new flag to clear AC and CY flags unconditonally
Modified microcode for XR*, OR* and AN* to use new flag
Modified microcode assembler to support new flag
Addex explaination of new flag to documentation
Old fix that worked only for XR* instructions removed
Test bench tb0 modified to test CY clearance minimally (AC untested!)
Pre-generated vhel test bench tb0 altered accordingly
