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 4623d 08h /
79 DAA logic fixed and simplified ja_rd 4623d 09h /
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 4629d 09h /
77 Fixed a few mistakes in the last code reorganization.
Mostly bad paths but also a broken comment in the UART source...
ja_rd 4630d 08h /
76 Corrected some minor issues in the core description document. motilito 4637d 00h /
75 Updated file list ja_rd 4640d 15h /
74 Testbenches for VHDL core moved to sw/tb.
Added a mini-demo for the VHDL SoC on the DE-1 dev board.
Added a mini-testbench for the VHDL SoC.
ja_rd 4640d 15h /
73 New tool for VHDL object code constant generation.
Old VHDL template tool moved to tools directory.
ja_rd 4640d 15h /
72 Added specs document for VHDL/Verilog CPU core ja_rd 4640d 15h /
71 IMSAI manual removed, no longer used ja_rd 4640d 15h /
70 Added new VHDL SoC for demonstration purposes ja_rd 4640d 15h /
69 New simulation scripts for Modelsim in new separate directory.
Includes old test benches for CPU VHDL core and new test benches for SoC VHDL core
ja_rd 4640d 15h /
68 Corrected ihex2vlog tool to enable explicit RAM declaration for Spartan 2. motilito 4651d 11h /
67 Corrected bugs in the Small-C compiler. motilito 4652d 13h /
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 4667d 11h /
65 Adding Verilog initial version to the svn.
Added the c80 Small-C compiler and AS80 assembler.
motilito 4678d 19h /
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
ja_rd 4687d 19h /
63 Modified syntax of ARGV parameter for compatibility to later versions of Perl ja_rd 4687d 19h /
62 Changed all hard tabs to spaces as preamble to a minor refactor ja_rd 4688d 05h /
