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	4443d 17h	/light8080/trunk/vhdl/
79	DAA logic fixed and simplified	ja_rd	4443d 17h	/light8080/trunk/vhdl/
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	4449d 18h	/light8080/trunk/vhdl/
77	Fixed a few mistakes in the last code reorganization. Mostly bad paths but also a broken comment in the UART source...	ja_rd	4450d 16h	/light8080/trunk/vhdl/
70	Added new VHDL SoC for demonstration purposes	ja_rd	4461d 00h	/light8080/trunk/vhdl/
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	4508d 04h	/light8080/trunk/vhdl/
61	Basic demo updated: main entity name changed to keep synthesis too happy	ja_rd	4876d 14h	/light8080/trunk/vhdl/
60	Fixed nasty typo in pin constraints file (clock input)	ja_rd	4880d 20h	/light8080/trunk/vhdl/
59	tabs to spaces	ja_rd	4905d 03h	/light8080/trunk/vhdl/
57	removed unfinished CPM demo files	ja_rd	5089d 17h	/light8080/trunk/vhdl/
55	Altair 4K Basic demo on DE-1 board	ja_rd	5089d 17h	/light8080/trunk/vhdl/
54	BUG FIX: XOR operations wre not clearing CY and ACY	ja_rd	5089d 17h	/light8080/trunk/vhdl/
53	added interrupt for single-stepping cleaned up comments a bit	ja_rd	5445d 17h	/light8080/trunk/vhdl/
50	interrupt test bench adapted to the fix in IE instruction	ja_rd	5445d 17h	/light8080/trunk/vhdl/
49	fixed: IE now enables interrupts after a 1-instruction delay (it was enabling interrupts immediately)	ja_rd	5445d 17h	/light8080/trunk/vhdl/
42	test bench 1 regenerated with new template added a test for 'long' intr pulses	ja_rd	5446d 10h	/light8080/trunk/vhdl/
41	test bench 0 regenerated with new template no changes to the test code	ja_rd	5446d 10h	/light8080/trunk/vhdl/
40	test bench template now can simulate intr pulses longer than 1 cycle	ja_rd	5446d 10h	/light8080/trunk/vhdl/
39	fixed: int request (intr) can now be wider than 1 cycle	ja_rd	5446d 10h	/light8080/trunk/vhdl/
38	pin assignment for IMSAI demo removed	ja_rd	5446d 10h	/light8080/trunk/vhdl/
37	IMSAI monitor demo removed	ja_rd	5446d 10h	/light8080/trunk/vhdl/
36	CPM demo on cyclone 2 starter board (work in progress)	ja_rd	5446d 10h	/light8080/trunk/vhdl/
35	CPM demo pin assignment file (Altera Quartus II)	ja_rd	5446d 10h	/light8080/trunk/vhdl/
34	rs232 sanitized and parametrized	ja_rd	5446d 10h	/light8080/trunk/vhdl/
31	New directory structure.	root	5577d 13h	/light8080/trunk/vhdl/
22	Totally changed -- vhdl code generated from a template Interrupts tested from software using a simulated interrupt controller	ja_rd	5597d 19h	/trunk/vhdl/
21	Totally changed -- vhdl code generated from a template	ja_rd	5597d 19h	/trunk/vhdl/
20	VHDL template for test benches	ja_rd	5597d 19h	/trunk/vhdl/
19	Fixed a bug (intr pulses longer than 1 clock cycle failed in some circumstances) Added an output to the core to mark the fetch cycle of all instructions Started to add timing diagrams	ja_rd	5597d 19h	/trunk/vhdl/
13	Minor changes in embedded code changed (success code now stands out better visually) Comments added explaining the TB mechanincs	ja_rd	5683d 22h	/trunk/vhdl/
