Rev	Log message	Author	Age	Path
191	Cleaned up comments, added back the OPEN8_NULLBUS constant, and added some new modules for ADCs and LCD displays. Also made the button input module more configurable by moving the debounce code to a separate entity and using generics to instantiate it.	jshamlet	1679d 18h	/open8_urisc/trunk/VHDL/o8_vdsm8.vhd
189	Merged changes from private repository, added ceil_log2 function to Open8_pkg, since it is used to calculate RAM vectors, cleaned up comments and removed local copies of the ceil_log2 function from peripherals.	jshamlet	1692d 16h	/open8_urisc/trunk/VHDL/o8_vdsm8.vhd
172	General code cleanup	jshamlet	3224d 16h	/open8_urisc/trunk/VHDL/o8_vdsm8.vhd
167	Updated CPU model; Pipelined ALU control signals to improve fMAX, corrected issue with interrupt controller priority not being obeyed, fixed bug in auto-indexing instructions where the upper register wasn't being properly incremented, cleaned up code to make the processor model easier to follow. Added several useful modules that use the Open8 bus.	jshamlet	4066d 11h	/open8_urisc/trunk/VHDL/o8_vdsm8.vhd
