194 Cleaned up licensing sections jshamlet 1714d 15h /open8_urisc/trunk/VHDL/o8_alu16.vhd
193 Fixed incorrect comment in o8_alu16.vhd. The value of the write to 0x1F doesn't matter, as the write itself triggers the calculation. jshamlet 1714d 16h /open8_urisc/trunk/VHDL/o8_alu16.vhd
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.

172 General code cleanup jshamlet 3259d 14h /open8_urisc/trunk/VHDL/o8_alu16.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.
