[/] [open8_urisc/] [trunk/] [VHDL/] [o8_alu16.vhd] - Rev 193

Rev	Log message	Author	Age	Path
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	1538d 08h	/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.	jshamlet	1538d 08h	/open8_urisc/trunk/VHDL/o8_alu16.vhd
172	General code cleanup	jshamlet	3083d 06h	/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.	jshamlet	3925d 01h	/open8_urisc/trunk/VHDL/o8_alu16.vhd
