Rev	Log message	Author	Age	Path
181	Altered the RSP instruction to allow the stack pointed to either be restored from registers or stored to registers based on the status of a processor bit. Also modified LDX to simplify the address logic.	jshamlet	1583d 13h	/open8_urisc/trunk/VHDL/Open8_pkg.vhd
172	General code cleanup	jshamlet	3107d 14h	/open8_urisc/trunk/VHDL/Open8_pkg.vhd
169	Corrected issue with CMP and SBC generating an inverted carry flag and added new constants to the package file to simplify interfacing new modules.	jshamlet	3162d 15h	/open8_urisc/trunk/VHDL/Open8_pkg.vhd
153	Fixed bug in interrupt logic that caused stack pointer to increment if interrupt occurred as specific instructions were being decoded, Fixed bug in interrupt logic where instruction caching would remain enabled during an interrupt, causing improper execution depending on what instruction was in the decode stage as the interrupt is trigered.	jshamlet	4765d 06h	/open8_urisc/trunk/VHDL/Open8_pkg.vhd
151	Fixed STO instruction and interrupt logic to avoid address bus corruption issues.	jshamlet	4775d 09h	/open8_urisc/trunk/VHDL/Open8_pkg.vhd
10	corrected implementation for BTT to match V8/ARClite definition, changed sense of reset, corrected comments to match source values	khays	4916d 18h	/open8_urisc/trunk/VHDL/Open8_pkg.vhd
8	Need to learn SVN...	jshamlet	5245d 05h	/open8_urisc/trunk/VHDL/Open8_pkg.vhd
7	Initial Upload	jshamlet	5245d 05h	/open8_urisc/trunk/open8_urisc/VHDL/Open8_pkg.vhd
