Rev	Log message	Author	Age	Path
35	CPU mem_wait logic updated to work with cache	ja_rd	5045d 03h	/ion/trunk/vhdl/mips_cpu.vhdl
30	Completed decoding of instructions (to prevent side effects of invalid opcodes)	ja_rd	5047d 00h	/ion/trunk/vhdl/mips_cpu.vhdl
28	Core updated: supports CP0 cause register and traps in delay slots traps abort next instruction in all cases (incl. jumps/L/S)	ja_rd	5047d 01h	/ion/trunk/vhdl/mips_cpu.vhdl
23	Unimplemented instruction are now trapped (barely tested)	ja_rd	5047d 06h	/ion/trunk/vhdl/mips_cpu.vhdl
22	FIXED killer bug in instruction decoder for beq & mfc0 Decoding was incomplete and beq was using wrong ALU input	ja_rd	5048d 04h	/ion/trunk/vhdl/mips_cpu.vhdl
12	Adapted multiplier unit from Plasma	ja_rd	5048d 17h	/ion/trunk/vhdl/mips_cpu.vhdl
8	Trap handling now works as in the MIPS specs: EPC points to victim instruction (break/syscall)	ja_rd	5049d 18h	/ion/trunk/vhdl/mips_cpu.vhdl
6	Fix: BREAK now aborts load and jump instructions properly	ja_rd	5049d 20h	/ion/trunk/vhdl/mips_cpu.vhdl
2	First commit (includes 'hello' demo)	ja_rd	5050d 06h	/ion/trunk/vhdl/mips_cpu.vhdl
