242	BUG FIX: The CPU was sometimes fetching a spurious opcode in the 1st cycle after a reset. The cache now has a 'cache_ready' output which the CPU uses to know when NOT to update its IR.	ja_rd	4398d 22h	/ion/trunk/vhdl/SoC/mips_soc.vhdl
234	Added a few GPIO registers to the SoC, updated the DE-1 'top' file to drive the SD interface with the GPIO signals.	ja_rd	4399d 22h	/ion/trunk/vhdl/SoC/mips_soc.vhdl
233	Fixed top entity for De-1 demos: Bootstrap BRAM size is now taken from a constant in the obj code package.	ja_rd	4418d 10h	/ion/trunk/vhdl/SoC/mips_soc.vhdl
224	MCU entity gutted and transformed into a SoC entity Different UART, new generics...	ja_rd	4547d 04h	/ion/trunk/vhdl/SoC/mips_soc.vhdl
223	MCU entity renamed to SoC, moved to separate SoC directory	ja_rd	4547d 04h	/ion/trunk/vhdl/SoC/mips_soc.vhdl
200	CPU interrupt input changed to 8-bit vector Other modules changed accordingly Interrupts still missing; this is just preparing the interface	ja_rd	4871d 21h	/ion/trunk/vhdl/demo/mips_mpu.vhdl
193	Major test bench reorganization: 1.- TB now uses same object code as synthesizable demo. 2.- TB now simulates full MPU system. 3.- Console logging moved to TB package. 4.- Code sample makefiles and modelsim script updated accordingly.	ja_rd	4873d 12h	/ion/trunk/vhdl/demo/mips_mpu.vhdl
191	Separated object code stuff from mcu entity Object code related stuff now lives in separate file Makefiles for code samples updated accordingly Old mcu template deprecated but still in place	ja_rd	4877d 22h	/ion/trunk/vhdl/demo/mips_mpu.vhdl
188	updated hello demo mpu file	ja_rd	4886d 15h	/ion/trunk/vhdl/demo/mips_mpu.vhdl
138	updated simulation & synthesis pre-generated entities ('hello' code sample)	ja_rd	4931d 21h	/ion/trunk/vhdl/demo/mips_mpu.vhdl
129	updated pregenerated demo ('hello')	ja_rd	4934d 19h	/ion/trunk/vhdl/demo/mips_mpu.vhdl
119	Updated pre-generated simulation and synthesis demos	ja_rd	4989d 21h	/ion/trunk/vhdl/demo/mips_mpu.vhdl
98	CPU rd and wr data address buses unified	ja_rd	5023d 02h	/ion/trunk/vhdl/demo/mips_mpu.vhdl
94	Pregenerated demo 'hello' files updated	ja_rd	5033d 22h	/ion/trunk/vhdl/demo/mips_mpu.vhdl
76	Adapted pregenerated vhdl files to latest changes	ja_rd	5043d 20h	/ion/trunk/vhdl/demo/mips_mpu.vhdl
68	Updated pre-generated vhdl files	ja_rd	5044d 12h	/ion/trunk/vhdl/demo/mips_mpu.vhdl
59	cleaned up top vhdl module of demo moved reset sync ff chain to top module updated pre-generated demo file	ja_rd	5046d 02h	/ion/trunk/vhdl/demo/mips_mpu.vhdl
57	updated precompiled demo: single 32-bit BROM instead of 4x8-bit	ja_rd	5046d 15h	/ion/trunk/vhdl/demo/mips_mpu.vhdl
46	First version of cache: stub, 1-word cache Stub cache tested on simulation and HW, just a stub Adapted CPU stall logic to 1st version of cache Adapted all other modules for compatibility with cache	ja_rd	5046d 18h	/ion/trunk/vhdl/demo/mips_mpu.vhdl
40	pre-generated 'hello' demo updated	ja_rd	5050d 21h	/ion/trunk/vhdl/demo/mips_mpu.vhdl
