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	4221d 09h	/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	4222d 09h	/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	4240d 21h	/ion/trunk/vhdl/SoC/mips_soc.vhdl
224	MCU entity gutted and transformed into a SoC entity Different UART, new generics...	ja_rd	4369d 15h	/ion/trunk/vhdl/SoC/mips_soc.vhdl
223	MCU entity renamed to SoC, moved to separate SoC directory	ja_rd	4369d 15h	/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	4694d 08h	/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	4696d 00h	/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	4700d 09h	/ion/trunk/vhdl/demo/mips_mpu.vhdl
188	updated hello demo mpu file	ja_rd	4709d 02h	/ion/trunk/vhdl/demo/mips_mpu.vhdl
138	updated simulation & synthesis pre-generated entities ('hello' code sample)	ja_rd	4754d 08h	/ion/trunk/vhdl/demo/mips_mpu.vhdl
129	updated pregenerated demo ('hello')	ja_rd	4757d 06h	/ion/trunk/vhdl/demo/mips_mpu.vhdl
119	Updated pre-generated simulation and synthesis demos	ja_rd	4812d 09h	/ion/trunk/vhdl/demo/mips_mpu.vhdl
98	CPU rd and wr data address buses unified	ja_rd	4845d 13h	/ion/trunk/vhdl/demo/mips_mpu.vhdl
94	Pregenerated demo 'hello' files updated	ja_rd	4856d 09h	/ion/trunk/vhdl/demo/mips_mpu.vhdl
76	Adapted pregenerated vhdl files to latest changes	ja_rd	4866d 07h	/ion/trunk/vhdl/demo/mips_mpu.vhdl
68	Updated pre-generated vhdl files	ja_rd	4867d 00h	/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	4868d 13h	/ion/trunk/vhdl/demo/mips_mpu.vhdl
57	updated precompiled demo: single 32-bit BROM instead of 4x8-bit	ja_rd	4869d 02h	/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	4869d 06h	/ion/trunk/vhdl/demo/mips_mpu.vhdl
40	pre-generated 'hello' demo updated	ja_rd	4873d 08h	/ion/trunk/vhdl/demo/mips_mpu.vhdl
