251	Extracted COP0 logic to separate module within CPU. Preliminary step for COP0 refactor. No change in functionality.	ja_rd	3791d 11h	/
250	Precompiled demo object code package is now the bootloader and not the Hello World demo.	ja_rd	4216d 15h	/
249	Cleaned up bootloader.	ja_rd	4216d 15h	/
248	Fixed silly typo in sd bootloader.	ja_rd	4216d 15h	/
247	Added a precompiled binary of 'Adventure' ready to be bootloaded from an SD card.	ja_rd	4216d 16h	/
246	Added a SD-card bootloader demo. Now we can load binaries from the DE-1 board SD interface. This saves time because we no longer have to resynthesize the core to try new software. AND we can now run from 16-bit RAM, which should be faster than 8-bit flash...	ja_rd	4216d 16h	/
245	Modified 'Adventure' demo: added a make target to build a 'bootloadable' version of the binary. The new binary ('code.bin') can be loaded and run from RAM at address 0x0 using the sdboot demo bootloader.	ja_rd	4216d 16h	/
244	New link script that puts everything on XRAM (16-bit SRAM on the DE-1 board). Programs linked with this script will have to be 'bootloaded' on RAM.	ja_rd	4216d 16h	/
243	Added a port of ElmChan's FatFS library for the DE-1 board. Uses bit-banged SPI interface so it should be trivially easy to port to other boards.	ja_rd	4216d 16h	/
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	4216d 17h	/
241	Updated simulation and synthesis object code packages with latest build of 'hello' minidemo.	ja_rd	4216d 17h	/
240	Added a few comments and minor changes to the DE-1 top entity.	ja_rd	4216d 17h	/
239	Fixed simulation script: the test bench does not need to use the obj code package, all it needs is in the simulation parameters package, including the code.	ja_rd	4216d 17h	/
238	BUG FIX: C startup code that copied initialized data to data section was wrong when initialized data was not a multiple of 4 bytes.	ja_rd	4216d 21h	/
237	Fixed test bench to work with latest modifications of SoC	ja_rd	4216d 21h	/
236	Added macros to SoC header file for easy access to GPIO registers	ja_rd	4217d 18h	/
235	Fixed comments in cache module	ja_rd	4217d 18h	/
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	4217d 18h	/
233	Fixed top entity for De-1 demos: Bootstrap BRAM size is now taken from a constant in the obj code package.	ja_rd	4236d 05h	/
232	Fixed bug in object code package generation. This bug was causing spurious behaviors in the Hello demo.	ja_rd	4236d 06h	/
