252 Extracted COP0 logic to separate module within CPU.
No change in functionality.		 ja_rd 3797d 05h /ion/trunk/
251 Extracted COP0 logic to separate module within CPU.
Preliminary step for COP0 refactor.
No change in functionality.		 ja_rd 3797d 19h /ion/trunk/
250 Precompiled demo object code package is now the bootloader and not the Hello World demo. ja_rd 4222d 23h /ion/trunk/
249 Cleaned up bootloader. ja_rd 4222d 23h /ion/trunk/
248 Fixed silly typo in sd bootloader. ja_rd 4222d 23h /ion/trunk/
247 Added a precompiled binary of 'Adventure' ready to be bootloaded from an SD card. ja_rd 4222d 23h /ion/trunk/
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 4223d 00h /ion/trunk/
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 4223d 00h /ion/trunk/
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 4223d 00h /ion/trunk/
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 4223d 00h /ion/trunk/
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 4223d 01h /ion/trunk/
241 Updated simulation and synthesis object code packages with latest build of 'hello' minidemo. ja_rd 4223d 01h /ion/trunk/
240 Added a few comments and minor changes to the DE-1 top entity. ja_rd 4223d 01h /ion/trunk/
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 4223d 01h /ion/trunk/
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 4223d 05h /ion/trunk/
237 Fixed test bench to work with latest modifications of SoC ja_rd 4223d 05h /ion/trunk/
236 Added macros to SoC header file for easy access to GPIO registers ja_rd 4224d 01h /ion/trunk/
235 Fixed comments in cache module ja_rd 4224d 01h /ion/trunk/
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 4224d 01h /ion/trunk/
233 Fixed top entity for De-1 demos: Bootstrap BRAM size is now taken from a constant in the obj code package. ja_rd 4242d 13h /ion/trunk/
232 Fixed bug in object code package generation.
This bug was causing spurious behaviors in the Hello demo.		 ja_rd 4242d 14h /ion/trunk/
231 Updated file list ja_rd 4371d 05h /ion/trunk/
230 Modelsim script updated to latest HW changes ja_rd 4371d 06h /ion/trunk/
229 Code samples updated to use new VHDL config packages and new SoC (UART). ja_rd 4371d 06h /ion/trunk/
228 SW simulator updated
Simulation of UART adapted to new hardware.
Added simulation of debug registers.		 ja_rd 4371d 07h /ion/trunk/
227 Removed modules no longer used:
code_rom_pkg replaced by new package in SoC directory.
RS232 sub-modules replaced by new UART		 ja_rd 4371d 07h /ion/trunk/
226 Updated demo and test bench to use new SoC entity. ja_rd 4371d 07h /ion/trunk/
225 Added utility functions for the initialization of BRAM memories. ja_rd 4371d 07h /ion/trunk/
224 MCU entity gutted and transformed into a SoC entity
Different UART, new generics...		 ja_rd 4371d 07h /ion/trunk/
223 MCU entity renamed to SoC, moved to separate SoC directory ja_rd 4371d 07h /ion/trunk/
