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 4748d 12h /ion/trunk/src/
192 Code ROM template for MCU
Contains bootstrap object code to be placed on BRAM		 ja_rd 4752d 21h /ion/trunk/src/
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 4752d 21h /ion/trunk/src/
190 VHDL object code builder script updated
Now can insert project name into target file		 ja_rd 4752d 21h /ion/trunk/src/
189 fixed opcode test makefile: adapted to new common makefile ja_rd 4760d 20h /ion/trunk/src/
185 FIX: committed forgotten source file for 'memtest' demo...
Updated memtest makefile		 ja_rd 4787d 09h /ion/trunk/src/
184 Updated some application makefiles to make use of common makefile ja_rd 4787d 09h /ion/trunk/src/
183 Updated comments and readme file for code samples ja_rd 4789d 01h /ion/trunk/src/
182 Updated makefiles for Hello and Adventure
Removed old dependencies in Adventure demo		 ja_rd 4789d 02h /ion/trunk/src/
181 Bug fix: left out a link script in last commit ja_rd 4789d 02h /ion/trunk/src/
180 Removed old support code
Bits of it may yet reappear as part of the new support library		 ja_rd 4789d 12h /ion/trunk/src/
179 'Adventure' demo updated, removed dependencies to old support code ja_rd 4789d 12h /ion/trunk/src/
178 Added FP math support to support library
Uses code lifted from old version of GNU libc, no adaptation needed
NEEDS testing!		 ja_rd 4789d 12h /ion/trunk/src/
177 Modified 'Adventure' demo to use new support code ja_rd 4789d 13h /ion/trunk/src/
176 Modified 'hello' to use new support code
NOTE: the 'OPCODE EMULATOR' mentioned below is the TRAP HANDLER
The SW opcode emulation has been working for months		 ja_rd 4789d 13h /ion/trunk/src/
175 Updated support library
Removed spurious dependence to accursed '_impure_ptr'		 ja_rd 4789d 13h /ion/trunk/src/
174 started to add branch emulation to opcode emulator ja_rd 4789d 13h /ion/trunk/src/
173 New version of support code, still incomplete. ja_rd 4789d 13h /ion/trunk/src/
172 Added new version of support code, still incomplete ja_rd 4791d 04h /ion/trunk/src/
168 Updated 'opcodes' simulation script to NOT use simulated mips32 instructions and trap instead (as the real CPU does) ja_rd 4792d 17h /ion/trunk/src/
167 Updated simulation script for 'hello' sample: now uses function call log.
It is useless in this demo, but it shows how to use it.		 ja_rd 4792d 18h /ion/trunk/src/
165 Added (very early draft, very incomplete) reserved opcode trap handler.
Updated opcode tester to test some emulated mips32 opcodes using the trap handler.		 ja_rd 4798d 02h /ion/trunk/src/
164 Minor typo fixes in source file ja_rd 4798d 02h /ion/trunk/src/
162 Fixed stupid mistake in headers (date of project) ja_rd 4798d 18h /ion/trunk/src/
161 Added GPL license info to the vhdl headers
This project is becoming respectable :)		 ja_rd 4798d 18h /ion/trunk/src/
160 BUG FIX: the cache init code was messing the BSS initialization ja_rd 4799d 20h /ion/trunk/src/
154 fixed log trigger address in hello makefile ja_rd 4801d 22h /ion/trunk/src/
152 Added R3000 compatible support for kernel/user state:
- Implemented KU/IE plus KUp/IEp and KUo/IEo status bits
- Updated startup and test code to account for changes
- Implemented bit DID NOT TEST rfe instruction (not used in code)
- Access to CP0 in user mode triggers 'CpU' trap
- Updated software simulator

Besides, the logging of HI/LO register changes has been temporarily disabled, there's an unfixed bug in it.		 ja_rd 4801d 22h /ion/trunk/src/
150 Bug fix: added missing nop in vacant branch delay slot ja_rd 4802d 20h /ion/trunk/src/
149 changed size of simulated flash in opcodes sample code ja_rd 4802d 20h /ion/trunk/src/
