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	4784d 21h	/ion/trunk/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	4789d 06h	/ion/trunk/vhdl/
188	updated hello demo mpu file	ja_rd	4797d 23h	/ion/trunk/vhdl/
171	CPU bug fix: MFC0 instructions aborted by privilege trap should not modify any register	ja_rd	4828d 15h	/ion/trunk/vhdl/
162	Fixed stupid mistake in headers (date of project)	ja_rd	4835d 03h	/ion/trunk/vhdl/
161	Added GPL license info to the vhdl headers This project is becoming respectable :)	ja_rd	4835d 03h	/ion/trunk/vhdl/
159	bug detected but not fixed in cpu (1st instruction after entering user mode is executed in kernel mode)	ja_rd	4836d 12h	/ion/trunk/vhdl/
158	removed file from TB directory which was committed by mistake	ja_rd	4836d 12h	/ion/trunk/vhdl/
157	Bug fix in the missing coprocesor exception. The CPU was triggering a privilege exception for the mtc0 that went into user mode. Logging HDL updated	ja_rd	4837d 22h	/ion/trunk/vhdl/
153	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	4838d 07h	/ion/trunk/vhdl/
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	4838d 07h	/ion/trunk/vhdl/
151	BUG FIX: major bugs fixed in cache module 1.- sram address was wrong (leftover from previous version) 2.- writes to unmapped areas were blocking the cache 3.- Sequence SW,LW produced a RAW data hazard in some cases	ja_rd	4838d 07h	/ion/trunk/vhdl/
145	MAJOR UPDATE: first version of D-Cache	ja_rd	4840d 21h	/ion/trunk/vhdl/
141	BUG FIX in cache: cpu stall logic was missing key case 2nd SW in a (cached) row was not being stalled	ja_rd	4842d 11h	/ion/trunk/vhdl/
140	BUG FIX in cpu: MTCx was using Rs as source instead of Rt BUG FIX in cpu: cached sequences of S* were failing, byte_we logic was wrong	ja_rd	4842d 11h	/ion/trunk/vhdl/
139	updated simulation & synthesis pre-generated entities ('hello' code sample)	ja_rd	4843d 05h	/ion/trunk/vhdl/
138	updated simulation & synthesis pre-generated entities ('hello' code sample)	ja_rd	4843d 05h	/ion/trunk/vhdl/
136	Added debug output to synthesizable MPU template, and connected debug signals to LEDs	ja_rd	4843d 05h	/ion/trunk/vhdl/
134	Added 'unmapped access' flag to CPU core, meant for debug mostly. Eventually this flag will trigger an interrupt.	ja_rd	4843d 05h	/ion/trunk/vhdl/
133	First draft of the SDRAM controller (Still unused in the code working base)	ja_rd	4846d 02h	/ion/trunk/vhdl/
