Rev	Log message	Author	Age	Path
171	CPU bug fix: MFC0 instructions aborted by privilege trap should not modify any register	ja_rd	4898d 10h	/ion/
170	Fixed bug in optional emulation of EXT, INS	ja_rd	4898d 20h	/ion/
169	Fixed bug in emulation of CLO instruction Added support for simulated hardware IRQs (incomplete)	ja_rd	4898d 20h	/ion/
168	Updated 'opcodes' simulation script to NOT use simulated mips32 instructions and trap instead (as the real CPU does)	ja_rd	4898d 20h	/ion/
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	4898d 22h	/ion/
166	Modified simulator, added some debug functionality: - Optional emulation of some MIPS32r2 opcodes - Function call trace log using map file (crude implementation) Plus a few small bug fixes	ja_rd	4898d 22h	/ion/
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	4904d 06h	/ion/
164	Minor typo fixes in source file	ja_rd	4904d 06h	/ion/
163	SW simulator update: Better disassembly format (hastily tested) New parameters: start address, breakpoint address, whether or not to trap reserved opcodes	ja_rd	4904d 07h	/ion/
162	Fixed stupid mistake in headers (date of project)	ja_rd	4904d 22h	/ion/
161	Added GPL license info to the vhdl headers This project is becoming respectable :)	ja_rd	4904d 22h	/ion/
160	BUG FIX: the cache init code was messing the BSS initialization	ja_rd	4906d 00h	/ion/
159	bug detected but not fixed in cpu (1st instruction after entering user mode is executed in kernel mode)	ja_rd	4906d 07h	/ion/
158	removed file from TB directory which was committed by mistake	ja_rd	4906d 07h	/ion/
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	4907d 17h	/ion/
156	project doc somewhat updated (but still out of date)	ja_rd	4908d 00h	/ion/
155	Temporary warning added to outdated project doc file	ja_rd	4908d 01h	/ion/
154	fixed log trigger address in hello makefile	ja_rd	4908d 02h	/ion/
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	4908d 02h	/ion/
