21	New repository setup for the brand new Atlas 2k Processor!	zero_gravity	3773d 08h	/atlas_core/trunk/
20	re-init of project repository	zero_gravity	3773d 09h	/atlas_core/trunk/
19	bug fixes in: - MMU.vhd - BUS_INTERFACE.vhd initial setup of "atlas-x2" project folder	zero_gravity	4025d 14h	/atlas_core/trunk/
18	huge update: - doc update - several bug-fixes in MMU, CTRL and BUS_INTERFACE.vhd have fun ;)	zero_gravity	4048d 10h	/atlas_core/trunk/
17	- new interrupt vector: unique vector for undefined instructions / access violations ("command error trap") - bug fix in assembler: correct absolute address generator - assembler works fine now ;)	zero_gravity	4058d 14h	/atlas_core/trunk/
16	- assembler update: assembler can now include other files using the ".include" statement - doc update: fixed error in instruction summary table	zero_gravity	4070d 16h	/atlas_core/trunk/
15	- new instruction added: NEG Rd, Rx (Rd <- 0 - Ra) - instruction is built from redundant SUB with identical operands (SUB Rd, Ra, Ra; will always result in 0) - since there are other instructions to clear a register, the redundant SUB has been recoded to perform the NEG operation - NEG operation added to documentary and assembler	zero_gravity	4077d 17h	/atlas_core/trunk/
14	- instruction set summary card added to documentary (Atlas Processor Datasheet) - minor edits in SYS_REG.vhd and ATLAS_pkg.vhd files	zero_gravity	4078d 13h	/atlas_core/trunk/
13	- new option added to the RT/GT/STPC instructions - ATLAS_MICRO implementation scheme added (+testbench) - huge DOC update	zero_gravity	4093d 09h	/atlas_core/trunk/
12	- assembler: dev c++ project changed to 32-bit - atlas_asm.exe is now compiled for 32-bit system	zero_gravity	4115d 15h	/atlas_core/trunk/
11	- optimized memory components -> less access hardware -> easier mapping for quartus sythesis tool	zero_gravity	4118d 09h	/atlas_core/trunk/
10	- optimized opcode decoder - deleted HALT signal from Atlas Micro - not feasible here - doc update	zero_gravity	4118d 10h	/atlas_core/trunk/
9	- ATLAS_MICRO implementation example added to project (CPU + I/D memory)	zero_gravity	4119d 11h	/atlas_core/trunk/
8	- bug-fix: MSR read access - new instruction added: SPR (store parity of register to T-flag) - doc update - assembler update	zero_gravity	4119d 12h	/atlas_core/trunk/
7	- data path diagram added to documentary (finally!!) - updated assembler version - updated assembler examples	zero_gravity	4122d 13h	/atlas_core/trunk/
6	- more code examples added to documentary - minor updates for RTL files - assembler now supports binary and hexadecimal number representation	zero_gravity	4125d 12h	/atlas_core/trunk/
5	- error corrected in data sheet's branch table asm example	zero_gravity	4130d 16h	/atlas_core/trunk/
4	- complete update	zero_gravity	4130d 16h	/atlas_core/trunk/
3	- bug-fix of compare/test instruction in assembler program - minor edits in rtl files to make a more efficient use of config constants	zero_gravity	4132d 09h	/atlas_core/trunk/
2	initial repository setup	zero_gravity	4133d 11h	/atlas_core/trunk/
