Rev	Log message	Author	Age	Path
23	new version! - new wishbone bus adapter added (com1_core) - conditional move instructions added	zero_gravity	3883d 21h	/
22	DOC update (error corrections)	zero_gravity	3890d 21h	/
21	New repository setup for the brand new Atlas 2k Processor!	zero_gravity	3898d 19h	/
20	re-init of project repository	zero_gravity	3898d 19h	/
19	bug fixes in: - MMU.vhd - BUS_INTERFACE.vhd initial setup of "atlas-x2" project folder	zero_gravity	4151d 00h	/
18	huge update: - doc update - several bug-fixes in MMU, CTRL and BUS_INTERFACE.vhd have fun ;)	zero_gravity	4173d 21h	/
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	4184d 01h	/
16	- assembler update: assembler can now include other files using the ".include" statement - doc update: fixed error in instruction summary table	zero_gravity	4196d 03h	/
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	4203d 04h	/
14	- instruction set summary card added to documentary (Atlas Processor Datasheet) - minor edits in SYS_REG.vhd and ATLAS_pkg.vhd files	zero_gravity	4204d 00h	/
13	- new option added to the RT/GT/STPC instructions - ATLAS_MICRO implementation scheme added (+testbench) - huge DOC update	zero_gravity	4218d 19h	/
12	- assembler: dev c++ project changed to 32-bit - atlas_asm.exe is now compiled for 32-bit system	zero_gravity	4241d 01h	/
11	- optimized memory components -> less access hardware -> easier mapping for quartus sythesis tool	zero_gravity	4243d 19h	/
10	- optimized opcode decoder - deleted HALT signal from Atlas Micro - not feasible here - doc update	zero_gravity	4243d 20h	/
9	- ATLAS_MICRO implementation example added to project (CPU + I/D memory)	zero_gravity	4244d 21h	/
8	- bug-fix: MSR read access - new instruction added: SPR (store parity of register to T-flag) - doc update - assembler update	zero_gravity	4244d 23h	/
7	- data path diagram added to documentary (finally!!) - updated assembler version - updated assembler examples	zero_gravity	4248d 00h	/
6	- more code examples added to documentary - minor updates for RTL files - assembler now supports binary and hexadecimal number representation	zero_gravity	4250d 22h	/
5	- error corrected in data sheet's branch table asm example	zero_gravity	4256d 03h	/
4	- complete update	zero_gravity	4256d 03h	/
