[/] [vg_z80_sbc/] [trunk/] [rtl/] [top_vg_z80.v] - Rev 36

Rev	Log message	Author	Age	Path
35	New directory structure.	root	5628d 17h	/vg_z80_sbc/trunk/rtl/top_vg_z80.v
30	Update top-level with new features, update comments, update backplane for front panel, and other peripherals.	hharte	5713d 21h	/vg_z80_sbc/trunk/rtl/top_vg_z80.v
13	Changed I/O addressing so addresses are not shifted left by two bits. Commented out DDR controller, and replaced with 8K of SRAM. Replaced FLASH memory interface with 4K SRAM. Added Vector HD/FD Disk Controller, using FLASH memory for storage. This design can now boot Vector Graphic 56K CP/M 2.2. But be aware that there is only 12K in the TPA, since the Spartan3E does not have enough block RAM to make more. This system is enough to test the Z80 core more thorougly. The EXZ80ALL.COM program on the included disk image tests all documented Z80 instructions. Some tests pass, some don't. This means there is more work to be done on the wb_z80 core.	hharte	5721d 02h	/vg_z80_sbc/trunk/rtl/top_vg_z80.v
4	Update SRAM module, minor fixes to load MON43x Monitor ROM into SRAM.	hharte	5726d 13h	/vg_z80_sbc/trunk/rtl/top_vg_z80.v
3	Initial checkin. Not yet complete.	hharte	5728d 02h	/vg_z80_sbc/trunk/rtl/top_vg_z80.v
