167 Updated the spec to reflect changes in the CC register: the user break
flag, and the ability to command a clearing of the instruction cache.
dgisselq 2897d 03h /zipcpu/trunk/doc/
164 Updated with inputs from Hellwig Geisse regarding the details of the ECO32
CPU.
dgisselq 2905d 09h /zipcpu/trunk/doc/
163 Trimmed OR1K instruction set down from 219 instructions, to the minimum number
of 48. Thanks to Olof for helping identify the minimal set!
dgisselq 2913d 11h /zipcpu/trunk/doc/
162 Noted 64-bit integers are by extension, as are vector instructions. dgisselq 2913d 11h /zipcpu/trunk/doc/
161 Initial version of the ORConf slides, showing only the initial CPU survey. dgisselq 2913d 11h /zipcpu/trunk/doc/
153 Adds internal link functionality to the specification document format. dgisselq 2928d 23h /zipcpu/trunk/doc/
139 Changes necessary to document the changed instruction set: LDIHI became MPY,
and MPYU and MPYS became MPYUHI and MPYSHI respectively. See the specification
for more details.
dgisselq 2968d 08h /zipcpu/trunk/doc/
107 Adding a missing file. dgisselq 3021d 01h /zipcpu/trunk/doc/
106 Updated to allow building without the sources for the graphics used in the
document.
dgisselq 3021d 04h /zipcpu/trunk/doc/
92 Adjustments made to match the simplified early branching. dgisselq 3067d 01h /zipcpu/trunk/doc/
85 Minor update/correction to operand B definition. dgisselq 3092d 23h /zipcpu/trunk/doc/
79 Adjusted the opcodes for NOOP, BREAK, and LOCK. dgisselq 3097d 03h /zipcpu/trunk/doc/
78 Found/corrected annoying bug in floating point documentation of the opcode
table.
dgisselq 3097d 03h /zipcpu/trunk/doc/
73 Documentations updates. dgisselq 3098d 03h /zipcpu/trunk/doc/
72 Some updated graphics, now containing images of the CPU that include the
divide and (currently non-existant) floating point unit.
dgisselq 3098d 03h /zipcpu/trunk/doc/
69 This implements the "new Instruction Set" architecture for the Zip CPU. It's
a massive change set, that touches just about everything but probably not
enough of everything. Please see the spec.pdf for a description of this
new architecture.
dgisselq 3104d 07h /zipcpu/trunk/doc/
68 Updated specification, includes well illustrated pipeline discussion. dgisselq 3139d 07h /zipcpu/trunk/doc/
67 Includes timing diagrams in support of a very descriptive specification section. dgisselq 3139d 08h /zipcpu/trunk/doc/
49 Final set of changes finishing the Dhrystone package. Dhrystone, as
implemented by hand in assembly, now works.
dgisselq 3185d 01h /zipcpu/trunk/doc/
47 Added some new graphics, includes the file for the Zip Bones system. dgisselq 3185d 01h /zipcpu/trunk/doc/
