9 Updated verification data. jdoin 4715d 20h /
8 Updated Documentation jdoin 4715d 20h /
7 Updated code comments in VHDL files, added readme.txt files, updated work-in-progress version of the .doc core specification manual. jdoin 4716d 10h /
6 v1.10.0075: Changed clocking to use a single high-speed clock for the whole core, using clock enables to control slower timing.
Added SPI line clock divider from high-speed system clock.
Added pipeline delay logic to sync phase of SCK and MOSI, enabling very high operating frequencies.
Verified in silicon for SCK and MOSI at 50MHz, with very robust operation.		 jdoin 4718d 07h /

Verified in silicon for SCK and MOSI at 50MHz, with very robust operation.		 jdoin 4718d 07h /
4 v0.97.0068 - streamlined resets and clock enables to reduce area
v0.97.0075 - redesigned parallel interfaces, with pipelined data transport for async clock domains
v0.97.0083 - fixed bug "CPHA effect": redesigned SCK output circuit
v0.97.0086 - removed master MISO input register: got 33MHz.		 jdoin 4743d 08h /
3 - fixed fsm async glitches at state changes
- changed async clears to sync resets
- improved idle state logic for parallel interface
- added cross-clock register buffers
- exposed internal state and nets for debug		 jdoin 4752d 06h /
2 v0.95.0050 - Master/Slave loopback verified at 25MHz. jdoin 4760d 11h /
1 The project and the structure was created root 4774d 06h /
