88 Adjusted copyright date. dgisselq 2910d 17h /xulalx25soc/trunk/rtl/
87 Placed the interrupt into the carry chain for less logic area. dgisselq 2910d 17h /xulalx25soc/trunk/rtl/
86 Fine tuning the `defines, so that you can build pipelined without pipelined
bus access and so forth.
dgisselq 2910d 17h /xulalx25soc/trunk/rtl/
85 First version of the SD-SPI interface, with partial functionality. (No the
empty link that was here before.)
dgisselq 2914d 14h /xulalx25soc/trunk/rtl/
84 First part of switching to proper sdspi.v, and not just the link. dgisselq 2914d 14h /xulalx25soc/trunk/rtl/
83 Fixes a bug in the LX9 build whereby the flash was never ever granted permission
to use the SPI port.
dgisselq 2915d 18h /xulalx25soc/trunk/rtl/
74 Adds the SD-card capability, and connects the debug wires to/from the uartdev
in case it needs to be debugged.
dgisselq 2916d 14h /xulalx25soc/trunk/rtl/
73 Simplified logic. dgisselq 2916d 14h /xulalx25soc/trunk/rtl/
72 Sets XULA25 as the default. dgisselq 2916d 14h /xulalx25soc/trunk/rtl/
71 Needed to play with subtle timing to get this to build. Expect me to play
with these two clock numbers more.
dgisselq 2916d 14h /xulalx25soc/trunk/rtl/
70 Cosmetic (minor) update. dgisselq 2916d 14h /xulalx25soc/trunk/rtl/
69 Massive logic simplification. This is also the first (verified) working
version.
dgisselq 2916d 14h /xulalx25soc/trunk/rtl/
68 Fixes the debug ack line, so it no longer acks when there isn't a dbg_stb.
Fixed the multiply option parameter, so it sets a 3-clock multiply properly.
Adjusted the watchdog timer so that it now produces a timer that doesn't
reload--since this is pointless for a watchdog. Finally, connects a reset
line to the DMA, to make certain that resetting the CPU will also reset any
ongoing DMA operation.
dgisselq 2916d 14h /xulalx25soc/trunk/rtl/
67 Simplifies logic, and guarantees that the minimum set value will always
produce an int. For example, if the count was X before, setting X-1 wouldn't
produce an interrupt since it had passed. Now it produces an interrupt, and
keeps the next interrupt valid.
dgisselq 2916d 14h /xulalx25soc/trunk/rtl/
66 Simplified logic (barely). dgisselq 2916d 14h /xulalx25soc/trunk/rtl/
65 Makes the auto-reload feature a parameterized (generic) feature, so the same
code will work for both auto-reloadable and non-autoreloadable (i.e. watchdog)
timers.
dgisselq 2916d 14h /xulalx25soc/trunk/rtl/
64 First (verified) working version. dgisselq 2916d 14h /xulalx25soc/trunk/rtl/
63 Simplified logic. dgisselq 2916d 14h /xulalx25soc/trunk/rtl/
62 Removed the pipe logic from the non-pipelined version, and made the NOOP a
specific ALU instruction so that the PC is always properly updated.
dgisselq 2916d 14h /xulalx25soc/trunk/rtl/
61 Fixed the timing control wires: busy and valid will never both be true. Busy
will be true (now) until valid is asserted, and busy will never not be
asserted until valid is true.
