63 Simplified logic. dgisselq 3011d 03h /
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 3011d 03h /
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.
dgisselq 3011d 03h /
60 LONG_MPY upgrade. This is part of swapping out the LDIHI instruction for a
MPY, and the MPYS and MPYU instructions for MPYSHI and MPYUHI respectively.
dgisselq 3011d 03h /
59 Simplified logic. dgisselq 3011d 03h /
58 Bug fix: the UART can now be reconfigured post-boot without a BREAK condition. dgisselq 3011d 03h /
57 Fixed the TX/RX addresses so that they match the documentation: TX first, then
RX.
dgisselq 3019d 03h /
56 Brings code in line with the OpenCores core: parameterizes the reload value,
and the number of bits in the timer.
dgisselq 3019d 03h /
55 Updated copyright notice. dgisselq 3019d 03h /
54 Updated copyright notice. dgisselq 3019d 03h /
53 Added a touch of error checking. dgisselq 3059d 03h /
52 This brings the XuLA2-LX25 SoC up to speed with the rest of the ZipCPU, and
prepares it for the 32x32 bit multiply instruction set change.
dgisselq 3059d 03h /
51 Lots of bug fixes. The ugliest were in the prefetch cache, where instructions
from one cache line were being issued as valid in another. Other fixes include
pipeline fixes so that LOD (Rx),Rx; LOD(Rx),Rx works, and more. Finally, the
decode was adjusted so that brev no longer affects the flags.
dgisselq 3069d 02h /
50 Updates to fix some broken early branching code, both in idecode and pfcache. dgisselq 3078d 04h /
49 Added some documentation to make the read and write calls easier to understand. dgisselq 3087d 04h /
48 Cleaned up the documentation a touch. It no longer reads like the bugs I used
to debug are still being debugged ...
dgisselq 3089d 06h /
47 Fixes the "NAN" clocks/second output, as well as making input timing come closer
to a realistic timing. (I actually don't know what timing the JTAG port is
providing, but ... the new timer is closer.)
dgisselq 3089d 06h /
46 This is a bug fix release--fixing the bug that kept dumpsdram.cpp/wbsdram.v
from working when long pipelined reads were interrupted by the necessity of
a pair of refresh cycles.
dgisselq 3089d 06h /
45 Minor cosmetic change, eliminates a warning in Xilinx's XISE but offers no
functional difference.
dgisselq 3093d 02h /
44 NELM parameter adjusted to reflect the maximum number of lines the compressed
scope can handle: 31, not 32.
dgisselq 3093d 02h /
