101 Fixed the `defines at the top so that this can be built without any CPU.
This was then used to measure the impact of the CPU on the entire build, as
you could now build with no CPU, and then with a CPU to compare.
dgisselq 2920d 22h /xulalx25soc/trunk
100 Includes updates so this can run at higher clocks speeds within an FPGA. dgisselq 2920d 23h /xulalx25soc/trunk
99 Includes high-speed updates. rxuart and txuart will now run at 200MHz on
an Artix-7, so should not impact timing (any more) on the XuLA platform.
dgisselq 2920d 23h /xulalx25soc/trunk
98 Updated copyright notices for the new year, to reflect that changes have been
made in 2016.
dgisselq 2920d 23h /xulalx25soc/trunk
97 Latest working bit file, with all changes attached as of this date. dgisselq 2944d 02h /xulalx25soc/trunk
96 Now accepts an SD-Card backing file, so that SD-Card reads *and* writes can be
tested.
dgisselq 2944d 02h /xulalx25soc/trunk
95 Added write capability to the SD-SPI simulator. dgisselq 2944d 03h /xulalx25soc/trunk
94 Fixes a bug which had caused the device to die artificially and early, just
simply because the program connecting to the simulator shut its pipe down before
getting our last message. We now ignore this signal and continue.
dgisselq 2944d 03h /xulalx25soc/trunk
93 Oops -- missed adjusting the copyright. dgisselq 2944d 03h /xulalx25soc/trunk
92 Fixes the problem whereby the master counters show when the user counters should
be showing and vice versa. Now the master counters show by default, together
with their correct labels. User counters are still available by pressing
'u' in the debugger, and the master counter display may be returned to by
pressing 'm' in the debugger.
dgisselq 2944d 03h /xulalx25soc/trunk
91 Fixes bugs associated with an overflow of write acknowledgements in the
receiver. This helps keep our accesses aligned.
dgisselq 2944d 03h /xulalx25soc/trunk
90 Reads and writes to the SD over SPI port now work. The card appears, as of now,
to be fully functional.
dgisselq 2944d 03h /xulalx25soc/trunk
89 Bug fixes, following the adf_ce logic combining ALU/DIVIDE/FPU pipeline logic
into one register, this fixes that logic so that instructions without their
condition fulfilled are still "executed" and marked as done.
dgisselq 2944d 03h /xulalx25soc/trunk
88 Adjusted copyright date. dgisselq 2944d 03h /xulalx25soc/trunk
87 Placed the interrupt into the carry chain for less logic area. dgisselq 2944d 03h /xulalx25soc/trunk
86 Fine tuning the `defines, so that you can build pipelined without pipelined
bus access and so forth.
dgisselq 2944d 03h /xulalx25soc/trunk
85 First version of the SD-SPI interface, with partial functionality. (No the
empty link that was here before.)
dgisselq 2948d 00h /xulalx25soc/trunk
84 First part of switching to proper sdspi.v, and not just the link. dgisselq 2948d 00h /xulalx25soc/trunk
83 Fixes a bug in the LX9 build whereby the flash was never ever granted permission
to use the SPI port.
dgisselq 2949d 04h /xulalx25soc/trunk
82 dgisselq 2949d 23h /xulalx25soc/trunk
81 Adds register values for the SD-Card registers. dgisselq 2949d 23h /xulalx25soc/trunk
80 Currently working version: contains both a working DMA controller as well as
a working (as far as I can tell) SD-Card controller (writes not yet tested).
dgisselq 2949d 23h /xulalx25soc/trunk
79 Adds 'bench' and 'sw' targets, and automatically builds them (now). dgisselq 2949d 23h /xulalx25soc/trunk
78 Comments out the line that caused a compiler warning--setting an unused
variable. Code should be better as a result.
dgisselq 2949d 23h /xulalx25soc/trunk
77 Adds register names and values for the SD card interface. dgisselq 2949d 23h /xulalx25soc/trunk
76 Now tries to avoid reading from the stack if the stack addresses are already
known to be bad. That way, the debugger tries to preserve any bus error address
already on the buserr device.
dgisselq 2949d 23h /xulalx25soc/trunk
75 Added simulation capability for the SD-Card, as well as debugging output for the
DMA. (The SD-Card debug may not be fully featured, yet, but it has gotten me
to where I can talk to the card.)
dgisselq 2949d 23h /xulalx25soc/trunk
74 Adds the SD-card capability, and connects the debug wires to/from the uartdev
in case it needs to be debugged.
dgisselq 2949d 23h /xulalx25soc/trunk
73 Simplified logic. dgisselq 2949d 23h /xulalx25soc/trunk
72 Sets XULA25 as the default. dgisselq 2949d 23h /xulalx25soc/trunk
