187 Updated to match changed register definitions within the core. dgisselq 2158d 09h /zipcpu/trunk/bench/
186 Now allows profile dumping for ELF executables. dgisselq 2158d 09h /zipcpu/trunk/bench/
185 Now includes the proper flags for building with ELF executable file support. dgisselq 2158d 09h /zipcpu/trunk/bench/
172 Added a test to see if the compiler properly handles a large number of
arguments. Further, the sibcall enabled compiler now correcly makes a
sibcall from the end of txreg().
dgisselq 2158d 09h /zipcpu/trunk/bench/
168 An updated version of the intensive CPU test. This one runs from C, and
requires a UART port and a PIC, but can run quite successfully on multiple
SoCs that have been built with the ZipCPU internal to them.
dgisselq 2219d 09h /zipcpu/trunk/bench/
159 Now supports building a simulator that can load ELF files, such as GCC and/or
binutils will produce.
dgisselq 2251d 05h /zipcpu/trunk/bench/
155 Improved debug trace quality, for finding bugs after the fact. dgisselq 2251d 05h /zipcpu/trunk/bench/
154 Added timing checks on the busy and valid signals: either one of the two is
valid, or the whole is idle.
dgisselq 2251d 05h /zipcpu/trunk/bench/
152 Updated to match the new/updated multiply instructions. Of course, this is
still hand optimized and not compiled--so it's not really a true and proper
test (yet), but ... it's what I have.
dgisselq 2284d 03h /zipcpu/trunk/bench/
151 Minor formatting change. dgisselq 2284d 03h /zipcpu/trunk/bench/
150 Minor changes. dgisselq 2284d 03h /zipcpu/trunk/bench/
149 Updated the Makefile documentation and the all target. dgisselq 2284d 03h /zipcpu/trunk/bench/
148 Minor changes to get LONG_MPY working, and adjust the documentation. dgisselq 2284d 03h /zipcpu/trunk/bench/
147 Cleans up div_tb a bit, causing it to write SUCCESS out if successful and
abort if not.
dgisselq 2284d 03h /zipcpu/trunk/bench/
140 Minor changes, but fixes build of zippy_tb.cpp. dgisselq 2287d 17h /zipcpu/trunk/bench/
134 Working updates, to keep this up to date with the RTL code. dgisselq 2305d 05h /zipcpu/trunk/bench/
105 Fixed some nasty early branching bugs. Adjusted the Makefile to declare that
cpudefs.h was automatically generated from cpudefs.v, and made sure that
zipbones included the cpudefs.v so it could get the DEBUG_SCOPE define.
In addition, the test.S was updated to test long jumps, the early branching
bug we found, and all three early branching instructions: ADD #x,PC, LOC(PC),PC,
and LDI #x,PC.
dgisselq 2348d 14h /zipcpu/trunk/bench/
87 Adjusted the operator input line to reflect actual logic inputs, rather
than the registered inputs which may have been out of date. (Indeed, they
were out of date for the bug I was chasing and fixed ...)
dgisselq 2415d 05h /zipcpu/trunk/bench/
86 Removed the requirement to have the dev.scope.cpu hardware defined outside
of the Zip CPU (it was defined in another project). This was causing a bus
error in the simulator (which it should have), but taking it out fixes things
in the simulator (while removing capability from one special piece of H/W).
dgisselq 2415d 05h /zipcpu/trunk/bench/
77 First check-in: the test bench for the divide instruction. dgisselq 2420d 08h /zipcpu/trunk/bench/
76 The biggest change here was to zippy_tb, to make it more similar to the debugger
and to make it work with VLIW-type instructions.
dgisselq 2420d 08h /zipcpu/trunk/bench/
75 Modified for VLIW instructions. dgisselq 2420d 09h /zipcpu/trunk/bench/
74 Added a bunch of debugging code to the Dhrystone benchmark assembly file, as
well as two new testing assembly files.
dgisselq 2420d 09h /zipcpu/trunk/bench/
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 2426d 13h /zipcpu/trunk/bench/
58 Added a rudimentary profiling support to the simulator. dgisselq 2487d 14h /zipcpu/trunk/bench/
57 Some bug fixes to the dhrystone benchmark, and some compile time defines for
the test bench processor. Of the most important note is the fix to detect
lockups on the debug/wishbone bus--that has been a real help in getting the
ZipCPU installed and the debugger working on the various boards I'm working
with. (i.e., it's helped me find and figure out why/when things haven't worked)
Of other note is the new 'G' key in the testbench code, to cause the test
bench to run without user interaction until the next keystroke. This is
very valuable in long programs, as it makes getting to/from breakpoints
easier (i.e. you don't have to wait as long, hit 'G', breathe, hit 'space'
and you're there).
dgisselq 2497d 16h /zipcpu/trunk/bench/
50 Dhrystone benchmark updates--added the copyright notice. (Oops!) dgisselq 2507d 07h /zipcpu/trunk/bench/
43 Minor edits to the C++ testbench. dgisselq 2507d 08h /zipcpu/trunk/bench/
42 Oops -- forgot to add the stack. dgisselq 2507d 08h /zipcpu/trunk/bench/
41 Assembly file for the Dhrystone benchmark added. dgisselq 2507d 08h /zipcpu/trunk/bench/
