163 Trimmed OR1K instruction set down from 219 instructions, to the minimum number
of 48. Thanks to Olof for helping identify the minimal set!
dgisselq 2828d 22h /zipcpu/trunk/
162 Noted 64-bit integers are by extension, as are vector instructions. dgisselq 2828d 22h /zipcpu/trunk/
161 Initial version of the ORConf slides, showing only the initial CPU survey. dgisselq 2828d 23h /zipcpu/trunk/
160 Logic updates, and bug fix corrections to bring this in line with the current
XuLA2-LX25 SoC version. (i.e., the XuLA version was debugged and improved,
this update pushes those improvements to the mainline.)
dgisselq 2844d 10h /zipcpu/trunk/
159 Now supports building a simulator that can load ELF files, such as GCC and/or
binutils will produce.
dgisselq 2844d 10h /zipcpu/trunk/
158 Now automatically builds the toolchain by default. dgisselq 2844d 10h /zipcpu/trunk/
157 Added the divide unit to the list of ZipCPU dependencies. dgisselq 2844d 10h /zipcpu/trunk/
156 Fixed a compiler warning for an unused result. dgisselq 2844d 10h /zipcpu/trunk/
155 Improved debug trace quality, for finding bugs after the fact. dgisselq 2844d 10h /zipcpu/trunk/
154 Added timing checks on the busy and valid signals: either one of the two is
valid, or the whole is idle.
dgisselq 2844d 10h /zipcpu/trunk/
153 Adds internal link functionality to the specification document format. dgisselq 2844d 10h /zipcpu/trunk/
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 2877d 08h /zipcpu/trunk/
151 Minor formatting change. dgisselq 2877d 08h /zipcpu/trunk/
150 Minor changes. dgisselq 2877d 08h /zipcpu/trunk/
149 Updated the Makefile documentation and the all target. dgisselq 2877d 08h /zipcpu/trunk/
148 Minor changes to get LONG_MPY working, and adjust the documentation. dgisselq 2877d 09h /zipcpu/trunk/
147 Cleans up div_tb a bit, causing it to write SUCCESS out if successful and
abort if not.
dgisselq 2877d 09h /zipcpu/trunk/
146 Fixes a problem where the assembler complained the compiler was trying to
move .org backwards. This is now fixed.
dgisselq 2877d 09h /zipcpu/trunk/
145 This fixes the pipelined memory problem that was introduced a while back to
fix ... pipelined memory conflicts. This appears to maintain the success
of the fix, while recovering the pipeline memory performance that was had
before.
dgisselq 2877d 09h /zipcpu/trunk/
144 Makes the auto-reload capability a configuration option, and fills out the
reset so that it is properly implemented.
