169 Added details of LM32 to the (pre) ORConf survey slide in trunk/doc. dgisselq 2798d 20h /zipcpu/
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 2811d 20h /zipcpu/
167 Updated the spec to reflect changes in the CC register: the user break
flag, and the ability to command a clearing of the instruction cache.
dgisselq 2811d 20h /zipcpu/
166 Bugfix version. This fixes a problem whereby function addresses with offsets
were not properly calculated, together with properly setting up pcrelative
offsets when using the move function together with a label.
dgisselq 2812d 00h /zipcpu/
165 Added a test to make certain that the arithmetic right shift was properly
propagating the high order bit. (The test works under verilator, but didn't
initially work in Xilinx -- thus a difference between the two.)
dgisselq 2812d 00h /zipcpu/
164 Updated with inputs from Hellwig Geisse regarding the details of the ECO32
CPU.
dgisselq 2820d 02h /zipcpu/
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 04h /zipcpu/
162 Noted 64-bit integers are by extension, as are vector instructions. dgisselq 2828d 04h /zipcpu/
161 Initial version of the ORConf slides, showing only the initial CPU survey. dgisselq 2828d 05h /zipcpu/
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 2843d 16h /zipcpu/
