177 Fixed the illegal address logic to be more precise. dgisselq 2079d 22h /zipcpu/
176 Switched from distributed to block RAM, and adjusted the logic to help
timing closure. The resulting core will build in designs up to 200MHz in
speed.
dgisselq 2079d 22h /zipcpu/
175 Fixed the carry bit for logical shifts: it is the last bit shifted out of the
register. 0x80000000>>32 yields a 0 with carry set. Anything logically
shifted by a number greater than thirty two clears carry and register.
dgisselq 2079d 22h /zipcpu/
174 Simplified the divide to improve timing performance. dgisselq 2079d 22h /zipcpu/
173 Adjusted the pdfinfo field, to accommodate Google's bot. dgisselq 2079d 22h /zipcpu/
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 2079d 22h /zipcpu/
171 This fixes the problem whereby the ZipCPU didn't properly access more than
5 word-sized function parameters.
dgisselq 2082d 04h /zipcpu/
170 Minor updates to the orconf.pdf pre-conference slide. (Added the 'to be
revealed' line.
dgisselq 2091d 22h /zipcpu/
169 Added details of LM32 to the (pre) ORConf survey slide in trunk/doc. dgisselq 2127d 22h /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 2140d 22h /zipcpu/
