direct cache

Postby Rodrigo Navarro » Thu Jan 20, 2005 9:02 pm


I was trying to execute the imgpipe program with a direct cache (lg2Sets=0) but the result was:

./imgpipe -s 1 -o pasta-ppm pasta-jpg
make: *** [test] Segmentation fault

for lg2Sets equal to 1 and 2 there were no problems...

Is that normal?

No, this is not normal. It is caused by a bug in the replacement routine of the cache simulator that always assumes there's more than 1 set in the Dcache. I've updated the VEX distribution at ALaRI, and will post an updated package on the VEX dowlnoad webpage by Jan 22.

Thanks for spotting and reporting this error.
