BBV Research

I've developed some tools for generating Basic Block Vectors as used by the SimPoint analysis tool.

My paper that appears in HiPEAC 2008 describes this work. The results are validated against hardware performance counters on x86 Linux.

Here are links to the various tools:

valsim - generate BBVs using valgrind
qemusim - generate BBVs using qemu
dynsim - I worked on a dyninst method of doing this. It was way too resource intensive, but the code is available in case you are curious.

Here are slowdown numbers for the various tools
