CoWare SystemC Checkpointing

gearsContinuing on my series of posts about checkpointing in virtual platforms (see previous posts Simics, Cadence, our FDL paper), I have finally found a decent description of how CoWare does things for SystemC. It is pretty much the same approach as that taken by Cadence, in that it uses full stores a complete process state to disk, and uses special callbacks to handle the connection to open files and similar local resources on a system. The approach is described in a paper called  “A Checkpoint/Restore Framework for SystemC-Based Virtual Platforms”, by Stefan Kraemer and Reiner Leupers of RWTH Aachen, and Dietmar Petras, and Thomas Philipp of CoWare, published at the International Symposium on System-on-Chip, in Tampere, Finland, in October of 2009.

There will be lots of finger-pointing in the coming weeks, with the opposition parties trying to smear this on the government. However, I don’t see what the government could have done other than possibly postpone the inevitable.

Power Architecture Rip Van Winkle

For some reason (I guess it is the job…) I was browsing through the Power ISA version 2.06 specification last week and hit the following gem of an instruction: “rvwinkle“. It is named after a short story I had never heard about, but which apparently is sufficiently well-known in the US literary canon to warrant a sleep mode being named after it.
