Kanter dissects Jaguar, but not an actual cat
David Kanter saved up his in-depth write-up of AMD's compact Jaguar CPU microarchitecture for April 1, for some reason. I'm not quite sure what happened there. Maybe I'm not reading carefully enough. Anyhow, you can read his take on perhaps AMD's most important CPU architecture, the one that powers the PS4 and Xbox One, right here.
If you've enjoyed David's architecture pieces, I'd suggest taking the time to read this one. David has recently joined the Microprocessor Report and will be publishing many of his big architecture write-ups at MPR going forward. Unless you subscribe to MPR, those articles may prove hard to access.
