185w ago - Yesterday Niraj Khadka (aka bluemimmosa) TweetedGeoHot (who is currently entering a university level competiton at NASA in Florida) that he has started work on support for the PS3 Cell SPU (Synergistic Processing Unit), and has shared a PS3 Cell SPU Cheat Sheet WIP with other PlayStation 3 developers.
To quote from the Tweets: "bluemimmosa: @geohot spu.isdf February 14, 2010 Started work on support for the Cell SPU whats with EDA????? any news.."
"geohot: in Florida for http://www.nasa.gov/lunabotics/ CMU team"

-Dissassembler/Assembler or IDA plugin for extensions
-Scanning for memory corruptions/vulnerabilities (This has been possible since the first dump was published and has yet to be done)
-reversing reference (It's easier with IDA tools and IBM docs)
Cheat-sheets can be useful. I guess the value of this cheat sheet is a quick binary-to-hex conversion (second column). However, I would still find the original documentation easier to use: SPU_ISA_v1.2_27Jan2007_pub.pdf (google) page 32 starts the opcodes.
Another note on the utility of repackaging information:
Sure, the same info in Norton's PC Assembly book could've been found in Intel docs. However, it sure was easier to read the way Norton arranged the same information. No problem in trying to make the information easier to use.
