Bobcat is a processor codenamed and designed by AMD. The processor's existence was revealed during a speech from AMD executive vice-president Henri Richard in Computex 2007 held in Taiwan; it is expected to be launched in Q4 2010. One of the major supporters was executive vice-president Mario A. Rivas who felt it was difficult to compete in the x86 market with a single core optimized for the 10-100 watts range and actively promoted the development of the simpler core with a target range of 1-10 watts. In addition, the core could migrate into the hand-held space by reducing the power consumption down to 250 mW.
The Bobcat processor is an x86 CPU core aiming at TDP value between 1 to 10 W, together with low voltage operation, the processor was aimed at consumer electronic markets. According to now former executive vice-president of AMD, Dave Orton, Bobcat would make its debut in UMPC devices, OLPC devices, handheld devices, and other small form factor devices.
Bobcat will support out-of-order execution, advanced branch predictor, dual x86 instruction decoder, 64-bit integer unit with two ALUs, floating point unit with two 64-bit pipes, 32KB instruction cache, 32KB data cache, and half clock speed 512KB L2 cache. Bobcat will also support modern SIMD extensions like SSE, SSE2, SSE3, SSSE3, SSE4A, but no 3DNow or AVX.
The Bobcat core will be incorporated together with GPU cores into processors under the "Fusion" brand. A simplified architecture diagram was released at AMD's Analyst Day in November 2009. This is similar in concept with earlier AMD research in 2003, detailing the specifications and advantages of extending x86 "everywhere".
