Bobcat () From Wikipedia, the free encyclopedia

Bobcat is a microarchitecture created by AMD aimed at low- power/low-cost market. Bobcat Produced From early 2011 to It was revealed during a speech from AMD executive vice- present president Henri Richard in Computex 2007 and was put into Common AMD production Q1 2011.[1] One of the major supporters was executive vice-president Mario A. Rivas who felt it was difficult to manufacturer(s) compete in the market with a single core optimized for the Min. feature size 40 nm 10-100 Watts range and actively promoted the development of Instruction set AMD64 the simpler core with a target range of 1-10 Watts. In addition, it was believed that the core could migrate into the hand-held Socket(s) Socket FT1 space if the power consumption can be reduced to less than 1 W. (BGA-413) Successor Jaguar Bobcat cores are used together with GPU cores in accelerated Core name(s) AMD APU processing units (APUs) under the "Fusion" brand.[2][3] 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,[4] detailing the specifications and advantages of extending x86 "everywhere".

Design

The Bobcat x86 CPU core design has since been completed and implemented in AMD APU processor products with a TDP of 18 W or less. The core is targeted at low-power markets like netbooks/nettops, ultra-portable laptops, consumer electronics and the embedded market. Since its launch, Bobcat-based CPUs have also been used by OEMs on larger laptops. Architecture specifics:[5]

64-bit core Out-of-order execution Advanced Dual x86 instruction decoder 64-bit integer unit with two ALUs Floating-point unit with two 64-bit pipes Single channel 64-bit 32 KiB instruction + 32 KiB L1 cache 512 KiB - 1 MiB L2 cache MMX, SSE, SSE2, SSE3, SSSE3, SSE4A GPU: TeraScale 2

In February 2013, AMD detailed plans for a successor to Bobcat codenamed Jaguar.
