Bobcat (microarchitecture)

Computer microarchitecture created by AMD From Wikipedia, the free encyclopedia

The AMD Bobcat Family 14h is a microarchitecture created by AMD for its AMD APUs, aimed at a low-power/low-cost market.[1]

It was revealed during a speech from AMD executive vice-president Henri Richard in Computex 2007 and was put into production Q1 2011.[2] 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 W range and actively promoted the development of the simpler core with a target range of 1–10 W. In addition, it was believed that the core could migrate into the hand-held space if the power consumption can be reduced to less than 1 W.

Bobcat cores are used together with GPU cores in accelerated processing units (APUs) under the "Fusion" brand.[3][4] 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,[5] 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:[6]

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