The Puma Family 16h is a low-power microarchitecture by AMD for its APUs. It succeeds the Jaguar as a second-generation version, targets the same market, and belongs to the same AMD architecture Family 16h. The Beema line of processors are aimed at low-power notebooks, and Mullins are targeting the tablet sector.

Design

The Puma cores use the same microarchitecture as Jaguar, and inherits the design:

• Out-of-order execution and Speculative execution, up to 4 CPU cores
• Puma does not feature clustered multi-thread (CMT), meaning that there are no "modules"
• Two-way integer execution
• Two-way 128-bit wide floating-point and packed integer execution
• Integer hardware divider
• Puma does not feature Heterogeneous System Architecture or zero-copy^[2]
• 32 KiB instruction + 32 KiB data L1 cache per core
• 1–2 MiB unified L2 cache shared by two or four cores
• Integrated single channel memory controller supporting 64bit DDR3L
• 3.1 mm² area per core

Instruction set support

Like Jaguar, the Puma core has support for the following instruction sets and instructions: MMX, SSE, SSE2, SSE3, SSSE3, SSE4a, SSE4.1, SSE4.2, AVX, F16C, CLMUL, AES, BMI1, MOVBE (Move Big-Endian instruction), XSAVE/XSAVEOPT, ABM (POPCNT/LZCNT), and AMD-V.^[1]
