Puma (microarchitecture)
# Puma (microarchitecture)

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
* Two-way integer execution
* Two-way 128-bit wide floating-point and packed integer execution
* Integer hardware divider
* Puma does not feature clustered multi-thread (CMT), meaning that there are no "modules"
* Puma does not feature Heterogeneous System Architecture or zero-copy
* 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 $mm^2$ 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.

### Improvements over Jaguar

* 19% CPU core leakage reduction at 1.2V
* 38% GPU leakage reduction
* 500 mW reduction in memory controller power
* 200 mW reduction in display interface power
* Chassis temperature aware turbo boost
* Selective boosting according to application needs (intelligent boost)
* Support for ARM TrustZone via integrated Cortex-A5 processor
* Support for DDR3L-1866 memory

## Puma+

AMD released a revision of Puma microarchitecture, Puma+, updating the video decoder from UVD 4.2 to 6.0 and the video encoder from VCE 2.0 to VCE 3.1.
