A13

Allwinner A13 is SoC with build-in ARM Cortex A8 CPU ARM Mali 400 GPU and Allwinner Cedar Engine VPU, which is also named R8 now

=Overview=

Main components of the A13:

 * CPU: Cortex-A8 1GHz (ARM v7) Processor which have both VFPv3 and NEON co-processors:
 * FPU: Vector Floating Point Unit (standard ARM VFPv3 FPU Floating Point Unit)
 * SIMD: NEON (ARM's extended general-purpose SIMD vector processing extension engine)
 * GPU: Mali400
 * VPU: Cedar Engine (Video Processor Unit for audio and video hardware decoding or encoding)

The A13 is a cheaper version of the A10 which lacks HDMI-transmitter and SATA-controller, as it is primarily targeted towards tablets. The A13 also lacks G2D and therefor needs to rely on NEON code for 2D acceleration.

The R8 is a rename of A13, and primarily targeted towards low-budget IoT devices.
