R8

Allwinner R8 is SoC designed based on A13 featuring one core Cortex-A8 ARM CPU with Cedar Engine VPU and Mali400 GPU.

=Overview=

Main components of the R8:

 * 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 R8 is a modified version of the A13, targeted to IoT devices.
