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.
