Processor

The Rockchip RK3308 Soc used in ROCK Pi S RK3308is a high-performance Quad-coreapplication processor designed for intelligent voice interaction, audio input/output processing, and other digital multimedia applications. Embedded rich audio interfaces,such as I2S, PCM, TDM, PDM, SPDIF, HDMI ARC and so on, can meet different audio application development, reduce hardware developmentcomplexity and development cost.

Quad-core ARM Cortex-A35CPU
Full implementation of the ARM architecture v8-A instruction set
ARM Neon Advanced SIMD (single instruction, multiple data) support for accelerated media and signal processing computation
ARMv8 Cryptography Extensions
In-order pipeline with symmetric dual-issue of most instructions
256KB unified system L2 cache
Include VFP v3 hardware to support single and double-precision operations
Integrated 32KB L1 instruction cache, 32KB L1data cache with 4-way set associative
TrustZone technology support
