Mingjiada Recycle Rockchip RK2118M 22nm High-Performance Triple-Core HiFi4 DSP Audio Processor

Shenzhen Mingjiada Electronics Co., Ltd. — is currently seeking to purchase brand-new, original Rockchip RK2118M chips globally at competitive prices on a long-term basis. We offer high-value cash payments for factory surplus stock, distributor dead stock and discontinued project materials, helping customers to quickly recover their capital.

Rockchip RK2118M Product Overview
The RK2118M is a high-performance, triple-core HiFi4 DSP audio processor launched by Rockchip. Built using a 22nm process, this multi-core heterogeneous audio SoC is specifically designed for in-vehicle cabin acoustics and high-end smart voice devices, and stands as a benchmark model for high-end audio DSPs manufactured in China.
The RK2118M chip architecture features an integrated design comprising a dual-core STAR-SE MCU, a triple-core HiFi4 DSP and a dedicated audio NPU. Its powerful computing capabilities support complex audio algorithms, significantly simplifying the design of audio hardware solutions.

Key Features (RK2118M)
1. Tri-core HiFi4 DSP Computing Platform
The RK2118M is equipped with three HiFi4 DSP cores, featuring a VLIW (Very Long Instruction Word) architecture and 64-bit SIMD (Single Instruction, Multiple Data) processing capabilities. It supports multi-channel MAC (Multiply-Accumulate) operations in a single cycle, with a total computing power of up to 1.7 GMIPS, enabling the stable execution of high-load audio algorithms such as active noise cancellation, multi-channel audio effects processing and echo cancellation.
2. Built-in Audio AI NPU Hardware Acceleration Unit
The RK2118M integrates a dedicated audio neural network processor supporting FP16 operations, enabling the local deployment of AI audio functions such as voice separation, voice enhancement, spatial virtual surround sound, voiceprint recognition and in-vehicle call noise reduction, without relying on the main controller’s computing power.
3. Comprehensive Hardware Audio Acceleration Engines
The RK2118M features built-in FIR/IIR digital filters and multiple hardware ASRC (Asynchronous Sampling Rate Converter) channels, significantly reducing the computational load on the DSP; it supports Dolby and DTS audio decoding and is compatible with various third-party audio processing algorithms.
4. Comprehensive Multi-Channel Audio Interface Resources
The RK2118M is equipped with 8 SAI channels, 8 PDM channels and multiple SPDIF transceiver interfaces, enabling expansion to a maximum of 32 audio I/O channels and supporting the deployment of large-scale, multi-speaker in-vehicle audio systems.
5. Comprehensive range of general-purpose peripheral interfaces
The RK2118M integrates peripherals such as USB 2.0 OTG, RMII Ethernet, CAN-FD, UART, SPI and GPIO, facilitating seamless communication and integration with the vehicle’s main control unit and amplifier modules.
6. Highly Integrated Memory Design
The RK2118M features 1024KB of on-chip system SRAM and supports XIP (eXecute-in-Place) for direct on-chip code execution. It also supports external DDR2 memory, reducing the number of peripheral components and minimising the PCB footprint.
