SEMIFIVE, a design solution provider, has announced the successful commercialisation of its 5nm HPC SoC Platform with its lead partner Rebellions, a South Korean AI hardware and software solution start-up.

This is SEMIFIVE’s second commercialisation of its SoC Platform built on Samsung Foundry’s FinFET process technologies.

Designed to realise custom HPC chips and ASICs for end applications such as high-end AI accelerators, hyperscale data centres, cloud servers, network and storage processors, this HPC SoC Platform solution significantly lowers chip development cost, shortens time to market with reduced development risks.

The SoC Platform includes a high-performance interleaved memory system consisting of 4 channels of GDDR6 and 16 lanes of PCIe Gen5 high speed interface. Together with a quad-core 64-bit Arm Cortex-A53 CPU cluster for balanced high performance and compute power efficiency, the platform includes complete system and other peripheral IPs which are all pre-verified and integrated.

Rebellions’ ATOM SoC is designed to deliver inference performance across different types of ML tasks, computer vision, natural language processing and recommendation models.

The custom SoC achieved excellent ResNet50 (Single Stream Latency: 0.239ms) and BERT-Large (Single Stream Latency: 4.297ms) scores on the latest MLPerf Inference v3.0 benchmark.

As a lead partner for SEMIFIVE’s SoC Platform programme, Rebellions and SEMIFIVE teams collaborated closely to ensure all critical requirements including Rebellions’ neural core IP are all fully integrated into the final ATOM SoC.

With first time right silicon execution, SEMIFIVE was able to deliver complete packaged parts and evaluation boards which enabled Rebellions to verify its high-speed ATOM performance, as well as demonstrate industry leading inference performance and latency results.

Rebellions is expected to commence mass production of ATOM SoCs from middle of 2024.

“This marks another highlight of our proven SoC Platform technology and total custom chip design capabilities. We are proud to collaborate with our lead partner Rebellions for the 5nm HPC SoC Platform and more importantly excited to see the ATOM project moving into volume production stage,” said Brandon Cho, CEO and founder of SEMIFIVE. “We will continue to contribute for innovations in the custom silicon industry as a leading DSP of Samsung Foundry SAFETM Ecosystem.”

SEMIFIVE’s SoC platform solution drastically lowers chip development cost, turnaround time and risks, allowing more diverse industry players to innovate and challenge the semiconductor landscape.
