Octasic’s New System-on-Chip DSPs Are Optimized for Small Cells, Portable Base Stations and Specialized Handsets

OCT3032 low power SoCs provide the highest processing capacity per watt for small cell designs with 2G to 5G flexibility

MONTREAL, Canada, February 22, 2019 – Octasic, the leader in low power wireless and media processing solutions, today announced its latest high performance System-on-Chip (SoC). Incorporating Opus3, Octasic’s third-generation digital signal processor (DSP) core architecture, the OCT3032 SoC is optimized to provide the highest processing capacity per watt for 2G to 5G small cells, network-in-a-box (NiB) applications, private wireless deployments, defense tactical communications, public safety, and Industrial Internet of Things (IIoT) networks.

The OCT3032 features 32 programmable DSP cores coupled with on-chip hardware accelerators and an embedded quad-core Arm® Cortex®-A7 processor, enabling it to provide up to 800 Mbps LTE downlink throughput. Octasic’s unique self-clocking DSP core architecture optimizes power consumption without compromising performance, through low latency interconnects, an on-chip video encoder/decoder engine, internal communication security, and scalable power management through power islands. Its integrated hardware accelerators for wireless encoding/decoding, security protocols, video, and error control make it ideal for software defined radio (SDR) applications.

“In terms of performance, our new OCT3032 System-on-Chip can handle over 25 times more throughput capacity for wireless base stations than our previous devices,” said David Sanchez, Chief Technology Officer at Octasic. “We have designed the OCT3032W to address the lower power and higher density requirements of LTE and 5G network rollouts. It is not only smaller with more processing power than our previous devices, a single OCT3032 device can support up to four independent simultaneous SDR air interfaces, making it possible to develop 2G to 5G capabilities on this one device. When you combine these hardware improvements with the ability to reuse Octasic’s field-proven, carrier-grade flexiPHY software, we think the benefits to OEMs and developers are obvious.”

Arm on-board

The OCT3032 includes a CPU complex with an embedded quad-core Arm Cortex-A7 processor and all necessary interfaces, allowing a single OCT3032 to run a complete on-chip base station, including the host-based 3GPP protocol stacks and core network software.

Flexible dual-mode operation

The OCT3032 can operate as either a base station or as a user equipment (UE). By using the same component on both sides of the air interface, OEMs can simplify and accelerate application development, especially for applications like private radio networks with a focus on security, defense and industrial IoT.

Video processing engine

To satisfy specialized application requirements for video streaming in private networks, the OCT3032 includes a video encoder/decoder block with H.265/H.264 processing capabilities. Moreover, solutions based on the OCT3032 can benefit from the device’s programmable power consumption profiles and anti-tampering security options.

Ultra low power consumption for battery-based systems

Maintaining low power consumption to extend battery life in compact small cells and other battery-based portable wireless systems does not mean a trade-off with performance, throughput, or capacity. Octasic’s patented asynchronous DSP core technology eliminates state-elements and clock trees, making the OCT3032 significantly smaller and less power-consuming than a traditional synchronous DSP architecture with similar performance characteristics.

Opus Studio software development suite

For OEMs or developers with requirements for custom applications or custom functionality, Octasic offers Opus Studio, its Integrated Development Environment (IDE) that provides a visual framework to accelerate development of embedded applications. Opus Studio includes a full-featured suite of tools for code editing, optimizing, compiling, profiling, and debugging.


OCT3032 devices are being manufactured in Europe and Octasic’s early access partners are already receiving sample devices. OCT3032 based evaluation and development platforms for wireless applications will become available to customers starting in Q2 2019.
