Flex Logix Announces InferX™ High Performance IP for DSP and AI Inference

Markets and Applications

Microcontrollers and SoCs

Your customers often use external FPGAs in conjunction with your chips to interface to non-standard GPIO and to provide acceleration for workloads that benefit from FPGA’s parallelism.

Chip companies can now integrate eFPGA into your MCU or SoC so your customers can lower system cost, system size, and system power while continuing to enjoy the high performance and flexibility of FPGA – just now integrated into your SoC.

You can provide your customers with our software tools to program the eFPGA themselves.

Customers are in development now such as Alphawave.

InferX AI and DSP provide world class acceleration for your SoC.

Communications and Networking

Our customers in these spaces are integrating FPGAs that are adjacent to their SoCs.

5G wireless communications companies use FPGA to handle the radio head country-by-country and operator-by-operator customizations and to adapt to the continuingly evolving 5G standard in the field after the equipment is deployed. eFPGA can run as fast as the FPGA it replaces: for example 500MHz over the full process and temperature range for 7nm.

Customers are in development now such as Socionext.

InferX DSP provides very high throughput for signal processing with full reconfigurability – Your SoC can have the DSP performance of the fastest FPGA at a fraction of the power and cost.

Computational Storage

FPGAs are now being shipped with Smart SSDs to enable local processing of data to offload host processors.

With FPGA wear loading algorithms can be updated in the field, encryption algorithms can be upgraded as needed to stay ahead of hackers, and FPGA parallelism can process local data much faster than a remote host.

Now Smart SSDs can integrate eFPGA into their controllers to cut cost and power by 5-10x and cut size while keeping the full speed and flexibility of FPGA.



Up to a dozen FPGAs are used in the most advanced automobiles for a wide range of applications from small to large.

Integrating FPGAs into SoCs in the automobile will cut power and cost by 5-10x and reduce size and weight.

Customers such as Morning Core (a subsidiary of Datung Telecommunications) are already deploying eFPGA in Automotive applications.

InferX DSP and AI can be used for radar, autonomous driving, cabin surveillance, backup and more. InferX can eliminate bulky FPGAs and GPUs and integrate them into companion SoCs saving money and power while keeping speed and flexibility.

Aerospace and Defense

FPGAs are used in every aerospace and defense application. US-manufactured eFPGA for SoCs reduce dependence on Taiwan.

Flex Logix eFPGA is in production on Sandia in Albuquerque and GlobalFoundries in NY, and is in development for TSMC’s new Arizona Fabs. eFPGA for other US fabs is planned.

Some of our eFPGA ports are Rad Hard by Design (RHBD).

Customers include AFRL, Boeing, the Department of Defense, Sandia and other government agencies and prime contractors.

InferX DSP and AI will be available on TSMC 5/4/3nm nodes manufactured in Arizona enabling world class DSP and AI made in the USA at a fraction of the size, power and cost of discrete DSP-FPGAs and GPUs.

Cloud Computing

In 2023 we will announce hardware and software advances that enable the integration of Millions of LUTs in advanced FinFet nodes (5nm and below).

This will enable Cloud Computing companies to integrate very large FPGA into their NiC, Networking, Security and Switch chips cutting power and cost by 5-10x and increasing compute density.

Other Applications

FPGA is used in all sorts of systems, so eFPGA will be deployed in a wide range of other systems as well such as “Micro FPGAs” (ForgeFPGA family from Renesas), mixed signal ICs with digital programmability, Financial Trading, Signal Processing, High Speed Test, Industrial Automation, Robotics and more.
