Technology

Flex Logix™ Technology

Superior Interconnect

Inference and eFPGA are both data flow architectures. A single inference layer can take over a billion multiply-accumulates. Flex Logix directly connects the compute and RAM resources into a data path, like an ASIC; then repeats this layer by layer. Flex Logix utilizes a new breakthrough interconnect architecture: less than half the silicon area of traditional mesh interconnect, fewer metal layers, higher utilization and higher performance. The ISSCC 2014 paper detailing this technology won the ISSCC Lewis Winner Award for Outstanding Paper. The interconnect continues to be improved resulting in new patents.

Superior Scalability

We can easily scale up our Inference and eFPGA architectures to deliver compute capacity of any size. Flex Logix does this using a patented tiling architecture with interconnects at the edge of the tiles that automatically form a larger array of any size.

TIGHTLY COUPLED SRAM AND COMPUTE

SRAM closely couples with our compute tiles using another patented interconnect. Inference efficiency is achieved by closing coupling local SRAM with compute which is 100x more energy efficient than DRAM bandwidth. This interconnect is also useful for many eFPGA applications.

Superior Software

Our eFPGA compiler has been in use by dozens of customers for several years. Our inference compiler takes Tensorflow Lite and ONNX models to program our inference architecture using our eFPGA compiler in the back end. A performance modeler for our inference architecture is available now.

software driver

Software drivers will be available for common Server OS and real time OS for MCUs and FPGAs.

PCIe CARDS

Flex Logix chip products will be available in PCIe Card format for Edge Servers and Gateways. Other formats like U.2 or M.2 can be supplied as well.

Superior Low-Power Design Methodology

Flex Logix has numerous architecture and circuit design technologies to deliver the highest throughput at the lower power.
