Achieving ASIC Timing Closure with Speedcore eFPGAs (WP013)

Achronix's Speedcore eFPGA IP allows companies to embed a programmable logic fabric in their ASICs, delivering to end users the capability to modify or upgrade the functionality of an ASIC after being deployed in the field. This flexibility dramatically expands the solution space that can be served by the ASIC as it can be updated to support changing standards and algorithms. Timing closure is particularly challenging due to the fact that the eFPGA fabric may host any number of designs over the course of device operation. Each of those designs must work independently with the rest of the ASIC, and timing closure can only be said to have been met if all of the possible designs targeting the eFPGA fabric can meet timing.

AI Benchmarking on Achronix Speedster®7t FPGAs (WP999)

Deployments of machine learning networks with auto-regressive critical paths, or recurrence, often poorly utilize AI accelerator hardware. Such networks, like those used in automatic speech recognition (ASR), must run with low latency and deterministic tail-latency for at-scale real-time applications. In this paper, the team at Myrtle.ai presents an overlay architecture for an inference engine which is then implemented on a Speedster7t FPGA. The team further highlights the benefits of the AI-optimized Speedster7t architecture for low-latency, real-time applications.

Software-Defined Hardware Provides the Key to High-Performance Data Acceleration (WP019)

Across a wide range of industries, data acceleration is the key to building efficient, smart systems. A number of accelerator technologies have appeared to fill the gap that are based on custom silicon, graphics processors or dynamically reconfigurable hardware, but the key to their success is their ability to integrate into an environment where high throughput, low latency and ease of development are paramount requirements. A board-level platform developed jointly by Achronix and BittWare has been optimized for these applications, providing developers with a rapid path to deployment for high-throughput data acceleration.

The Achronix Integrated 2D NoC Enables High-Bandwidth Designs (WP028)

Devices aimed at addressing modern algorithm acceleration workloads must be able to efficiently move high-bandwidth data streams between high-speed interfaces and throughout the device. Achronix Speedster®7t FPGAs can process these high-bandwidth data streams via an integrated new and highly innovative two-dimensional network on chip (2D NoC). This white paper discusses two methods of implementing a 2D NoC and presents an example design to show how the Achronix 2D NoC improves performance, reduces area, and reduces design time when compared to a soft 2D NoC implementation.
