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.
5G Advanced and 6G Evolution Powered by FPGA Technology (WP031)
5G, 5G Advanced, and 6G bring many technical and commercial challenges that need to be met if the promised benefits of this new cellular technology are to be truly achieved. Any solution in this space must deal with the evolving specifications — FPGA and eFPGA IP technology is critical to the successful deployment of these next-generation network technologies.
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.
Enabling the Next Generation of 5G Platforms (WP029)
Radio access networks (RANs) and associated core network hierarchy, which link end-user equipment to both the central telecom network and the cloud, are essential in building ubiquitous cellular connectivity to expand the number and breadth of use cases that can be supported by the technology. This paper outlines the current status of 5G standards and rollout, summarizes the new use cases 5G RANs need to support and examines the standards evolution to support higher bandwidth and additional use cases. Finally, it also explains how Achronix FPGA technology can be utilized by developers to meet the fundamental challenge facing them.
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.
Reduce Speech Transcription Costs by up to 90% with CAI (WP030)
Conversational artificial intelligence (CAI) uses deep learning (DL), a subset of machine learning (ML), to automate speech recognition, natural language processing and text to speech using machines. Achronix and Myrtle.ai are teaming up to deliver an ASR platform consisting of a 200W, x16 PCIe Gen4-based accelerator card and the associated software which together can sustain up to 4000 RTS concurrently, processing up to 1 million five-minute transcriptions per 24-hour period — reducing costs by as much as 90% versus cloud-based APIs.
Achronix FPGAs Optimize AI in Industry 4.0 and 5.0 (WP027)
Industry has come a long way over in the last three hundred years. Machines were first introduced in the 1700s, mainly water and steam driven, introducing the Industrial Revolution in the late 1700s. Automation and computer technology would enter the picture in the late 1960's, paving the way for the eventual automation, artificial intelligence (AI) and networked solutions of today. Although it might appear that humans are no longer in the picture, Industry 5.0 is bringing us full circle by combining the precision and efficiency of robotic systems, driven largely by AI, with the ingenuity and real-time thought of the human mind — all leading to more optimal manufacturing environments.
Achronix Speedcore embedded FPGA (eFPGA) IP includes look-up-table, memory, and DSP blocks. Each of these blocks are designed to be modular to allow the definition any mix of resources required for a custom end system.
The Achronix 7nm Speedster7t FPGA family is specifically designed to deliver extremely high performance for demanding applications including data-center workloads and networking infrastructure.

Speedcore User Interface Timing Sign-off Methodology (AN009)
Timing sign-off between the host ASIC and the Speedcore boundary is one of the most crucial steps in ensuring proper integration of a Speedcore instance into a customer's SoC.
The input and output paths between the host SoC and a Speedcore instance are an important test component. It is essential to have a structure that ties seamlessly to the SoC's test flow without requiring special functions such as loading a bitstream in the Speedcore instance.
