FPGAs Enable the Next Generation of Communication and Networking Solutions (WP021)

Communications and networking systems that extend from the edges of the 5G network to the switches inside data centers are placing extreme pressure on the ability of silicon to support the computational and data-transfer rates they require. Traditionally programmable logic provided the best mixture of flexibility and speed for these systems, but has been challenged in recent years by the increase in speed. Through the inclusion of an innovative, multilevel network on chip that allows data to be streamed easily around the device without impacting the FPGA fabric, the Speedster7t architecture ensures all device resources are used to their full potential.

Eight Benefits of Using an FPGA with an On-chip High-Speed Network (WP020)

Since the initial introduction of FPGAs decades ago, each new architecture has continued to employ a bit-wise routing structure. While this approach has been successful, the rise of high-speed communication standards has required ever increasing on-chip bus widths to be able to support these new data rates. Achronix's solution was to create a revolutionary 2D high-speed network on chip (NoC) on top of the traditional segmented FPGA routing structure for its new Speedster7t FPGA family.

How to Design SmartNICs Using FPGAs to Increase Server Compute Capacity (WP017)

Intelligent server adapters, or SmartNICs, boost server performance in cloud and private data centers by offloading network processing workloads and tasks from server CPUs. Offloading network processing to a SmartNIC is not a new concept — for example, there are NICs that offload some network-processing functions such as checksum computation and segmentation. However, the rapid explosion in data-center network traffic driven by software-defined networking (SDN), Open vSwitch (OVS), and network functions virtualization (NFV) demands a new class of NIC with even greater offload capabilities: the SmartNIC.

Chiplets - Taking SoC Design Where no Monolithic IC has Gone Before (WP016)

The well-documented slowing of Moore's Law is the key driver behind the movement towards the use of chiplets in the design and manufacture of new, high-performance semiconductor devices. While the monolithic IC has been the ultimate design target for many decades, there have always been reasons to build certain devices with multiple die using multi-chip modules (MCMs), whether it was for additional memory capacity or to fabricate chips based on IP blocks that require incompatible IC processes.

Mine Cryptocurrencies Sooner, Faster, and Cheaper with Achronix Speedcore Embedded FPGAs (WP014)

New cryptocurrencies such as Monero introduce ASIC-resistance and memory-hardness to prevent ASICs from being built that give some operators a competitive mining advantage over others who do not have access to the same technology. This white paper discusses the relevant background and presents a solution based on Achronix Speedcore™ embedded FPGAs (eFPGAs), enabling users to regain a highly profitable advantage over competing solutions.

Migrating to Achronix eFPGA Technology (AN014)

Many users transitioning to Achronix eFPGA technology will be familiar with existing FPGA solutions from other vendors. Although Achronix technology and tools are similar to existing FPGA technology and tools, there are some differences. Understanding these differences are needed to achieve the very best performance and quality of results (QoR).

Using Encrypted Source Files with ACE (AN008)

Designers need a way to protect their source IP, and that is often achieved by way of encrypted RTL. Achronix's tool flow using ACE and SynplifyPro supports the use of encrypted IP to enable protection of all or part of an IP's RTL.

Pipelining the CPU Interface (AN016)

A Speedcore instance hosted in an SoC supports three different configuration modes: CPU, serial flash and JTAG. In CPU mode, an external CPU acts as the master and controls the programming operations for the Speedcore eFPGA, and offers a high-speed method for loading configuration data.

Repeatability in ACE (AN012)

One of the desired requirements of any FPGA design tool is the ability to reproduce the exact same results every time the tool is run under the same conditions — a requirement refereed to as repeatability. The ACE placer and router are deterministic, delivering 100% repeatability.

Speedster7t Component Library User Guide (UG086)

The Achronix Speedster7t component library provides the user with building blocks that may be instantiated into the user’s design. These components provide access to low-level fabric primitives, complex I/O blocks, and higher level design components. Each library element entry describes the operation of the component as well as any parameters that must be initialized. Verilog and VHDL templates are also provided to aide in the implementation of the user’s design.
