modern FPGAs contain a heterogeneous mixture of blocks, some of which can only be used for specific purposes. Theses specific purpose blocks, also referred here as hard blocks, include memory, multipliers, adders and DSP blocks etc. Hard blocks are very efficient at implementing specific functions as they are designed optimally

Mar 10, 2022 · FPGAs from Xilinx are hybrid computation systems with Block RAMs, programmable fabric, DSP Slices, and PCI Express support. Just Because all of these compute resources can be accessed at the same time, they enable scalability and pipelining of applications throughout the entire platform.

We review FPGA reconfiguration, looking at architectures built for the purpose, and the properties of modern commercial architectures. We then investigate design flows, and identify the key challenges in making reconfigurable FPGA systems easier to design.

Abstract—In this paper we present the Collaborative Routing Architecture (CRA), a routing architecture specially designed to achieve high efficiency in hardware and competitive delay performance for a FPGA.

Fig. shows how FPGAs evolved from simple arrays of grammable logic and IO blocks to complex heterogeneous multi-die systems with embed-ded block RAMs, digital signal processing (DSP) blocks, cessor subsystems, diverse high-performance external interfaces, system-level inter-connect, and more.

Mar 29, 2011 · We introduce a dynamic dual fixed-point (DDFX) architecture that allows changes in precision (binary point position) based on relatively small changes at runtime in the hardware implementation. Although at a higher reconfiguration time cost, DDFX also allows the dynamic swap between different arithmetic operations.

The programmable logic blocks of FPGAs are called logic blocks or Configurable Logic Blocks(CLBs). • The basic architecture of FPGA consists of an array of logic blocks with programmable row and column interconnecting channels surrounded by programmable I/O blocks as shown in Fig. 9.7.1.

Jul 11, 2015 · A method proposed to ameliorate this overhead is an architecture utilizing localised block RAM (BRAM) connected to the configuration controller to store the configuration bitstream.

Jan 31, 2025 · Figure1 shows the block diagram of the PolarFire FPGA architecture. Your PolarFire FPGA transceiver block has four lanes, supporting data rates ranging from 250 megabits per second to 12.7 gigabits per second.

In this paper, we dis-cuss FPGA implementation of control logic described in an FBD language. We evaluate two approaches: (1) direct conversion from FBD to FPGA hardware using HLS and (2) introduction of an overlay architecture on the FPGA.
