A field-programmable gate array (FPGA) is a type of configurable integrated circuit that can be repeatedly programmed after manufacturing. FPGAs are a subset of logic devices referred to as programmable logic devices (PLDs).

Jan 20, 2020 · If you want more memory, then you need an off-chip memory on your board. Dev boards typically have an SRAM and/or a SDRAM chip on them, which will offer you 1MB - 32MB of RAM. To talk to them you need an SRAM or an SDRAM controller that knows how to wiggle the lines to write and read data.

Aug 24, 2020 · Designing with FPGAs involves many types of memory, some familiar from other devices, but some that are specific to FPGAs. This how to gives a quick overview of the different flavours, together with their strengths and weaknesses, and some sample designs.

Easy to use, bus attached memory, which can be accessed from FPGA and HPS. There is ONE actual external SDRAM available on this board. Configured as 32 Mwords of 16-bit memory (64 MB)

UltraRAM is a new memory block in UltraScale+ families that enables up to 500 Mb of total on-chip storage, equating to a 6X increase in on-chip memory vs. 28 nm AMD FPGAs.

Block RAMs (or BRAM) stands for Block Random Access Memory. Block RAMs are used for storing large amounts of data inside of your FPGA. They one of four commonly identified components on an FPGA datasheet. The other three are Flip-Flops, Look-Up Tables (LUTs), and Digital Signal Processors (DSPs).

May 8, 2024 · FPGAs also include memory elements, ranging from single-bit flip-flops to very dense memory arrays, for digital data storage within the device. FPGAs are highly valued for their combination of high performance and extreme versatility. They are particularly useful in applications requiring high performance, low latency and real-time flexibility.

FPGAs belong to a class of devices known as programmable logic, or sometimes referred to as programmable hardware. Essentially, an FPGA doesn’t do anything itself but it can be configured to be just about any digital circuit you want. The magic here is that nothing physically changes.

Jan 15, 2025 · These memory interfaces are used to connect to the DDR memory where the data in the host buffers is copied before kernel execution. Each kernel reads data from the DDR memory and writes the results back to the same DDR memory. The memory interface connects to the pins on the FPGA and includes the memory controller logic.

Sep 26, 2013 · When you create a DMA FIFO, it uses two blocks of memory: a small one on the FPGA, and a much larger one on the host computer. The host computer's CPU periodically copies data from the FPGA memory to the host, or vice versa depending on the DMA direction.
