Block Memory Generator

Overview

Product Description

Xilinx provides a flexible Block Memory Generator core to create compact, high-performance memories running at up to 450 MHz

The Block Memory Generator LogiCORE™ IP core automates the creation of resource and power optimized block memories for Xilinx FPGAs. Available through the (add ref to Vivado®) ISE® Design Suite CORE Generator™ System, the core enables users to create block memory functions to suit a variety of requirements. Built-in knowledge about Xilinx device architectures allow it to leverage specialized FPGA architectural features to create the most compact, high performance or low power solution.

A Migration Kit is available to automate the migration to latest version of the core.
