数字IC设计中,单端口RAM、伪双端口RAM和真双端口RAM各有特点。单端口RAM只能同时读写,伪双端口RAM可并行读写但仅A写B读,真双端口RAM可同时读写且互不干扰。文章还介绍FIFO与伪双端口RAM的区别及存储器深度、宽度概念,并给出Verilog代码与仿真结果。
FPGA(Field Programmable Gate Array)是一种可编程逻辑器件,具有可重构性、高速度、低功耗等特点,被广泛应用于数字电路设计、信号处理、图像处理等领域。在FPGA中,实现各类存储器是非常重要的任务之一。存储器是计算机系统中的重要组成部分,用于存储程序和数据。在FPGA中,存储器包括RAM(Random Access Memory)、SRAM(Stat...

BRAM 也可以做成 ROM,典型应用是:Program code storage, initialization ROM,如下图所示 与Single-port RAM 几乎相同,唯一不同的是,没有 DINA 信号,因为是 ROM,所有不提供写入; Dual-port ROM BRAM 也可以做成 ROM,典型应用是:Single ROM shared between two processors/systems ...
As you know, in Verilog, initialize $readmemh code is initialized Ram simply. I searched a VHDL code like this but i can't get. Do you help me to find this code? If you know a sample, can you share with me ? Thanks. Translate ...
