本篇文档主要介绍了寄存器文件结构,具体介绍了创建读取端口、创建写端口、主存、SRAM的典型大小、用4片8K x 1 bit 的 RAM 连接成32K x 1 bit 的RAM 、 用 32K x 1 bit 的RAM 连接成32Kx 4 bit RAM。

1 .Register file construction Creating read ports

2 .Creating write port

3 .Main Memory Address Processor MEMORY write Data in Data out read Memory ROM (Read only memory) RAM (Random Access Memory) SRAM (cache memory) DRAM (Main memory)

4 .Typical sizes of SRAM are (32 or 64 or 128 or 256) x (1 or 2 or 4 or 8 bits) address chip select SRAM output enable data out 32K x 8 bits write enable data in How many lines are there in address, data in and data out?

5 .

6 .32K x 1 bit RAM using 4 8K x 1 RAMs Data in A12-A0 addr 00 CE 01 in A14-A13 10 addr 11 CE 2-4 in decoder addr CE in addr CE in Data out For each chip, the write enable line is set to 1 during a write operation, and the output enable lines are set to 1 during a read operation.

7 .32Kx 4 bit RAM using 32K x 1 bit RAMs Data in A14-A0 Addr Addr Addr Addr out out in in out out in in Data out For each chip, the write enable line is set to 1 during a write operation, and the output enable lines are set to 1 during a read operation.
