FSMC(Flexible Static Memory Controller)是一种用于控制静态存储器(如SRAM、NOR Flash等)的微控制器外设。它主要负责将处理器的数据、地址和控制信号转换成存储器所需的信号。通俗地说,就是FSMC可以让微控制器与静态存储器进行高效的数据交换。
当处理器需要从静态存储器中读取数据时,它会向FSMC发送一个读取请求,并传递所需的地址。FSMC会根据地址计算出实际的存储器地址,并向存储器发送读取信号。一旦存储器准备好数据,它会将数据传回FSMC,FSMC再将数据传递给处理器。
同样的,当处理器需要向静态存储器写入数据时,它会向FSMC发送一个写入请求,并传递要写入的数据和地址。FSMC会将数据写入存储器,并进行必要的校验和纠错。
总之,FSMC是一个非常重要的外设,它可以使微控制器与静态存储器之间的数据交换更加高效、可靠。

Verilog FSMC (Finite State Machine Controller) is a type of digital design that is used to control the operation of a finite state machine. It is a hardware design language used in the design and verification of digital circuits. The FSMC is used to describe the behavior of a digital circuit, and it can be used to design a wide range of digital systems, including microcontrollers, processors, and memory controllers.
The Verilog FSMC is used to define the state transitions of the finite state machine. The FSMC can be represented as a set of states, where each state represents a different behavior of the system. The FSMC can be used to control the operation of the digital circuit by specifying the state transitions that occur based on inputs and outputs.
The FSMC is implemented using sequential logic, which means that it is designed to store and maintain state information. This allows the FSMC to respond to input signals and generate the appropriate output signals based on the current state of the system.
In summary, Verilog FSMC is a powerful digital design tool that can be used to create complex digital systems. It is widely used in the electronics industry and is an essential part of many digital design projects.
