YPP110A 3ASD573001A1 驱动数字处理器模块

产品详情：

CPU YPP110A 3ASD573001A1大致可分为如下八个逻辑单元：

（1）指令寄存器 ：YPP110A 3ASD573001A1是芯片上的指令仓库，有了它CPU就不必停下来查找计算机内存中的指令，从而大幅提高了CPU的运算速度。

（2）指令译码器 ：YPP110A 3ASD573001A1负责将复杂的机器语言指令解译成运算逻辑单元（ALU）和寄存器能够理解的简单格式，就像一位外交官。

（3）控制单元 ：既然指令可以存入CPU，而且有相应指令来完成运算前的准备工作，背后自然有一个扮演推动作用的角色——它便是负责整个处理过程的操作控制器。根据来自译码单元的指令，它会生成控制信号，告诉运算逻辑单元（ALU）和寄存器如何运算、对什么进行运算以及对结果进行怎样的处理。

（4）寄存器 ：YPP110A 3ASD573001A1对于CPU来说非常的重要，除了存放程序的部分指令，它还负责存储指针跳转信息以及循环操作命令，是运算逻辑单元（ALU）为完成控制单元请求的任务所使用的数据的小型存储区域，其数据来源可以是高速缓存、内存、控制单元中的任何一个。

CPU YPP110A 3ASD573001A1 can be divided into the following eight logical units:

(1) Instruction register: YPP110A 3ASD573001A1 is the instruction warehouse on the chip, with which the CPU does not have to stop to find the instructions in the computer memory, thus greatly improving the CPU's computing speed.

(2) Instruction decoder: YPP110A 3ASD573001A1 is responsible for interpreting complex machine language instructions into simple formats that can be understood by ALUs and registers, just like a diplomat.

(3) Control unit: Since instructions can be stored in CPU, and there are corresponding instructions to complete the preparatory work before calculation, there is naturally a driving role behind it -- it is responsible for the whole process of operation controller. Based on instructions from the decoding unit, it generates control signals that tell the operational logic unit (ALU) and registers how to operate, what to operate on, and what to do with the result.

(4) Register: YPP110A 3ASD573001A1 is very important for CPU. In addition to storing part of the instructions of the program, it is also responsible for storing pointer jump information and cyclic operation commands. It is a small storage area for the data used by the ALU to complete the tasks requested by the control unit. Its data source can be any one of the cache, memory, or control units.
