VMIVME-7765  奔腾 III 处理器  用来控制各种总线

VMIVME-7765-540 VME SBC 处理器模块

VMIVME-7765-540：

• 处理器：1.26 GHz 奔腾 III 处理器 （FC-PGA2）

• 内存：2 GB

• 闪存：无

奔腾III（Pentium III）是英特尔的x86（更准确地说是i686）架构之微处理器，于1999年2月26日推出。该处理器最初发布了Pentium III 450MHz和Pentium III 500MHz的版本，它们采用了0.25微米工艺技术，核心由950万个晶体管组成。

VMIVME-7765-540处理器模块通常由微处理器、缓存、总线控制器、数据通路和控制单元等组成。其中，微处理器负责执行各种计算和操作，缓存存储了CPU模块需要的数据和指令，总线控制器用来控制各种总线，数据通路则负责把数据从内存中传送到CPU模块。

此外，VMIVME-7765-540处理器模块中的控制单元是整个CPU的指挥控制中心，由指令寄存器、指令译码器和操作控制器等组成，对协调整个电脑有序工作极为重要。它根据用户预先编好的程序，依次从存储器中取出各条指令，放在指令寄存器中，通过指令译码确定应该进行什么操作，然后通过操作控制器，按确定的时序，向相应的部件发出微操作控制信号。

VMIVME-7765-540:

• Processor: 1.26 GHz Pentium III processor (FC-PGA2)

• Memory: 2 GB

• Flash memory: None

The Pentium III is an x86 (more accurately i686) microprocessor from Intel, introduced on February 26, 1999. The processor was initially released in Pentium III 450MHz and Pentium III 500MHz versions, which used 0.25 micron process technology with a core consisting of 9.5 million transistors.

The VMIVME-7765-540 processor module is usually composed of a microprocessor, cache, bus controller, data path and control unit. Among them, the microprocessor is responsible for performing various calculations and operations, the cache stores the data and instructions needed by the CPU module, the bus controller is used to control various buses, and the data path is responsible for transmitting data from the memory to the CPU module.

In addition, the control unit in the VMIVME-7765-540 processor module is the command and control center of the entire CPU, which is composed of instruction registers, instruction decoders and operation controllers, etc., which is extremely important to coordinate the orderly work of the entire computer. According to the user's pre-programmed program, it takes out each instruction from the memory in turn, puts it in the instruction register, determines what operation should be carried out through the instruction decoding, and then sends a microoperation control signal to the corresponding component by operating the controller according to the determined timing.
