基于奔腾 III 处理器的

VME 单板计算机奔腾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。VMIVME7750-234GE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。

奔腾III处理器与早期的Pentium II非常相似，但最值得注意的不同是SSE指令的扩充，以及在每个芯片制造的过程中加入了有争议的序号。此外，Pentium III处理器还包含了70条SIMD指令，VMIVME7750-234GE显著增强了多媒体和视频流应用的性能。同时，它还具有先进的高速缓存技术，加速了信息从系统总线到处理器的传输，从而大幅提升了性能。

VME single-board computer based on Pentium III processor

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 control unit in the VMIVME7750-234GE processor module is the command and control center of the whole CPU, which is composed of the instruction register, the instruction decoder and the operation controller, etc., which is extremely important to coordinate the orderly work of the whole 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.

The Pentium III processor was very similar to the earlier Pentium II, but the most notable difference was the expansion of the SSE instructions and the inclusion of controversial serial numbers in each chip manufacturing process. In addition, the Pentium III processor includes 70 SIMD instructions, and the VMIVME7750-234GE significantly enhances the performance of multimedia and video streaming applications. At the same time, it also has advanced caching technology that speeds up the transfer of information from the system bus to the processor, which greatly improves performance.
