Description
The Motorola MVME167 Single-Board Computer is a high-performance single-board computer in a CISC-based system. Motorola's MVME167P single-board computer represents the functionality, flexibility, and performance of a CISC-based system. Based on the Motorola MC68040, the MVME167P combines a microprocessor with the memory management and floating-point units. This outstanding processing speed and floating-point performance makes the MVME167P an ideal solution for scientific and industrial applications. The inclusion of the new "Petra" application-specific integrated circuit (ASIC), which replaces functions formerly implemented in the MCECC chip, improves the performance of the memory subsystem. Memory configuration switches enable the customer to tailor memory size for applications requiring smaller memory configurations. The MVME167P's compatibility with existing M68000 family software offers CISC-based software environments the ability to realize near-RISC performance levels while maintaining object code compatibility with existing software platforms. Configuration: • 33 MHz MC68040 Microprocessor with Floating-Point Coprocessor • 8 MB ECC DRAM • No BIOS Chips Installed
Embedded microprocessors Embedded cpus present a colorful scene compared with general-purpose cpus, and there are more than 100 kinds of 32-bit embedded cpus in the world alone. Embedded CPU mostly works in the system designed by specific user groups, which has the characteristics of low power consumption, small size and high integration, which is conducive to the design of embedded controller tends to be miniaturized, intelligent and closely integrated with network applications. Embedded operating system Now the more popular Embedded operating systems in the world are: Microware OS9, Sun Java OS, Microsoft Windows CE, Windows NT Embedded, free software RT-Linux and so on. China's Kais Group has also developed a general embedded operating system Hopen with independent intellectual property rights. Network interface Network interface provides the necessary conditions for embedded controller to access network. The network interface takes 32-bit CPU as the center, the controller completes the control function of the network interface, the communication interface has RS 232C serial interface, communication protocol repeater interface, network interface and so on. The Ethernet control network can be constructed by using embedded controller and network interface. With the support of distributed network computing platform, distributed control network can also be built. Technical essentials The operating system platform and network communication platform of embedded controller are popular open platforms in the world, which lays the foundation for the openness of Ethernet control network. The operating system platform of embedded controller, such as RT-Linux, has strong function, and the application software development is fast and convenient. The application software developed on the Linux operating system can run directly in the RT-Linux environment, that is, the development of embedded controller application software does not need special software development systems and tools. The powerful embedded CPU provides the embedded controller with high performance, high speed processing power and flexible expansion mode. Support TCP/IP protocol, easy to achieve network interconnection and network expansion. Various networks can be used as embedded controllers to access the backbone network. These backbone networks have high communication speed, good real-time performance, and support distributed network computing to achieve network collaboration. Embedded controller, network interface and distributed network computing platform can not only build open and powerful Ethernet control network, but also realize seamless integration of control network and information network.
