The MOTOROLA MVME5500 is a high – performance single – board computer in the MVME series, designed for applications that require reliable and powerful computing in harsh industrial environments5. It adopts the advanced PowerPC architecture with high – performance processors such as the MPC7455 or MPC7457, running at a main frequency of up to 1 GHz, which is suitable for data – intensive applications2.

This module features a large – capacity memory, supporting up to 2 GB of DDR SDRAM, and also has built – in flash storage of up to 64 GB6. It provides a balanced performance from the processor, memory, dual – independent local buses, and I/O subsystems1. The powerful Marvell system controller supports a 133 MHz host bus and a 133 MHz SDRAM memory bus, matching the high – speed processor perfectly1. In addition, it is equipped with dual 64 – bit, 33/66 MHz PCI buses, and each PCI bus has a PMC site, which can support cards running at 33 or 66 MHz1.

The MVME5500 also offers a Gigabit Ethernet interface, a 10/100BaseTX Ethernet interface, and two serial ports1. It supports a variety of real – time operating systems, such as VxWorks, Linux, and Windows CE, and has good compatibility and scalability2.
