MPC7457 VME 工業用單板電腦
• AltiVec coprocessor for high-performance computational applications
• Two banks of soldered flash memory (32MB and 8MB)
The MVME5500 from SMART Embedded Computing uses the MPC7457 processor running at 1 GHz, balanced with memory, dual independent local buses and I/O subsystems.
The powerful Marvell system controller, with support for a 133 MHz host bus and a 133 MHz SDRAM memory bus, is well matched to the high speed processor.
To match the system I/O to the outstanding processor performance, the MVME5500 provides dual 64-bit, 33/66 MHz PCI buses. Each PCI bus has a PMC site supporting cards running at 33 or 66 MHz. The Universe II VME interface and PMCspan connector are isolated from the PMC sites on a dedicated 33 MHz PCI bus segment so that both PMC sites are capable of 66 MHz operation.
The MVME5500 also offers a Gigabit Ethernet interface, a 10/100BaseTX Ethernet interface and two serial ports. All of this adds up to a set of well-balanced, high-performance subsystems for unparalleled performance.
The MVME5500 series is designed to meet the needs of OEMs including those in defense and aerospace, industrial automation and transportation. Customers looking for a technology refresh for their application while maintaining backward compatibility with their existing VMEbus infrastructure can upgrade to the MVME5500 series and take advantage of the enhanced performance features.
