Description

IC-e6-VMEa is powered by a MPC7448, being part of the PowerPC processor family. This processor features a high-frequency super scalar PowerPC core capable of issuing four instructions per clock cycle into 11 independent execution units : four integer units, one double-precision floating point unit, four Altivec units, load/store and branch processing units. The MPC7448 provides 3900 DMIPS @ 1,7GHz. Owing to the Dynamic Frequency Switching, the core frequency can be changed “on the fly” to reduce the power consumption.

IC-e6-VMEa runs as a system controller or standard board. An automatic detection can be used with the VME64x backplane. The VMEbus interface is based on a combination of the Tundra Tsi148 VME bridge and the latest generation of Texas Instrument transceivers. This design allows the switching speed required by the 2eSST protocol on all the backplane slots.

IC-e6-VMEa implements a Discovery^TMIII chipset to fill out the processor. This solution includes major enhancements such as : data streaming on MPX bus, read memory latency and cache coherency improvements. The MV64460 indeed, adds 2 Mbits of high speed burst SRAM, two XOR DMA (useful for RAID, iSCSI) and four IDMA engines.

IC-e6-VMEa integrates many communication functions : three Giga Ethernet channels, one console port. An USB2 controller combined with a hub function provides three high/full speed ports. A quad UART provides four additional asynchronous channels available on P2.

The 64-bit PCI/PCI-X bridge allows the IC-e6-VMEa to control two PMC mezzanine boards.
Thanks to its SAS/SATA controller, IC-e6-VMEa can manage directly several storage devices.

IC-e6-VMEa can be used with many major RTOS and Linux.

IC-e6-VMEa on-board firmware

Our basic firmware takes in charge Freescale’s new MPC7448 and the Marvell chipset DiscoveryIII initialization. This on-board firmware, based on the open-source UBOOT, is a comprehensive set of software stored in a secured flash.

UBoot

It is called by the reset vector when the board is powered up. It initializes the PowerPC and the Discovery^TMIII system controller, performs a comprehensive Power-on self-tests (PBIT), before jumping into different applications according to the values stored in memory. If the board acts as a Monarch PMC, the software executes an enumeration step, otherwise it waits for the PCI startup sequence from the host. In standalone mode the board directly runs the configured application.

The firmware allows loading files from Ethernet via Bootp, running files in RAM or flashing them. In addition, it allows some monitor functions such as : display or modify the RAM data. To end with, it enables the user to perform maintenance tests.

IC_Bios

This module allows the user to access the specific IC-e6-VMEa hardware resources via an easy-to-use API. This module is used as a library with Vxworks and as a dynamically loaded library module for Linux.

IC-BSP basic

These BSPs products are based on the standard distribution of the OS editor. They take in charge hardware initialization, interrupt handling and generation, hardware clock and timer services, memory management, PCI management, mapping of memory spaces, serial ports, MAC driver for Gigabit ports.

Interface Concept provides BSP for VxWorks® and Linux® operating systems. Other RTOS (LynxOS, Integrity...) can be ported on request.
