Description

IC-e6-cPCIb is powered by one or two MPC7448 (optionally MPC7447A), being part of the PowerPC processor family. This processor features a high-frequency superscalar 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.

The dual processor version runs with SMP Linux (Symmetrical multi Processor).

IC-e6-cPCIb runs as a host system controller or a peripheral board with an automatic slot detection. The PCI interface runs up to 66MHz in PCI mode and up to 133MHz in PCI-X mode. A second PCI/PCI-X bridge controls two PMC mezzanine cards.

IC-e6-cPCIb 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-cPCIb integrates many communication functions : three Giga Ethernet channels, one console port. An USB2 controller provides three high/full speed ports. A quad UART provides four additional asynchronous channels.

Thanks to its optional SATA controller, IC-e6-cPCIb can directly manage several storage devices.

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

IC-e6-cPCIb on-board firmware

Our basic firmware takes in charge Freescale’s new MPC7448 or the MPC7447A and the Marvell chipset Discovery III initialization. This on-board firmware, based on the open-source UBOOT, is an efficient 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-cPCIb 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.. The dual processor model runs LINUX SMP.
