Description

IC-xe6-XMCa is powered either by a MPC8641 or a MPC8641D (Dual core version). It uses e600 core(s)(formerly G4) and high-speed interconnect technology to balance processor performance with I/O system throughput. Each core is a high performance supercalar design supporting multiple execution units. Each e600 core includes 32-Kbyte separate I/D L1 caches and a 1-Mbyte L2 cache.

IC-xe6-XMCa implements two independent DDR2-ECC banks with a capacity of up to 1-Gbytes each. The integration of the system controller provides spectacular memory bandwidth and memory latency performances. The MPC 864& on-chip MPX bus operates four times faster than the external MPX bus implemented on our MPC7448 and Discovery CPU.

To facilitate SMP or AMP OS implementation, the system controller provides an optional low-memory address offset mode between the dual cores, allowing each processor to see a distinct and private physical address space. Private address space can be allocated to the cores without any special software involvement.

IC-xe6-XMCa can be used as a PrPMC or a XMC board. In PMC mode, it provides a 64-bit PCI or PCI-X bus interface. In XMC mode through Pn5, PCI-E x4 or SRIO x4 can be used as serial bus interface. The board is configurable in Monarch or non-Monarch mode.

IC-xe6-XMCa integrates many communication functions : three Giga Ethernet channels with enhanced MAC controllers, two UART ports, etc.

IC-xe6-XMCa provides a large capacity of Nor Flash andNandFlash useful to implement huge Linux file systems.

IC-xe6-XMCa can be configured with MPC8641-LV or 8641D-LV processor. The power consumption exceeds 20W for the dual core version.
The PMC standard configuration is not set up with the XMC connector.

IC-xe6-XMCa on-board firmware

The basic firmware takes in charge Freescale’s new MPC8641 (D) and its on-board system controller 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 with its system controller, performs a comprehensive Power-on self-tests (PBIT), before to jump in different applications according to the values stored in memory. If the board acts as a Monarch PMC, the software executes a enumeration step, otherwise it waits 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 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’s access to the specific IC-xe6-XMCa 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, serial ports, MAC driver for Gigabit ports.

Interface Concept provides BSP for VxWorks® (6.x) or Linux from Windriver and Linux 2.6.x for ICLinux SDK (Linux distribution from IC). Other RTOS (Integrity, LynxOS,...) can be ported on request.
