Embedded Systems Design Europe - November 2007 - (Page 41) new products Memory modules make use of flash technology The M222 series of high-density, low power consumption, mass storage modules with DMA controller providing up to 64Gbyte of flash memory in an industry standard PMC slot from Aitech Defense Systems is available through Diamond Point International. Designed for high-speed read, write and erase performance, the M222 modules has memory in two arrays with parallel access. Each array comprises eight 8-bit wide devices arranged in parallel to form a 64bit wide port. Each array can host single, dual or quad bank flash devices with flash densities of 8, 16, 32 and 64Gbyte are available. Available in commercial, rugged and military grade configurations, the M222 modules are designed to resist shock and vibration for the reliability in the most demanding applications. The modules are suited to such applications as storage and control of software programmable Electronic Signals Intelligence (ELINT) data, high-density local radar or sonar images and other advanced graphics environments. The M222 family of modules integrate thermal heatsinks which allow optimal heat transfer to the enclosure’s sidewalls. They are available from Diamond Point in forced air-cooled and standard ANSI/VITA 20 conduction-cooled mechanical formats. Both versions are single slot PMC of master/target operation on the PCI bus. It supports 66MHz/64-bit data transfers on the PCI side and a 66MHz/32-bit local bus. The modules are capable of providing sustained data transfer rates of up to 130Mbyte per second when DMA transfer mode is used with a fast host interface. In this mode the M222’s PCI Rev. 2.3 compliant interface is implemented using the onboard PLX PC9656 PCI to local bus bridge. The modules are provided with Aitech’s flash low level (FLL) driver for VxWorks real-time operating system (RTOS). In addition to supporting all basic read/ write/erase operations, the FLL provides error detection for the mapping and marking of bad blocks, write protection and a parallel bank writing option for enhanced performance. Integrity RTOS support is provided via a WLFS2 low-level driver to connect the M222 hardware to standard Integrity file systems. Integrity’s higher level FSS file system can also be mounted on the WLFS2 system. www.dpie.com modules that connect and take all of their power from the CompactPCI, VMEbus or PCI base board. The power consumption of the M222 at a typical throughput of 45Mbyte per second is 7 W. The M222 family is capable Debug tool supports the STM32F10x Cortex-M3 iSYSTEM has developed a debug tool support for the STM32F10x Cortex-M3 device from STMicroelectronics. Debugging is based on JTAG or single wire debug communication with a target application and the debugger connects to the host PC via a standard USB interface. An integrated development environment and software debugger is included. For Cortex-M3 devices that include on-chip trace (like the STM32F10x), this functionality is supported too. The tool also supports highspeed flash programming. The debugger software, a native 32-bit Windows application, operates under all popular versions of Windows, including NT, 2000, XP and Vista. It integrates seamlessly with a variety of C/C++ compilers. www.isystem.com www.embedded.com/europe | embedded systems design europe | NOVEMBER – DECEMBER 2007 41 041_ESDE.indd 41 8/11/07 13:32:54 http://www.dpie.com http://www.isystem.com http://www.embedded.com/europe
