This specification allowed for an inter-operable, conduction-cooled, mechanical form-factor VMEbus board to be used in rugged and harsh environment aerospace and defense systems. Look for DY 4 to continue pushing the envelope.

ACCOMPLISHMENTS TI BESTOWS AWARD ON DY 4 For the third consecutive year DY 4 was presented with the 'Texas Instruments, Supplier Excellence Award', with an exceptional rating of 96%. Some of the criteria on which DY 4 was judged included quality of product, management quality, product or process disruptions (or lack of), on-time delivery, flexibility of schedule, pricing strategy, and customer service practices.

CONTRACTS DY 4 is about to begin work on a 'ship lift system', for a prominent submarine manufacturer. The system is to be used when the subs are lifted out of the water, and reliability is essential since the subs carry nuclear reactors.

Another notable company has chosen DY 4 over stiff competition to supply cards for a helicopter landing system which is to be installed in a hanger on a ship deck. Environmental conditions were harsh, due temperature and salt fog, yet a specially screened, conformally coated level 100 product was chosen.

ON THE HORIZON Look for DY 4 Systems to be included on the VITA Home Page of the World Wide Web. Wilf Sullivan, Product Manager of Systems and S/W at DY 4, has written a Technical Bulletin on the Power PC 603 and its real-time performance. It will soon be published in COMPUTER DESIGN MAGAZINE.

  DY 4 Systems Inc. and Spectron announce SPOX support for the SVME/DMV 442 Quad C40 Digital Signal Processing Card.

  For customers who build and develop real-time embedded DSP systems: DY 4 is the only VME vendor to provide a completely seamless, full system solution for commercial and harsh environment applications. DY 4's DSPs and Single Board Computers (SBCs), together with SPOX and VxWorks, provide the DSP systems developer with an integrate-with-ease solution.

  Now DY 4 Systems allows DSP applications developers to choose a complete, off-the-shelf solution to help them meet shrinking time-to-market deadlines. DSP applications are increasing in complexity; and pressure is growing to produce more, faster. To enhance productivity for combined hardware/software systems, DY 4 has ported SPOX, a software development environment for DSP applications, to SVME/DMV 442 Quad C40-based DSP boards. 'SPOX is an excellent complement to the DY 4 DSP product line. It's recognized by our customers as a quality product and is a good match for their embedded application development requirements, ' says Wilf Sullivan, Product Manager of Systems and Software.

  DY 4's proven DMV-442 packs four TI TMS320C40 Digital Signal Processors on a single 6U VME board, achieving a combined performance of 160 million floating point operations per second (MFLOPS). Each processor has a speed of 40 MHz, dual memory buses, and private memory of up to 4M bytes of fast static RAM. Global memory of upto 2M bytes of SRAM is accessible by all the C40's, allowing for processors to share data. In multiple DMV-442 systems up to four ports are accessible for inter-connection to other C40's. External processors on the VMEbus can send messages to any of the local C40's through a unique inter-processor mailbox interrupt mechanism, providing an efficient interrupt-driven communication.

  The combined global memory, communications ports, and mailbox interrupts provide the DMV-442 with flexible, high bandwidth, inter-process data communications which are critical to real-time signal processing applications. VME64TM block transfers are supported. The DMV-442 has an optional high speed Image Bus interface with a 50M byte/sec channel to other processing modules, suitable for building large systems with many sensors and signal processors. DY 4 has chosen SPOX, a deterministic, real-time, multi-tasking kernel, specifically designed for DSP architecture, to provide a real-time software development environment for the 442. SPOX offers a large body of software components which can be tailored to suit a customer's needs. Both compact and flexible, SPOX provides inter-operability between the host system and DY 4's DMV-442, enhancing the ability for VME-based systems designers to build applications such as radar and sonar processing, video image enhancement, target recognition, audio/speech processing, and embedded wireless communications.

  SPOX provides support tools such as debuggers, configuration tools, and high-level language compilers. Product support in the SPOX environment consists of SPOX-KNL, SPOX-MATH, SPOX-DBUG, and SPOX-LINK; a suite of software modules created to provide communication between a DSP to host computer. John Wemekamp, Director of Marketing and Technology at DY 4 Systems, says, 'From a systems point of view, SPOX-Link coupled with operating systems such as Wind River System's VxWorks provides a complete software solution for the full DY 4 VMEbus product line.' All four subsystems are implemented as libraries of C-callable modules. Designers simply select the library modules required for their application, compile them, and link them with their main application.

  HIGHLIGHTS Seamless movement across multiple CPUs can be achieved with SPOX. The encapsulation of hardware specifics in device drivers makes it truly hardware independent, ensuring that applications port easily to new architectures or scale up to larger system configurations. Once an application has been developed and debugged on a single CPU system it can be integrated into a real-time embedded system without modifying the source code.

  Unlike conventional real-time operating systems, SPOX has been optimized specifically to address the compute, interrupt handling, I/O, and memory management needs of DSP applications. Key features include:

  • Deterministic, preemptive, real-time multitasking with multiple

  priority levels.

  • High-speed interrupt processing, exception handling and timer

  services.

  • Mailbox services for task-to-task synchronization and

  communication.

  • Semaphores and queues for task and interrupt communication and

  synchronization.

  • Predictable, high-speed, device independent streaming I/O.
  • DSP-optimized memory management facilities with dynamic memory

  allocation and support for multiple memory segments.

  According to Spectron's Market Programs Manager, Bruce Thompson, 'SPOX offers a number of facilities that are ideal for the SVME/DMV 442's multiprocessor C40 architecture. Among these are a single-CPU programming model that makes it easy to develop applications on one DSP, and then move them to multiple DSPs;

  comm port drivers that are optimized for high-speed point-to-point communications between DSPs, and a floodfill loader that makes it easy to distribute applications across multiple DSPs at boot time.' Added Thompson, 'SPOX-LINK'S high-speed streaming I/O facilities should also prove ideal for establishing efficient VMEbus communications between DY 4 VxWorks-based host controllers and SPOX-based SVME/DMV targets.'V targets.'

  DY 4 recently released the first in a new family of Motorola PowerPC-based SBCs: the SVME/DMV-170 VMEbus Single Board Computer. It can replace as many as three previous-generation VME cards by combining a high-performance 66 MHz PowerPCTM 603 RISC processor or 100 MHz 603e with up to 12 Mbytes of SRAM and 4 Mbytes of FLASH EPROM all on a single-slot assembly.

  To enhance I/O support, the MAXPack I/O mezzanine interface allows for the addition of daughter-card modules such as MIL-STD-1553B, and on-card interfaces including Ethernet, SCSI-2 and Serial I/O. The 170 comes in air- and conduction-cooled commercial, rugged and military versions, all fully software-compatible.

  Comprehensive software support guarantees easy application migration between all versions, and from other processors including DY 4's 680x0 processor cards. It supports VxWorks real-time operating systems with drivers for both on-card I/O devices and allows for interfacing with other DY 4 communications controllers and graphics controllers. Also, Ada Board Support Packages for the SVME/DMV-170 allow for Ada- based applications on the Power PC.

  DY 4 Brings X-Windows to MIL VME

  DY 4 Systems Inc. announced today it is bringing X-Windows to military systems with the introduction of DX-Windows, the first high-performance X-Windows System Server for military VME applications. DX-Windows allows MIL developers to draw on the wealth of existing UNIX software in the X-Windows environment, including GUI builders and other time-saving tools.

  DY 4 has optimized DX-Windows for use with the DY 4 SVME/DMV-770 high performance color Graphics Display Controller (GDC), already available in off-the-shelf commercial, rugged, and military formats. This optimization allows applications to access multimedia capabilities, including live video, image processing and target tracking.

  The Power of Open Systems:

  Widely used for commercial GUI development, X-Windows allows VMEbus application developers to reduce costs and time-to-market by drawing on the benefits of an open system, including:

  • a large base of third party software and expertise
  • true hardware independence, with code re-use across platforms
  • ability to prototype application interfaces on workstations,

  with easy migration to an embedded target.

  The hose-based component of the DX-Windows Server is available with the VxWorks real-time operating system and can be ported to other operating systems. DX-Windows is compatible with leading third-party software, including Visicom's VX-Windows, Xlib, and OSF/Motif.

  Highest Performance Available:

  DY 4's DX-Windows Serveris split between the DMV/SVME-770 GDC and a choice of host DY 4 Single Board Computers (SBC's). The TMS34020-based GDC graphics engine is dedicated to server display and control of mouse and keyboard, while the host SBC provides the Application Program Interface (API). This separation of X-Client application from graphics processing gives DX-Windows much higher performance than SBC-based servers that use the graphics card merely as a dumb frame buffer.

  DX-Windows supports local X-Client executing on the host SBC, X-Clients executing on other processors on the VMEbus, and remote X-Clients using the DX-Windows LAN capabilities.

  Multimedia Solution:

  With DY 4's DMV/SVME-674 frame-grabber card and 770 GDC, applications can access multimedia capabilities as part of the DX-Windows display, notably live video, electronic imaging processing, and target tracking. To control 674 live video in an X-Window environment DY 4 has created X-Client libraries.

  Pricing for DX-Windows starts at $2, 600. Available today, off-the-shelf.
