Pentium computer board fits CompactPCI bus.

Equipped with a 75- or 90-MHz Pentium CPU, the PCIMPU-56 is a 3U Eurocard that is compatible with the emerging CompactPCI-bus standard. The board comes with as many as 32 Mbytes of DRAM or extended-data-out RAM, an SVGA controller, an enhanced IDE-disk controller, and I/O interfaces. You can expand the PCIMPU-56 through its CompactPCI-bus connector, with as many as seven peripheral functions on one CompactPCI backplane. The board includes a 16-bit PC/104 connector and a bridge to a simple 3U Eurocard I/O bus. The PCIMPU-56 runs under Windows 95 and NT, OS/2, Unix, OS-9000, and QNX. Base price is $2500, with a 75-MHz CPU and VGA controller. Gespac, Mesa, AZ. (602) 962-5559.

Debugging package runs under Windows and Unix.

The SingleStep 7.0 debugging environment lets you develop and debug embedded real-time applications on Windows 3.1, 95, and NT and on Unix-hosted platforms. The package includes ANSI C and C++ compilers optimized for embedded designs and a wide range of debuggers that work with the debug ports of various 68000, PowerPC, and ColdFire µPs. A redesigned graphical user interface on both Unix and Windows platforms adds hierarchical list boxes that simplify the display of complex data types, including structures, arrays of structures, and linked lists. The price for a complete package, including a C++ compiler and simulator, starts at $6300 for Unix and $4000 for Windows. Software Development Systems Inc, Oak Brook, IL. (708) 368-0400.

Virtual-reality software includes scene hierarchy.

Release 6 of the WorldTool-Kit, a visual-simulation and virtual-reality-development package, lets you create sophisticated synthetic environments. Release 6 includes >1000 functions and uses a scene-hierarchy description of the visual database to improve performance. You can manage the details displayed in the scene through hierarchical culling, transform information, level-of-detail switching, and instancing. WorldToolKit Release 6 runs on Silicon Graphics, Windows NT, and Internet/World Wide Web platforms. Prices start at $3500. Sense8 Corp, Mill Valley, CA. (415) 331-6318

Performance analyzer enhances ICE operation.

The UEM line of in-circuit emulators (ICEs) now comes with a performance analyzer to give you a comprehensive profile of the real-time behavior of each of the functions in your code. The analyzer nonintrusively measures the minimum, max- imum, and total time each function takes. A field counter accumulates the number of times each function runs. A source-level debugger, which is supplied with the UEM, handles automatic setup of the performance analyzer. Emulator prices range from $5500 to $9000. Softaid Inc, Columbia, MD. (410) 290-7760.

PC interface board works on Data Highway Plus.

The DataLink DL-PC, an ISA-bus card that interfaces with Allen-Bradley networks, operates as a node on Data Highway Plus or as an adapter (virtual rack) on a remote I/O link. The card's serial communications port simplifies connections and lets Allen-Bradley's standard serial drivers (DF1 KE/KF protocol) transfer data at parallel-bus speeds. The DL-PC buffers parallel data, converts it into serial format, and transmits it on the Data Highway Plus or remote I/O link at network speeds as high as 230.4 kbaud. The board costs $750.

Playback module stores phrases in EPROM.

With a resolution of 16 bits and a sampling rate of 8 to 44 kHz, the AudioPro playback device can train simulators or provide voice feedback for remote control. The board stores >4 minutes of speech and sound effects, which can be divided into 512 phrases, in EPROM. You can connect the device through a parallel or serial port. AudioPro, which accepts sound input from various sources, including SoundBlaster VOC files or audio tapes, costs $450. Computer Modules Inc, Santa Clara, CA. (408) 496-1881.

Dual-CPU VMEbus board runs Solaris and VxWorks concurrently.

Equipped with two separate SuperSPARC processor sections, the V264 Predator 6U single-board computer for the VMEbus simultaneously runs under Solaris and VxWorks or dual VxWorks on the same board. The main- and accelerator-processor sections are joined via a high-speed active gateway, which also interfaces with the VMEbus. Each section uses its own SPARC Level II MBus, providing a 64-bit internal datapath with burst transfer rates of 200 Mbytes/sec and sustained transfers >100 Mbytes/sec. Each side of the board has its own DRAM, SRAM, flash memory, I/O facilities, and VME access. You can configure the V264 with a choice of SuperSPARC I or II processors, with prices starting at $4995.

Carrier card for SBC expands PCI bus.

A 6U carrier card for the VMEAlpha64/XP reduced-instruction set single-board com- puter (SBC) accommodates either three PCI mezzanine-card connectors or two PCI mezzanine-card connectors and one PCMCIA card slot. The PMC carrier board supplies a simple mechanism for expanding the I/O of existing embedded applications or for building systems that combine the PCI bus with the VMEbus. The PCI bus handles transfers at 132 Mbytes/sec. The carrier board costs $1275; prices for the VMEAlpha64/XP start at $11,995. Aeon Systems Inc, Albuquerque, NM. (505) 828-9120.
