RadiSys announces EPC-43 compact Pentium processor-based computer for embedded multimedia, networking applications; On-board RadiSys EPM-1 embedded processor module offers upgradeability, long life.

HILLSBORO, Ore.--(BUSINESS WIRE)--April 29, 1997--RadiSys Corp. (NASDAQ:RSYS) today announced the EPC-43(R) embedded computer with the RadiSys EPM-1 Pentium(a) processor-based Embedded Processor Module.

The EPC-43 is the first integrated computer that combines multimedia interfaces and powerful processing capabilities with a very small foot-print for embedded applications where space is at a premium, such as interactive point-of-sale terminals, medical instruments and factory network hubs.

The EPC-43 consists of the EPM-1, which contains the processor/chipset core of the computer, and the I/O functionality that is contained on a special baseboard. This design isolates the target I/O from the high speed circuitry associated with Pentium processors and ensures the long-life of the product by allowing the designer to upgrade the I/O baseboard with a faster processor module.

For instance, if the application develops to become more graphics-intensive, an EPC-43 with a 100-, 133- or 166MHz Pentium processor can be upgraded to a 200MHz MMX processor module with no other change to the design.

"The EPC-43 is a compact, stand-alone computer for embedded applications that require high performance graphics, networking or computation deeply integrated into the OEM's end product," said Charlie Crawford, director of marketing for RadiSys' Integrated Products Division. "The combination of the Pentium processor and powerful I/O baseboard make it particularly suitable where multimedia functionality and fast throughput are necessary."

EPC-43 features

The EPC-43 with the EPM-1 is a fully configured PC, including 10/100 BaseT Ethernet, CardBus interface, Sound Blaster compatible sound support, two USBs, four serial ports, one parallel port, on-board application flash, floppy, hard disk, and CD drive interfaces plus PCI and PC104 bus expansion capabilities.

The EPM-1 is a compact, integrated 4.2" x 5.3" (107 x 135mm) Pentium processor-based CPU board that is available with a choice of 100MHz STD, 133MHz VRT, 166MHz VRE or 200MHz MMX Pentium processor. EPM-1 has all the essential elements of the core of a computer, including the Intel 430HX chipset with the PIIX PCI/ISA accelerator, SODIMM sockets accommodating up to 256MB of DRAM, 82C42PE keyboard/mouse controller, processor power supply, L2 cache memory, Real Time Clock (RTC), battery backed CMOS RAM and clock synthesizer, and flash-based configurable Phoenix BIOS.

To facilitate customers' hardware and software evaluation and development cycle, RadiSys has created the EPC-43-DEV development kit, which includes an open chassis, circuit diagrams and other comprehensive documentation. The Phoenix OEM Adaptation Kit (OAK) is available as an option with the EPC-43-DEV so customers can customize the BIOS for their application.
