High-performance VMEbus board uses superscalar chip
Single-board computer achieves over 70 SPECmark89 at 50 MHz
Designed around the company's 50-MHz 88110 symmetric superscalar RISC
processor, the MVME197 single-board computer (SBC) achieves a performance
level of over 70 SPECmark89. The board is targeted at OEMs and system
integrators in compute-intensive applications like simulation, real-time
complex I/O, and telecommunications. Communications on the '197 is via a
SCSI interface with 32-bit local-bus DMA, an Ethernet interface with
built-in DMA controller and 32-bit local bus interface, a printer port,
and four serial ports. An optimized VME D64-compatible interface is
capable of data transfers exceeding 40 Mbytes/s. A BusSwitch converts the
local peripheral's 32-bit data bus to the 88110's 64-bit system. This
allows existing MC68040 peripherals to work with the board. To solve the
problem of getting data to the processor fast enough, the MVME197 uses a
memory architecture that supports burst data transfers and provides error
checking and correction. Sustained burst transfers as fast as 3/1/1/1
cycles are possible between the 88110 and main memory. The high level of
functionality has been achieved through the use of six custom ASICs. The
use of ASICs also lowers power consumption and increases reliability
through reduced component count. Along with other third-party software,
the MVME197 is supported by Motorola's Unix System V/88 Release 4.0. This
is an enhanced implementation of Unix System Laboratories Unix System V. The
board is available in sample quantities now, with volume shipments
beginning in December. ($9,995–3 to 4 weeks ARO.) Motorola, Inc.,
