Motorola Announces First High Performance
Single Board Computer Using Superscalar Chip

TEMPE, Ariz., August 3, 1992 -- The MotorolaR Computer Group today 
announced the availability of a new high performance single board 
computer (SBC) based on the company's 88110 Symmetric SuperscalarTM 
reduced instruction set computer (RISC) microprocessor. The new 
MVME197 SBC is a highly integrated module designed to utilize the 
full power of the 50 MHz 88110 microprocessor. The MVME197 offers 
maximum 88110 performance without sacrificing the functionality or 
flexibility of a single board computer. It is aimed at OEMs and 
systems integrators in the simulation, telecommunications, and 
other markets requiring compute-intensive applications and a 
variety of connectivity requirements including FDDI, EthernetTM, 
SCSI, and graphics.

The MVME197 will be shown to the public for the first time 
at BUSCON/ East, Sept. 15-17. The conference and exhibition are 
being held in the Hynes Convention Center. TSD's booth is #705.

The MVME197 provides users with the highest performance and 
functionality available on a VMEbus-based single board computer. 
Simulated SPEC benchmark results indicate the MVME197 achieves over 
70 SPECmark8989 at 50 MHz. SPECmark89 reflects floating point and 
integer performance of the processor.

"The 88110-based MVME197 offers system level performance of more 
than three times over previous Motorola SBCs," said Don Anselmo, 
vice president and director of technical computing systems 
marketing and engineering.  "Our customers now have a choice 
between two RISC-based SBCs--the 88110 MVME197 and the 
award-winning MC88100 MVME187. The 197 provides customers with a 
superior performance advantage in demanding applications such as 
multimedia, imaging, and real-time complex I/O along with UNIX 
requiring multivendor configurations. The 187 also provides 
RISC-based performance levels, but at a lower cost. We also 
designed the board with leading edge peripheral technology and a 
unique memory array design resulting in a highly integrated 
solution."

The MVME197 is MCG's first Symmetric Superscalar SBC and supports 
SCSI-2, serial I/O and networking all in a single VMEbus slot. "The 
module's unsurpassed performance is a result of a unique 
combination of the 88110 MPU with six Motorola- developed ASICs 
(application specific integrated circuits)," said Jerry Gipper, 
director of VME components marketing. 


State-of-the-Art 88110 MPU

The 88110 Symmetric Superscalar RISC microprocessor architecture 
combines high performance and implementation flexibility, while 
maintaining software compatibility with the MC88100 MPU. The 
MVME197 will be supported by Motorola's UNIXR SYSTEM V/88TM Release 
4.0, an enhanced implementation of UNIX System Laboratories' UNIX 
System V, VMEexec and leading real-time, third-party software 
products.


ASICs

The use of Motorola-designed ASICs achieves the level of 
integration required to develop a single board solution with 
excellent performance. Motorola accomplished this by dedicating 
over 30 man-years of research to the development of the six 
advanced, third-generation ASICs used on the MVME197 board. "The 
custom ASICs were designed specifically for Motorola products, 
resulting in the greatest optimization and functionality possible," 
Gipper said.


Leading Edge Peripheral Technology

According to Gipper, intelligent peripheral controllers are used in 
order to insure the local bus operates at optimum performance 
levels.   A BusSwitch converts the local peripheral's 32-bit data 
bus to the 88110's 64-bit system bus. "With the BusSwitch, existing 
MC68040 peripherals that have been customized and optimized for the 
MC68040 can also work with the 88110," Gipper said. "This prevents 
the need for special peripherals for the 88110, provides easy 
transition to the 88110 architecture and maximizes performance."


Unique Memory Array Design Enhances Performance

"The greatest challenge in designing a SBC with the performance 
capability of the 88110 is providing data to the processor fast 
enough for it to operate at maximum performance levels," Gipper 
said. The MVME197 is designed with a unique memory architecture 
that supports burst data transfers and provides error checking and 
correction (ECC), enabling the board to operate at peak performance 
during all operations. Sustained burst transfers as fast as 3/1/1/1 
cycles are possible between the 88110 and main memory, allowing 
performance levels of over 70 simulated SPECmark89 at 50 MHz.


Key features of the MVME197 include:

o	High Density ASICs: Six ASICs provide increased functionality, 
lower power consumption and higher reliability through reduced 
component count.
o	SCSI Interface: The on-board, programmable 8-bit SCSI interface 
with 32-bit Local Bus DMA maximizes I/O throughput and supports 
SCSI synchronous transfers up to 10 megabytes per second (MB/s).	

o	Ethernet Interface: The 10 MB/s Ethernet controller has a 
built-in DMA controller and a 32-bit local bus interface to 
optimize the use of the system bus.

o	Parallel Interface: The 8-bit bidirectional parallel interface 
may be used as a printer port or a parallel data collection/control 
port for real-time applications.

o	Serial Port: Four on-board serial channels are available, which 
support asynchronous and synchronous transfers.

o	UNIX System V Support: Supported by UNIX SYSTEM V/88, Release 
4.0, Motorola's implementation of UNIX System Laboratories UNIX 
System V, which complies with 88openTM Binary Compatibility 
Standard (BCS) and Object Compatibility Standard (OSC).

o	VME D64 Protocol: An optimized VME D64 compatible interface 
capable of data transfers exceeding 40 megabytes per second (MB/s).

o	VMEexec, Motorola's full line of development tools to develop 
real-time applications entirely within a standard UNIX environment.
