{\bf
Reconfigurable systolic architecture
}


\vspace {.1in}
\noindent
{\bf Architecture:}
Five basic components:
(1) system control unit (DEC Micro VAX II),
(2) matrix processing unit (Systolic processor) with 2 to 8 Mbytes of local memory,
(3) mass storage system, an I/O interface system for access to high-speed data storage peripherals,
(4) system memory (64 to 2048 Mbytes SECDED), and
(5) Saxpy Interconnect - a control and data bus (320 Mbytes/sec transfer rate).

\noindent
{\bf Configuration:}
Possible configurations for the Matrix Processor are shown in the table
below.

{\bf Software:}
VAX/VMS Operating system.
MATRIX 1 Fortran is Fortran-77 with some 8x extensions.
There are several Saxpy-supplied libraries.
The Standard Subroutine Library provides basic system and data
manipulation functions in addition to some simple BLAS level
calculation subroutines; there are also some simple synchronization
subroutines.
The Engineering and Scientific Subroutine Library includes
high-level matrix arithmetic subroutines (utilizing block algorithms
for efficiency on the matrix processing unit), fast Fourier transform
routines, convolution and correlation subroutines, and further utility
subroutines.
The Signal-Processing Subroutine Library includes spectral analysis,
digital filtering, beam forming, and direction-finding subroutines.

\vspace {.1in}
\noindent
{\bf Languages:}
HiMAT language 
in C-based and Fortran 77-based version.

\vspace{.1in}
\noindent
{\bf Applications:}
Major application areas include signal and seismic processing,
image processing, and numerical analysis.

\vspace {.1in}
\noindent
{\bf Status:}
Machines are priced from \$695,000 to \$1.9M. A fully
configured system including a MATRIX 1/1000 would cost around \$3M.

\vspace {.1in}
\noindent
Beta units installed in April 1987.
Customers include Martin Marietta Baltimore Aerospace.
First production delivery made in March 1988.
