   THE INTEL MATH COPROCESSOR AND YOUR APPLICATIONS
   

       The Intel Math CoProcessor can speed up all kinds of business
       application software -- probably a program you're using now. The
       examples below give you a good idea of how the Intel Math CoProcessor
       accelerates a wide variety of application software.


   GRAPHICS AND DESKTOP PUBLISHING
   

       There are two types of graphics software: bit-mapped and vector-
       oriented.  Bit-mapped graphics use patterns of dots to make up lines,
       letters, boxes, and other shapes and does not take advantage of Intel
       Math CoProcessors.  Z-SOFT's PC Paintbrush is an example of a bit-
       mapped graphics package.

       Vector-oriented graphics, however, uses formulas to represent what the
       user draws or writes and can benefit from the Intel Math CoProcessor.
       For example, when the user draws a circle, the software actually calls
       up the formula for a circle. When the user saves the circle to disk,
       the formula gets stored.  And when the user changes the size or
       location of the circle, the software simply changes the parameters of
       its formula and recalculates.  The Intel Math CoProcessor makes these
       recalculations considerably faster, speeding up changes and other
       redraws.

       The benchmarks tests described here demonstrate significant speed
       improvement for specific business graphics applications.

   CHARTS & DIAGRAMS

       Picture Perfect and Diagraph/2000 are menu-driven business graphics
       programs from Computer Support Corporation.  Picture Perfect is
       designed to turn data into presentation-quality charts and graphs.
       Diagraph/2000 creates charts, diagrams, maps, symbols, forms, and much
       more.

       Both programs have been optimized for speed with the Intel Math
       CoProcessor.  They are vector-oriented and use floating point data and
       operations.  The math coprocessor helps most on diagrams with bold
       lines, shading, and shadowing.  The benchmarks show a time savings of
       65 to 80 percent for previewing a chart, and 63 to 75 percent for
       previewing text when a 287-10 Intel Math CoProcessor was added to a 286
       PC.

   FONT GENERATION

       Font generation is an excellent example of using math behind the
       scenes.  Users define the typefaces they want with a font package such
       as Bitstream's Fontware or SoftCraft, Inc.'s Spinfont or WYSIfonts!
       The software applies a formula to produce the size and typeface
       requested.  The Bitstream Fontware benchmarks show, on average, a 75
       percent time savings with an Intel Math CoProcessor.

   POSTSCRIPT EMULATION

       Freedom of Press from Custom Applications, Inc., allows you to print
       PostScript files on several non-postscript laser and 24-pin dot matrix
       printers.  The program uses the computer's memory to interpret the
       PostScript code and makes a customized bit map for your printer.  The
       customized bit map is generated using formulas, Intel Math CoProcessors
       speed up these formulas considerably.

       Benchmarks show that the 287 math coprocessor yielded a 44 percent time
       savings for an Epson LQ-850, and a 57 percent time savings for a
       Hewlett-Packard LaserJet Series II.

   COMPUTER-AIDED DESIGN

       Computer-aided design (CAD) is a classic graphics application for Intel
       Math CoProcessors.  Many CAD drawings are created by specifying
       coefficients for formulas.  Math coprocessors are used to generate and
       change drawings and are essential for image rotations and 3D diagrams.

       Many CAD packages today would be so slow without a math coprocessor
       that they require one.  Benchmarks were done with an older version
       (2.5) of Autodesk's AutoCAD to show the dramatic performance increases
       with Intel Math CoProcessors (newer releases of AutoCAD will not run
       without an Intel Math CoProcessor).  They show a 50 percent time
       savings for hidden line removal and a 77 percent time savings for
       drawing regeneration.


   SPREADSHEETS AND STATISTICS
   

       Intel Math CoProcessors speed up many common spreadsheet functions,
       though some operations are not accelerated at all. Since basic integer
       arithmetic (addition, subtraction, multiplication, division of whole
       numbers) is performed easily by the main CPU, the math coprocessor will
       not accelerate those functions.  However, floating point operations are
       laborious for the CPU and run considerably faster with an Intel Math
       CoProcessor.

       Floating point math includes basic arithmetic of numbers with decimals,
       trigonometric and exponential functions, and any operations that build
       on trigonometry or exponentiation. Many common financial and
       statistical functions are based on exponents and work much faster with
       an Intel Math CoProcessor.

       Consider the net present value formula, the function for the periodic
       interest rate, and the formula for standard deviation.  Because these
       functions contain exponents, they take advantage of the Intel Math
       CoProcessor's specialties. The Intel Math CoProcessor can speed up
       recalculation time for these and many other common financial and
       statistical operations.

   SPREADSHEETS

       The Lotus 1-2-3 Release 2.01 benchmarks show a sample of different
       functions.  Each function was tested for math coprocessor sensitivity
       by filling all of the cells in a large spreadsheet (200K to 400K) with
       that formula.  While this does not represent a realistic spreadsheet,
       it does give a precise indication of the Intel Math CoProcessor's
       effect on each function.

       The results show a range of time savings from 16 percent for
       multiplication and division to 80 percent for periodic interest rate
       (@rate).  This could add up to a savings of several hours a week for
       many spreadsheet users.

   STATISTICS

       Statistical analysis programs take advantage of Intel Math CoProcessors
       primarily when working with several data sets and doing floating point
       math.  The many statistical formulas which are based on exponents run
       much faster with an Intel Math CoProcessor installed.

       The benchmarks show statistical operations with STSC, Inc.'s
       STATGRAPHICS, a fully integrated statistical graphics system for PCs.
       The time savings with the Intel Math CoProcessor range from 8 percent
       for forecasting to 50 percent for correlation analysis.


   DATABASES
   

       Most database applications, including Ashton-Tate's dBASE IV, Fox
       Software's FoxBASE +, Borland's Paradox, and Nantucket's Clipper, make
       use of Intel's Math CoProcessors for math calculations included in the

       database program.  The dBASE IV benchmarks show a 65 percent savings
       for doing square root and logarithmic calculations.  This translates
       into similar time savings for any function that uses exponents or
       logarithms (net present value, standard deviation, variance, square
       root).
