Info on the FPE for the Apple IIgs. _______________________________________ From A-link_______ FLOATING POINT PROCESSING FOR YOUR APPLE The Byte Works is proud to announce support for the Floating Point Engine (FPE) by Innovative Systems. This card can speed up floating-point intensive programs by a factor of 40 to 120! The floating point card card is based on the Motorola MC68881 floating point processor (the same processor used in the Mac II). Support for the card is already available in the form of a special- order version of ORCA/Pascal. Starting with version 1.3, support for the card will be standard in ORCA/Pascal. The card is shipped with macros that allow your current versions of ORCA/M and APW make use of the incredible speed-ups this card can produce on floating point calculations. The Savage benchmark, a standard test of floating point calculations, serves as an excellent example of what can be done with this card. This benchmark requires 72 seconds to do a series of floating point operations using Apple's SANE Floating Point package. With the FPE and ORCA/Pascal, the benchmark is done in under 1 second! The list price for Innovative Systems Floating Point Engine is $199.95. It can be purchased from Innovative Systems 7892 Covington Ave. Glen BurnieD 21061

I've heard some about it but I haven't heard anything about how well it works. I would really appreciate any info (and I'm sure a lot of other people would too.) Thanks in advance.. Collin Douglas

A friend brorrowed me his FPE. Nice. But Innovative Systems forgot something: A patch for the Integer Math tools to use the 68881 too. At least the integer and long integer multiplication and division could be speeded up. (Multiply and SDivide are used a lot in many toolsets...) Does anybody know if iS intends to release such a setup file? (If not -- writing one wouldn't be hard; I'll do it if I get my hands on that card again...)

Could someone refresh my memory on roughly how much the Innovative System's FPE speeds up a IIGS (already with a stock Transwarp)? I know the answer differs some depending on whether you are using, say, a compiler that compiles code for it directly or whether you are simply relying on the patches to the SANE tools. Pick a reasonable computation-intensive benchmark (e.g., fractals or something equivalent.) thanks; I know I saw something along these lines recently, but can't remember where. lee@TIS.COM
