Micro Digital Announces GoFast for IAR EWARM

GoFast is a family of high-performance, reentrant, floating-point libraries designed for embedded applications.

Micro Digital Inc. is pleased to announce that the GoFast floating point library has been ported to the IAR EWARM http://www.mxrtos.com/ussw/gofast.htm tool suite for the ARM processor family.

GoFast is a family of high-performance, reentrant, floating-point libraries designed for embedded applications. They are ANSI C compatible and are designed to directly replace a C compiler's runtime floating-point support (library or coprocessor). GoFast boosts the performance of an application's math calculations or eliminates the need for hardware floating-point coprocessors, in order to reduce product manufacturing cost.

Low-level floating point functions in the EWARM library are coded in assembly, so GoFast offers no speed improvement for them. However, for higher-level functions such as square root, exponent, log, trigonometric, hyperbolic and others, the performance gain from GoFast is 2:1 to 4:1 and as high as 8:1. This can result in significant cost savings for GPS, surveying, guidance and other applications doing intensive trigonometic calculations by reducing hardware cost for a required performance level. Many other types of calculations involve square roots, exponents, logs and hyperbolic functions. Applications using these can also achieve significant cost savings using GoFast. Applications that are sluggish on particular hardware can show dramatic improvements in responsiveness, saving hardware redesign.

The accuracy of each GoFast Floating Point Library is within one (least significant) bit for arithmetic functions and two bits for transcendental functions, in most cases. The IEEE 754 Floating Point Format defines special representations for underflow, overflow, and invalid operation. The GoFast routines use these formats and adhere to the IEEE 754 error handling procedures in all applicable cases. Quality assurance and testing procedures have assured proper product operation. In addition, each delivery includes target specific test programs assuring confidence of product operation.
