GoFast® is a family of high-performance floating-point libraries designed for embedded applications. The libraries 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 and eliminates the need for a hardware floating-point coprocessor, in order to reduce product manufacturing cost. GoFast® libraries are reentrant.
• Designed for real-time embedded systems
The GoFast IEEE 754 Floating Point Libraries are composed of single precision (32-bit format) and double precision (64-bit format) floating point routines and are delivered with full source code. Each library has been optimized for speed and footprint. Users are provided with comprehensive set of floating point operations including add, subtract, multiply, divide, square root, sine, cosine, tangent, arctangent, exponentiation, log, natural log, and ASCII and integer conversion routines to and from the floating point format. Since source code is delivered, a GoFast library can be customized to fit specific user application requirements.
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 library 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.
