Vector Floating Point Coprocessor

Up to armv7 ar architecture included floating point architecture is a floating point coprocessor extension to the instruction set architectures. Using the coprocessor access register software can determine whether the vfp is arm11 mpcore processor technical. In this research we have implemented a high performance autonomous floating point vector coprocessor fpvc that works independently within an embedded processor system.

Arm neon technology is a simd single instruction multiple data architecture extension for the arm cortex a series processors.

Vector floating point coprocessor. We have presented a unified approach to vector and scalar computation using a single register file for both scalar operands and vector elements. By offloading processor intensive tasks from the main processor coprocessors can accelerate system performance. It contains the following sections. About this document on page xii feedback on page xv.

For historical reasons the floating point extension is also called the vfp extension. A coprocessor is a computer processor used to supplement the functions of the primary processor. Typical operations are addition subtraction multiplication division and square root. Operations performed by the coprocessor may be floating point arithmetic graphics signal processing string processing cryptography or io interfacing with peripheral devices.

Software can determine whether the vfp is present by the use of the coprocessor arm1176jzf s technical. The vfp is implemented as a dedicated functional block and is mapped as coprocessor numbers 10 and 11. Coprocessors allow a line of computers to be customized so that customers who do not need the extra performanc. Vector floating point vfp the vfp coprocessor supports floating point arithmetic operations and is a functional block within the arm1176jzf s processor.

It can accelerate multimedia and signal processing algorithms such as video encodedecode 2d3d graphics gaming audio. This preface introduces the vfp11 vector floating point coprocessor technical reference manual for the arm1136jf s processor. The vfp coprocessor is mapped as coprocessor numbers 10 and 11. A floating point unit fpu colloquially a math coprocessor is a part of a computer system specially designed to carry out operations on floating point numbers.

In this research we have implemented a high performance autonomous floating point vector co processor fpvc that works independently within an embedded processor system. Vector floating point vfp the optional vfp coprocessor within each mp11 cpu supports floating point arithmetic. We have presented a unified approach to vector and scalar computation using a single register file for both scalar operands and vector elements.
