3.9 Intel® Advanced Vector Extensions (Intel® AVX)
Intel® Advanced Vector Extensions (Intel® AVX) is a 256-bit vector SIMD extension of
Intel Architecture that continues with the 3rd Generation Intel® Core™ Processor
Family. Intel AVX accelerates the trend of parallel computation in general purpose
applications like image, video, and audio processing, engineering applications such as
3D modeling and analysis, scientific simulation, and financial analysts.
Intel AVX is a comprehensive ISA extension of the Intel 64 Architecture. The main
elements of Intel AVX are:
• Support for wider vector data (up to 256-bit) for floating-point computation.
• Efficient instruction encoding scheme that supports 3 operand syntax and
headroom for future extensions.
• Flexibility in programming environment, ranging from branch handling to relaxed
memory alignment requirements.
• New data manipulation and arithmetic compute primitives, including broadcast,
permute, fused-multiply-add, and so forth.
• Floating point bit depth conversion (Float 16)
• A group of 4 instructions that accelerate data conversion between 16-bit
floating point format to 32-bit and vice versa.
• This benefits image processing and graphical applications allowing
compression of data so less memory and bandwidth is required.
The key advantages of Intel AVX are:
• Performance - Intel AVX can accelerate application performance via data
parallelism and scalable hardware infrastructure across existing and new
application domains:
— 256-bit vector data sets can be processed up to twice the throughput of 128-bit
data sets.
— Application performance can scale up with number of hardware threads and
number of cores.
— Application domain can scale out with advanced platform interconnect fabrics,
such as Intel QPI.
• Power Efficiency - Intel AVX is extremely power efficient. Incremental power is
insignificant when the instructions are unused or scarcely used. Combined with the
high performance that it can deliver, applications that lend themselves heavily to
using Intel AVX can be much more energy efficient and realize a higher
performance-per-watt.
