Benefits of technology

The patent describes a processing device that can perform a vector operation and store the result in a vector register. The device also has a swizzling network that can combine or change the order of data elements in the register to create a swizzle pattern simultaneously. The swizzled register can then store the swizzle pattern. The technical effect of this invention is that it allows for faster and more efficient processing of vector operations.

Problems solved by technology

However, when a swizzle instruction is interposed between other instructions, such as a load instruction, a vector instruction, and a store instruction the performance of a processor executing the instructions may be degraded.
As a result, processor performance can be significantly degraded.

Abstract

A swizzle pattern generator is provided to reduce an overhead due to execution of a swizzle instruction in vector processing. The swizzle pattern generator is configured to provide swizzle patterns with respect to data sets of at least one vector register or vector processing unit. The swizzle pattern generator may be reconfigurable to generate various swizzle patterns for different vector operations.

Description

CROSS-REFERENCE TO RELATED APPLICATION(S)[0001]This application claims the benefit under 35 U.S.C. §119(a) of Korean Patent Application No. 10-2011-0092604, filed on Sep. 14, 2011, in the Korean Intellectual Property Office, the entire disclosure of which is incorporated herein by reference for all purposes.BACKGROUND[0002]1. Field[0003]The following description relates to processing devices and swizzle instructions for vector operations.[0004]2. Description of the Related Art[0005]In recent years, processing data loads have drastically increased in many different fields, such as, multimedia, communication, and graphic applications to name but a few. Such an increase in data processing loads has had a significant effect on the performance of any number of processing devices, such as high-performance server computers, general personal computers (PCs), and even mobile devices. Typically, a processing device is required to process as much data as possible within a limited amount of tim...
