Fields that are now often introduced with coordinate-free treatments include vector calculus, tensors, differential geometry, and computer graphics. In physics, the existence of coordinate-free treatments of physical theories is a corollary of the principle of general covariance. See also. General covariance; Foundations of geometry
List of file signatures. This is a list of file signatures, data used to identify or verify the content of a file. Such signatures are also known as magic numbers or Magic Bytes. Many file formats are not intended to be read as text. If such a file is accidentally viewed as a text file, its contents will be unintelligible.
A bit array (also known as bitmask, [1] bit map, bit set, bit string, or bit vector) is an array data structure that compactly stores bits. It can be used to implement a simple set data structure. A bit array is effective at exploiting bit-level parallelism in hardware to perform operations quickly. A typical bit array stores kw bits, where w ...
Free Download Manager is a download manager for Windows, macOS, Linux and Android. [4] [5] Free Download Manager is proprietary software, but was free and open-source software between versions 2.5 [6] and 3.9.7. Starting with version 3.0.852 (15 April 2010), the source code was made available in the project's Subversion repository instead of ...
Bit field. A bit field is a data structure that consists of one or more adjacent bits which have been allocated for specific purposes, so that any single bit or group of bits within the structure can be set or inspected. [1] [2] A bit field is most commonly used to represent integral types of known, fixed bit-width, such as single-bit Booleans .
The AMD Radeon R9 290X (Sapphire OEM version pictured here) uses a 512 bit memory bus. The Intel Xeon Phi has a vector processing unit with 512-bit vector registers, each one holding sixteen 32-bit elements or eight 64-bit elements, and one instruction can operate on all these values in parallel. However, the Xeon Phi's vector processing unit ...
AltiVec prior to Power ISA 2.06 with VMX lacks 64-bit integer support. Developers who wish to operate on 64-bit data will develop routines from 32-bit components. For example, below are examples of 64-bit add and subtract in C using a vector with four 32-bit words on a big-endian machine. The permutes move the carry and borrow bits from columns ...
DreamWorks Animation said it will release its MoonRay ray-tracing renderer as open-source software later this year. As The Hollywood Reporter notes, DreamWorks will offer up its Arras cloud ...
