Cache control instructions are specific to a certain cache line size, which in practice may vary between generations of processors in the same architectural family. Caches may also help coalescing reads and writes from less predictable access patterns (e.g., during texture mapping ), whilst scratchpad DMA requires reworking algorithms for more ...
To clear the cache: Go to the "Tools" menu (the three horizontal ellipsis on the upper right of the browser) and click on "History" (Shortcut: Ctrl+H). Click on "Clear browsing data…" (Shortcut: Ctrl+⇧ Shift+Del). Select the types of data you want to clear, and include "Cached images and files" option.
Cache invalidation is a process in a computer system whereby entries in a cache are replaced or removed.. It can be done explicitly, as part of a cache coherence protocol. In such a case, a processor changes a memory location and then invalidates the cached values of that memory location across the rest of the computer system.
Loop unrolling, also known as loop unwinding, is a loop transformation technique that attempts to optimize a program's execution speed at the expense of its binary size, which is an approach known as space–time tradeoff.
The vertex buffer object specification has been standardized by the OpenGL Architecture Review Board Archived 2011-11-24 at the Wayback Machine as of OpenGL Version 1.5 (in 2003). Similar functionality was available before the standardization of VBOs via the Nvidia -created extension "vertex array range" [ 1 ] or ATI 's "vertex array object ...
The computer graphics pipeline, also known as the rendering pipeline, or graphics pipeline, is a framework within computer graphics that outlines the necessary procedures for transforming a three-dimensional (3D) scene into a two-dimensional (2D) representation on a screen. [1]
Some architectures such as PowerPC attempt to avoid the need for cacheline locking or scratchpads through the use of cache control instructions.Marking an area of memory with "Data Cache Block: Zero" (allocating a line but setting its contents to zero instead of loading from main memory) and discarding it after use ('Data Cache Block: Invalidate', signaling that main memory didn't receive any ...
In C and C++, the volatile keyword was intended to allow C and C++ programs to directly access memory-mapped I/O. Memory-mapped I/O generally requires that the reads and writes specified in source code happen in the exact order specified with no omissions. Omissions or reorderings of reads and writes by the compiler would break the ...
