The Khronos group uses blocks syntax to enqueue kernels from within kernels as of version 2.0 of OpenCL. [5] Like function definitions, blocks can take arguments, and declare their own variables internally. Unlike ordinary C function definitions, their value can capture state from their surrounding context.
Emulating self-modifying code, especially when it must be reentrant or read-only. [19] In the IBM System/360, the execute instruction can modify bits 8-15 of the target instruction, effectively turning an instruction with a fixed argument (e.g., a length field) into an instruction with a variable argument.
In computer file systems, a block allocation map is a data structure used to track disk blocks that are considered "in use". Blocks may also be referred to as allocation units or clusters. [1] CP/M used a block allocation map in its directory. Each directory entry could list 8 or 16 blocks (depending on disk format) that were allocated to a file.
ARM's Thumb instruction set (1994) dropped conditional execution to reduce the size of instructions so they could fit in 16 bits, but its successor, Thumb-2 (2003) overcame this problem by using a special instruction which has no effect other than to supply predicates for the following four instructions. The 64-bit instruction set introduced in ...
So the first byte held a map for blocks 0 to 7, the second byte held a map for blocks 8 to 15, and so on. Within a byte, the bitmap was ordered low-bit first. For example, the first byte would represent block 0 with the least significant bit and block 7 with the most significant bit.
The C and Java execution models are sequential, and they state that the timeline has activities that come before the call to "gain ownership of the lock", and activities that come after the call. Likewise there is a "give up ownership of the lock" operation. In C this would be pthread_mutex_unlock(&myMutex). In Java this would be lock.unlock().
Notable programming sources use terms like C-style, C-like, a dialect of C, having C-like syntax. The term curly bracket programming language denotes a language that shares C's block syntax. [1] [2] C-family languages have features like: Code block delimited by curly braces ({}), a.k.a. braces, a.k.a. curly brackets; Semicolon (;) statement ...
In computer programming, a block or code block or block of code is a lexical structure of source code which is grouped together. Blocks consist of one or more declarations and statements . A programming language that permits the creation of blocks, including blocks nested within other blocks, is called a block-structured programming language .
