Examples of this are the x86 calling conventions. Adhering to an ABI (which may or may not be officially standardized) is usually the job of a compiler , operating system, or library author. However, an application programmer may have to deal with an ABI directly when writing a program in a mix of programming languages, or even compiling a ...
These functions are typically called from a higher-level memory management library function such as malloc. In the original Unix system, brk and sbrk were the only ways in which applications could acquire additional heap space; later versions allowed this to also be done using the mmap call.
MIPS (Microprocessor without Interlocked Pipelined Stages) [1] is a family of reduced instruction set computer (RISC) instruction set architectures (ISA) [2]: A-1 [3]: 19 developed by MIPS Computer Systems, now MIPS Technologies, based in the United States.
The Ingenic JZ4725 is an example for a MIPS-based SoC. Through the 1990s, the MIPS architecture was widely adopted by the embedded market, including for use in computer networking , telecommunications , video arcade games , video game consoles , computer printers , digital set-top boxes , digital televisions , DSL and cable modems , and ...
A high-level overview of the Linux kernel's system call interface, which handles communication between its various components and the userspace. In computing, a system call (commonly abbreviated to syscall) is the programmatic way in which a computer program requests a service from the operating system [a] on which it is executed.
Perform an SMX function. The leaf function to perform is given in EAX. [t] Depending on leaf function, the instruction may take additional arguments in RBX, ECX and EDX. Usually 0 [u] Conroe/Merom, WuDaoKou, [107] Tremont: RDTSCP Read Time Stamp Counter and Processor ID. RDTSCP: 0F 01 F9: Read Time Stamp Counter and processor core ID. [v]
Some languages allow the calling convention for a function to be explicitly specified with that function; other languages will have some calling convention but it will be hidden from the users of that language, and therefore will not typically be a consideration for the programmer.
Examples of distributed memory (multiple computers) include MPP (massively parallel processors), COW (clusters of workstations) and NUMA (non-uniform memory access). The former is complex and expensive: Many super-computers coupled by broad-band networks. Examples include hypercube and mesh interconnections.
