21X86-64 — is a superset of the x86 instruction set architecture. x86 64 processors can run existing 32 bit or 16 bit x86 programs at full speed, but also support new programs written with a 64 bit address space and other additional capabilities.The x86 64… …
22Thunk — The word thunk has at least three related meanings in computer science. A thunk may be: * a piece of code to perform a delayed computation (similar to a closure) * a feature of some virtual function table implementations (similar to a wrapper… …
23Compiler optimization — is the process of tuning the output of a compiler to minimize or maximize some attributes of an executable computer program. The most common requirement is to minimize the time taken to execute a program; a less common one is to minimize the… …
24Garbage collection (computer science) — This article is about garbage collection in memory management. For garbage collection in an SSD, see garbage collection (SSD). For other uses, see garbage collection. In computer science, garbage collection (GC) is a form of automatic memory… …
25Random access machine — In computer science, random access machine (RAM) is an abstract machine in the general class of register machines. The RAM is very similar to the counter machine but with the added capability of indirect addressing of its registers. Like the… …
26PCI configuration space — is the underlying way that the Conventional PCI, PCI X and PCI Express perform auto configuration of the cards inserted into their bus. Contents 1 Technical information 2 Standardized registers 3 Bus enumeration …
27Microcode — is a layer of hardware level instructions and/or data structures involved in the implementation of higher level machine code instructions in many computers and other processors; it resides in special high speed memory and translates machine… …
28Instruction set — An instruction set, or instruction set architecture (ISA), is the part of the computer architecture related to programming, including the native data types, instructions, registers, addressing modes, memory architecture, interrupt and exception… …
29Data segment — A data segment is a portion of virtual address space of a program, which contains the global variables and static variables that are initialized by the programmer. This portion has a fixed size for each program depending upon the quantity of… …
30Joel McCormack — is the designer of the NCR Corporation version of the p code machine which is a kind of Stack machine popular in the 1970s as the preferred way to implement new computing architectures and languages such as Pascal and BCPL. The NCR design shares… …
