A scalar processor is classified as a single instruction, single data ( SISD) processor in Flynn's taxonomy. The Intel 486 is an example of a scalar processor. It is to be contrasted with a vector processor where a single instruction operates simultaneously on multiple data items (and thus is referred to as a single instruction, multiple data ...
A stack register is a computer central processor register whose purpose is to keep track of a call stack. On an accumulator-based architecture machine, this may be a dedicated register. On a machine with multiple general-purpose registers, it may be a register that is reserved by convention, such as on the IBM System/360 through z/Architecture ...
x86 debug register. On the x86 architecture, a debug register is a register used by a processor for program debugging. There are six debug registers, named DR0 ... DR7, with DR4 and DR5 as obsolete synonyms for DR6 and DR7. The debug registers allow programmers to selectively enable various debug conditions associated with a set of four debug ...
5 de fev. de 2019 · Processor Register: A processor register is a local storage space on a processor that holds data that is being processed by CPU. Processor registers generally occupy the top-most position in the memory hierarchy, providing high-speed storage space and fast access to data. A register may include the address of the memory location instead of the ...
Instruction register. In computing, the instruction register ( IR) or current instruction register ( CIR) is the part of a CPU 's control unit that holds the instruction currently being executed or decoded. [1] In simple processors, each instruction to be executed is loaded into the instruction register, which holds it while it is decoded ...
Central processing unit. A Pentium CPU inside a computer. A central processing unit ( CPU) is an important part of every computer. [1] The CPU sends signals to control the other parts of the computer, almost like how a brain controls a body. [2] The CPU is an electronic machine that works on a list of computer things to do, called instructions.
Trusted Execution Technology. Intel Trusted Execution Technology ( Intel TXT, formerly known as LaGrande Technology) is a computer hardware technology of which the primary goals are: Attestation of the authenticity of a platform and its operating system. Assuring that an authentic operating system starts in a trusted environment, which can then ...
