Intel 80286The Intel80286 (also marketed as the iAPX 286 and often called Intel 286) is a 16-bitmicroprocessor that was introduced on February 1, 1982. It was the first 8086-based CPU with separate, non-multiplexedaddress and data buses and also the first with memory management and wide protection abilities.
I386The Intel 386, originally released as the 80386 and later renamed i386, is the third-generation x86microprocessor developed by Intel. It is the first 32-bit processor in the line, and the first to implement the full IA-32 microarchitecture, marking a significant increase in capabilities while maintaining full compatibility with legacy code. Pre-production samples of the 386 were released to select developers in October 1985, while mass production commenced in June 1986.
Floating-point unitA floating-point unit (FPU), numeric processing unit (NPU), colloquially math coprocessor, is a part of a computer system specially designed to carry out operations on floating-point numbers. Typical operations are addition, subtraction, multiplication, division, and square root. Modern designs generally include a fused multiply-add instruction, which was found to be very common in real-world code.
IntelAmerican multinational technology companyIntel Corporation is an American multinational technology company headquartered in Santa Clara, California. It designs, manufactures, and sells computer components such as central processing units (CPUs) and related products for business and consumer markets.
DhrystoneDhrystone is a synthetic computing benchmark program developed in 1984 by intended to be representative of system (integer) programming. The Dhrystone grew to become representative of general processor (CPU) performance. The name "Dhrystone" is a pun on a different benchmark algorithm called Whetstone, which emphasizes floating point performance.
MicroprocessorA microprocessor is a computer processor for which the data processing logic and control is included on a single integrated circuit (IC), or a small number of ICs. The microprocessor contains the arithmetic, logic, and control circuitry required to perform the functions of a computer's central processing unit (CPU). The microprocessor is capable of interpreting and executing machine code and performing arithmetic operations.
Cache (computing)In computing, a cache ( ) is a hardware or software component that stores data so that future requests for that data can be served faster; the data stored in a cache might be the result of an earlier computation or a copy of data stored elsewhere. A cache hit occurs when the requested data can be found in a cache, while a cache miss occurs when it cannot.
Intel 8086The 8086 (also called iAPX 86) is a 16-bit microprocessor chip released by Intel on June 8, 1978 after development began in early 1976. It was followed by the Intel 8088 in 1979, which was a slightly modified chip with an external 8-bit data bus (allowing the use of cheaper and fewer supporting ICs). The 8086 gave rise to the x86 architecture, which eventually became Intel's most successful line of processors.
VAX Unit of PerformanceThe VAX Unit of Performance, or VUP for short, is an obsolete measurement of computer performance used by Digital Equipment Corporation (DEC). 1 VUP was equivalent to the performance of a VAX 11/780 completing a given task. One VUPS was roughly equivalent to 1 MIPS, and can be used interchangeably in most cases.X86x86 (also known as 80x86 or the 8086 family) is a family of complex instruction set computer (CISC) instruction set architectures initially developed by Intel, based on the 8086 microprocessor and its 8-bit-external-bus variant, the 8088. The 8086 was introduced in 1978 as a fully 16-bit extension of Intel's 8-bit 8080 microprocessor, with memory segmentation as a solution for addressing more memory than can be covered by a plain 16-bit address.Instruction pipeliningIn computer engineering, instruction pipelining is a technique for implementing instruction-level parallelism within a single processor. Pipelining attempts to keep every part of the processor busy with some instruction by dividing incoming instructions into a series of sequential steps (the eponymous "pipeline") performed by different processor units with different parts of instructions processed in parallel.Binary-code compatibilityBinary-code compatibility (binary compatible or object-code compatible) is a property of a computer system, meaning that it can run the same executable code, typically machine code for a general-purpose computercentral processing unit (CPU), that another computer system can run. Source-code compatibility, on the other hand, means that recompilation or interpretation is necessary before the program can be run on the compatible system.*As an Amazon Associate I earn from qualifying purchases.
