It describes computers with multiple processing elements that perform the same operation on multiple data simultaneously. Thus, such machines exploit data level parallelism. History The first use of SIMD instructions was in vector supercomputers of the early 1970s such as the CDC Star-100 and the Texas Instruments ASC, which could operate on a vector of data with a single instruction. Vector processing was especially popularized by Cray in the 1970s and 1980s. Vector-processing architectures are now considered separate from SIMD machines, based on the fact that vector machines processed the vectors one word at a time through pipelined processors (though still based on a single instruction), whereas modern SIMD machines process all elements of the vector simultaneously.[1] The first era of modern SIMD machines was characterized by massively parallel processing-style supercomputers such as the Thinking Machines CM-1 and CM-2. These machines had many limited-functionality processors that would work in parallel.

  • (PSW). Seven Bits Remain Unused While the Rest Nine Are Used
    8086/8088MP INSTRUCTOR: ABDULMUTTALIB A. H. ALDOURI The Flags Register It is a 16-bit register, also called Program Status Word (PSW). Seven bits remain unused while the rest nine are used. Six are status flags and three are control flags. The control flags can be set/reset by the programmer. 1. DF (Direction Flag) : controls the direction of operation of string instructions. (DF=0 Ascending order DF=1 Descending order) 2. IF (Interrupt Flag): controls the interrupt operation in 8086µP. (IF=0 Disable interrupt IF=1 Enable interrupt) 3. TF (Trap Flag): controls the operation of the microprocessor. (TF=0 Normal operation TF=1 Single Step operation) The status flags are set/reset depending on the results of some arithmetic or logical operations during program execution. 1. CF (Carry Flag) is set (CF=1) if there is a carry out of the MSB position resulting from an addition operation or subtraction. 2. AF (Auxiliary Carry Flag) AF is set if there is a carry out of bit 3 resulting from an addition operation. 3. SF (Sign Flag) set to 1 when result is negative. When result is positive it is set to 0. 4. ZF (Zero Flag) is set (ZF=1) when result of an arithmetic or logical operation is zero. For non-zero result this flag is reset (ZF=0). 5. PF (Parity Flag) this flag is set to 1 when there is even number of one bits in result, and to 0 when there is odd number of one bits. 6. OF (Overflow Flag) set to 1 when there is a signed overflow.

  • The 8086 Microprocessor
    11 The 8086 Microprocessor 1. Draw the pin diagram of 8086. Ans. There would be two pin diagrams—one for MIN mode and the other for MAX mode of 8086, shown in Figs. 11.1 and 11.2 respectively. The pins that differ with each other in the two modes are from pin-24 to pin-31 (total 8 pins).

What is the technology used in 8086 µµµP? Ans. It is manufactured using high performance metal-oxide semiconductor (HMOS) technology. It has approximately 29,000 transistors and housed in a 40-pin DIP package. 3. Mention and explain the modes in which 8086 can operate. Ans. 8086 µP can operate in two modes—MIN mode and MAX mode. When MN/MX pin is high, it operates in MIN mode and when low, 8086 operates in MAX mode. 194 Understanding 8085/8086 Microprocessors and Peripheral ICs through Questions and Answers For a small system in which only one 8086 microprocessor is employed as a CPU, the system operates in MIN mode (Uniprocessor). While if more than one 8086 operate in a system then it is said to operate in MAX mode (Multiprocessor).

Kounavis Usage for Computing Intel Labs, Circuits and Systems Research the GCM Mode Intel Corporation The Intel® PCLMULQDQ instruction is a new instruction available beginning with the all new 2010 Intel® Core™ processor family based on the 32nm Intel® microarchitecture codename Westmere. The PCLMULQDQ instruction performs carry-less multiplication of two 64-bit operands. This paper provides information on the instruction, and its usage for computing the Galois Hash. It also provides code examples for the usage of PCLMULQDQ, together with the Intel® AES New Instructions for efficient implementation of AES in Galois Counter Mode (AES-GCM). This version of the paper also provides high performance code examples for AES-GCM, and discloses, for the first time, their measured performance numbers. 323640-002 Revision 2.02 April 2014 Intel® Carry-Less Multiplication Instruction and its Usage for Computing the GCM Mode Contents Introduction ..................................................................................................................... 4 Preliminaries .................................................................................................................... 4 PCLMULQDQ Instruction Definition .................................................................................... 7 The Galois Counter Mode (GCM) .....................................................................................
