Minimal Instruction Set Computer MISC is a Microprocessor processor architecture with a very small number of basic operations and corresponding opcode s. Such instruction set s are commonly stack based rather than register based to reduce the size of operand specifiers. Such a stack machine architecture is inherently simpler since all instructions operate on the top most stack entries. A result of this is a smaller instruction set, a smaller and faster instruction decode unit, and overall faster operation of individual instructions. The downside is that instructions tend to have more sequential dependencies, reducing instruction level parallelism . MISC architectures have much in common with the Forth programming language and the Java Virtual Machine . Probably the most commercially successful MISC was the INMOS transputer .

The ZISC acronym and initialism acronym alludes to the previously developed Reduced instruction set computer RISC Reduced Instruction Set Computer technology. ZISC is a technology based on ideas from artificial neural network s and massively hardwired parallel processing. This concept was invented by Guy Paillet. Fact date April 2008 It was inspired by his collaboration with Carlo Rubbia s team for parallel processing, and with Leon Cooper in the early 90s around the RCE Restricted Coulomb Energy , a neural network model published by Cooper et al. 1982 . RCE was inspired by Bruce Batchelor s Cardiff University UK book Practical Approach to Pattern Classification , especially the compound classifier .

Within the field of human computer interaction there has long been interest in developing adaptive automated instruction software to facilitate learning of application programs. This software would monitor a computer user s behavior while he or she uses the application program, and then provide optimized and personalized instruction to help the user become more skilled with the application. This form of instruction could be performed by a stand alone tutoring application, or it could be carried out by special routines built into the application program itself as with the Microsoft Office Assistant discussed below . Note that the history of adaptive learning approaches to education in general, some of which is summarized in the Wikipedia articles on spaced repetition and electronic learning , lies beyond the scope of this entry. Chronology of developments in the field A variety of different strategies for automated instruction in computer applications have been discussed and tried over a period of at least 25 years, although at present the technology does not appear to enjoy very wide application.

Instructions which, in out of order execution , are put aside into a shelving buffer or are waiting in an instruction queue are not thought of being inside of an instruction window. Instruction pipeline Pipelined instructions in different states of processing are not in the same instruction window. Both concepts might be visualized as being orthogonal to each other. In more complex situations each pipeline step could be viewed as having its own instruction window, or each slot in an instruction window having its own pipeline.

Unreferenced date January 2009 In computerscience , instruction selection is the stage of a compiler backend that transforms its tree based middle level intermediate representation IR into a low level IR very close to its final target language. In a typical compiler, it precedes both instruction scheduling and register allocation , so its output IR has an infinite set of pseudoregisters and may still be subject to peephole optimization otherwise, it closely resembles the target machine code , bytecode , or assembly language . It works by covering the intermediate representation with as few tiles as possible. A tile is a template that matches a portion of the IR tree and can be implemented with a single target instruction. Approach A basic approach in instruction selection is to use some templates for translation of each instruction in an intermediate representation. But na ve use of templates leads to inefficient code in general. Additional attention needs to be paid to avoid duplicated memory access by reordering and merging instructions and promote the usage of registers. For example, see the following sequence of intermediate instructions pre t1 a t2 b t3 t1 t2 a t3 b t1 pre A good tiling for the x86 architecture is a succinct set of instructions pre XCHG EAX, b ADD a, EAX pre Typically, instruction selection is implemented with a backwards dynamic programming algorithm which computes the optimal tiling for each point starting from the end of the program and based from there.

An instruction step is a method of executing a computer program one step at a time to determine how it is functioning. This might be to determine if the correct program flow is being followed in the program during the execution or to see if Variable programming variables are set to their correct values after a single step has completed. Hardware instruction step On earlier computers, a knob on the computer console may have enabled step by step execution mode to be selected and execution would then proceed by pressing a single step or single cycle button.

Compu prog stub ...Unreferenced stub auto yes date December 2009 A macro instruction is a line of computer program coding that results in one or more lines of program coding in the target programming language, sets variables for use by other statements, etc.. In the mid 1950s, when assembly language programming was commonly used to write programs for digital computers , the use of macro instructions was initiated for two main purposes to reduce the amount of program coding that had to be written by generating several assembly language statements from one macro instruction and to enforce program writing standards, e.g. specifying input output commands in standard ways. Macro instructions were effectively a middle step between assembly language programming and the high level programming languages that followed, such as FORTRAN and COBOL . Two of the earliest programming installations to develop macro languages for the IBM 705 computer were at Dow Chemical Corp. in Delaware and the Air Material Command, Ballistics Missile Logistics Office in California. A macro instruction written in the format of the target assembly language would be processed by a macro compiler, which was a pre processor to the assembler, to generate one or more assembly language instructions to be processed next by the assembler program that would translate the assembly language instructions into machine language instructions. While macro instructions can be defined by a programmer as a shorthand for any set of native assembler program instructions, typically macros are associated with macro libraries delivered with the operating ... of define constant instructions representing the parameters of the macro instruction such as a reference to a file and a data area for a READ instruction followed by either a branch and link instruction to call a routine, or a supervisor call instruction to call an operating system function directly ... more details

nofootnotes date January 2010 In computer architecture , instruction prefetch is a technique used in microprocessor s to speed up the execution of a program by reducing wait state s. Modern microprocessors are much faster than the Random access memory memory where the program is kept, meaning that the program s instructions cannot be read fast enough to keep the microprocessor busy. Adding a CPU cache cache can provide faster access to needed instructions. Prefetching occurs when a processor requests an instruction from Computer data storage Primary storage main memory before it is actually needed. Once the instruction comes back from memory, it is placed in a cache. When an instruction is actually needed, the instruction can be accessed much more quickly from the cache than if it had to make a request from memory. Since programs are generally executed sequentially, performance is likely to be best when instructions are prefetched in program order. Alternatively, the prefetch may be part of a complex branch prediction algorithm , where the processor tries to anticipate the result of a calculation and fetch the right instructions in advance. In the case of dedicated hardware like a Graphics Processing Unit the prefetch can take advantage of the spatial coherence usually found in the texture mapping process. In this case, the prefetched data are not instructions, but texture elements Texel graphics texels that are candidates to be mapped on a polygon . The first mainstream microprocessors to use some form of instruction prefetch were the Intel 8086 six bytes and the Motorola 68000 four bytes .
