| | RISC |
 | | Reduced (or regular) instruction set computer (or Computing) (RISC), is a computer CPU design philosophy that favors a smaller and simpler set of instructions that all take about the same amount of time to execute. | | | Many in the computer industry criticized that the performance benefits were unlikely to translate into real-world settings due to the decreased memory efficiency of multiple instructions, and that that was the reason no one was using them. | | | Cray designed it as a number-crunching CPU (with 74 op-codes, compared with a 8086 's 400) plus 12 simple computers to handle I/O (most of the operating system was in one of these). |

| | RISC Architectures |
| | (Berkeley UNIX was a DARPA-sponsored effort.) In the 1980s he spearheaded Sun's evangelism of the "open systems" model of computing, which allows different groups to contribute to a computer system by making the specifications of its components freely available. | | | RISC microprocessors have been the standard-bearers of performance, so Intel has embraced ideas from RISC and followed the quantitative approach. | | | RISC was also heralded a more quantitative approach to computer architecture, whereby careful experiments preceded the hardware design and sensible performance metrics were used to judge success. |

| | RISC Robotics |
| | RISC sensing employs simple but precise sensor elements that can be combined to form complete systems for localizing and recognizing arbitrary objects from a library. | | | The paradigm of RISC Robotics can be applied to many areas of manufacturing. | | | This results in algorithms for manipulation and sensing that are simple, very accurate and very fast. |

| | RISC architectures have been designed to exploit the programming environment in which most instructions are data movement or program control instructions. | | | RISC processors have simpler instruction sets than CISC processors (although this is a rather crude distinction between these families, as we shall soon see). | | | According to popular wisdom RISC architectures are streamlined versions of traditional complex instruction set computers. |

| | Great Microprocessors of the Past and Present |
| | RISC is more commonly used to refer to a design philosophy than a list of features (actually implementation techniques), especially since most of them have been applied to CISC designs (pipelines as far back as the Zilog Z8000, register windows in the Hitachi H16 and H32, and microcode eliminated in most modern designs). | | | The Berkeley project also produced an instruction cache with some innovative features, such as instruction line prefetch that identified jump instructions, frequently used instructions compacted in memory and expanded upon cache load, multiple cache chips support, and bits to map out defective cache lines. | | | Basically, RISC asks whether hardware (for complex instructions or memory-to-memory operations) is necessary, or whether it can be replaced by software (simpler instructions or load/store architecture). |

| | California Digital Computer (CALDIC) (1951) This easy-to-understand, low-cost computer was developed by Berkeley students like Doug Englebart and Al Hoagland, and led by Professor Paul Morton. | | | California Digital Computer (CALDIC) (1951) Designed for for the benefit of Berkeley's research, it was a low-cost machine designed for simplicity of description and operation. | | | Some of the 940 system's ideas are also embodied in Unix, whose designer Ken Thompson worked on the 940 while at Berkeley. |

| | Berkeley MPEG Tools |
| | The Berkeley decoder has been ported to seemingly every computer system, and it has been distributed to millions of users on the Internet. | | | The Berkeley Plateau Multimedia Research Group (now subsumed by the Berkeley Multimedia Research Center (BMRC)) developed the first widely-distributed software decoder for MPEG-1 video in November 1992. |

| | Great Microprocessors of the Past and Present |
| | Simplicity was the primary design goal, and in that sense it was one of the first "RISC" chips. | | | The Intel 8086 was based on the design of the 8080/8085 (source compatible with the 8080) with a similar register set, but was expanded to 16 bits. | | | In addition, parts that used to be separate (FPU, MMU) are now usually considered part of the CPU design. |

| | Rural Infrastructure and Services Commons -- Atanu Dey |
| | RISC follows the logical trend of moving away from vertically integrated institutions to one of horizontal segmentation and specialization. | | | Neither is it another model of internet kiosk or telecenter. | | | These services would require infrastructural inputs which can be commercially and sustainably supplied. |
