    It is well known that a continuing trend in the development of digital computers has been towards improved cost efficiency, leading to expansion into new applications. In large measure this trend has resulted from continuing improvements in component technology. Remarkable advances in the miniaturization and integration of electronic components, particularly in the past ten years, have ushered in ... View full abstract»

    The benefits of Large-Scale Integration (LSI) implementations have applied quite naturally to processors with relatively low performances and simple architectures; e.g., the one-chip microprocessors used in personal computers contain several thousand logic gates. Mainframe processors, however, have so far been limited to using logic chips that contain several hundred logic gates. The best use of L... View full abstract»

    Signal processing is a data processing domain that contains a diversity of applications, including speech processing, image processing, radar, sonar, medical imaging, data communications, seismic processing, and many others. Despite the diversity of the applications, this processing domain has a very structured set of characteristics. These include real-time operation, dominance of arithmetic oper... View full abstract»

  • Rectangular Transforms for Digital Convolution on the Research Signal Processor

    Publication Year: 1982, Page(s):424 - 430
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (759 KB)

    The Rectangular Transform (RT) method for computing convolutions belongs to a family of Reduced Computational Complexity (RCC) algorithms. Convolution calculations by the RT method were programmed for the Research Signal Processor (RSP) and run on the RSP simulator, giving tabulations of numbers of RSP machine cycles. One of the original objectives was to see how well the original RSP architecture... View full abstract»

    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (1209 KB)

    The Real-Time Signal Processor (RSP) is a microprocessor optimized to provide fast, cost-efficient processing for signal processing applications. In order for the RSP to become fully useful, a complete set of software support tools needed to be developed. The hardware design and software development, which took place between 1978 and 1980, resulted in many architectural features which minimized ha... View full abstract»

    Cited by:  Patents (2)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (691 KB)

    The advent of LSI technology makes common microprogrammable controllers very cost-effective today. This paper focuses on the application of microcontrollers for disk and diskette control functions and describes a custom-designed FET chip which is being developed for use in these types of controllers. The architecture, the functional organization, and the physical design of this chip are presented,... View full abstract»

  • Physical Design of a Custom 16-Bit Microprocessor

    Publication Year: 1982, Page(s):446 - 453
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (1040 KB)

    The physical chip design aspects of a 16-bit, single-chip, custom-macro-designed microprocessor are described. This microprocessor represents the IBM System Products Division's highest-density VLSI FET processor design to date. The chip is a complex arrangement of over 6500 VLSI circuits utilizing a state-of-the-art polysilicon-gate HMOS-1 (high-performance MOS) technology. The physical design of ... View full abstract»

  • Design Considerations for a VLSI Microprocessor

    Publication Year: 1982, Page(s):454 - 463
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (1120 KB)

    The machine architecture and design considerations for an interrupt-driven bipolar VLSI Microprocessor are presented. The processor is designed to a complex architecture and includes an integrated channel and a flexible storage interface. Floating-point functions are optional. A 3-ns custom bipolar technology was developed for the microprocessor, resulting in a very high circuit density package. T... View full abstract»

  • Bipolar Chip Design for a VLSI Microprocessor

    Publication Year: 1982, Page(s):464 - 474
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (1278 KB)

    In this paper, a pseudo-custom approach to bipolar VLSI chip design is presented, and a hierarchical structure of logic macros assembled from building blocks is described. A strategy of placing the logic macros along with algorithmically designed PLA structures and ROS with a placement aid, and of wiring the placement with an automatic wiring program, is discussed. The paper also focuses on the im... View full abstract»

    With the ever-increasing density, development cost, and turn-around time of VLSI chips it becomes increasingly important to have a design verification methodology which enables first-pass chips to be fully functional. The strategy discussed in this paper exploits the best attributes of the two traditional methods of design verification (i.e., software simulation and hardware modeling). Software si...

    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (1172 KB)

    The level of complexity and the turn-around time associated with the development of custom bipolar VLSI chips have defined the need for a highly structured physical and electrical design validation approach which can guarantee fully functional first-pass chips, yet be flexible enough to allow logical and physical designers the latitude necessary to achieve specified cost and performance objectives...

    As VLSI technology evolves, miniaturization demands more sophisticated tools, instruments, and controls to manufacture the VLSI components. IBM's facility at East Fishkill, New York, has the responsibility for the development and manufacture of semiconductor products used in IBM data systems. This requires a sophisticated set of processes, inspections, and tests operating as a fully integrated sys... View full abstract»
