    Microprogramming is a rapidly emerging technology for the implementation of the control section of modem digital processing systems. An assessment was made of this approach to control unit design three years ago in a series of papers derived from the Third Annual Workshop on Microprogramming and published as a special issue of this TRANSACTIONS. This technology has matured in the ensuing three yea... View full abstract»

    Several methods of evaluating user programs are analyzed with respect to space and time requirements. The concept of an "ideal" directly executed language is introduced and it is argued that the "ideal" directly executed language for a contemporary computing system will not be either its source language or the language accepted by its base machine.

    Current architecture for microprogrammable machines vary widely. In order to avoid the applicability of the testing technique to a particular machine example, hardware, microware and microprograms are represented in a general fashion. This representation will account for a composite of features common to a large variety of contemporary machines. Such a general description seems to be absolutely ne... View full abstract»

    Microprogrammed computers are categorized by main memory/control storage (CS) organization for use in analysis of methods of allowing dynamic user microprogramming. A system design is described in which user microroutines are executed directly from main memory, rather than from writable control storage (WCS). This design is analyzed and compared with the use of WCS for allowing dynamic user microp... View full abstract»

  • A High-Level Language for Horizontal Microprogramming

    Cited by:  Papers (26)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (2976 KB)

    A high-level language, SIMPL (Single Identity MicroProgramming), for horizontal microprogramming has been developed. This language allows the SIMPL compiler to easily detect concurrent microoperations and to optimize their intricate timing and concurrency for generating highly parallel and efficient object microprograms in horizontal formats. This unique feature accrues from the single assignment ... View full abstract»

    This paper describes an algorithm for the synthesis of applications-oriented microcode for a dynamically microprogrammable computer. The synthesis algorithm provides an iterative method for generating specialized architectures. Current attempts at generating specialized architectures can be considered as manual tuning due to human generation of specialized microcode. Heuristic instruction synthesi... View full abstract»

    This paper provides a summary of the design features of a microprogram controlled high speed signal processor referred to as an analyzer unit (AU). It provides an overview of the interrelationship between processing requirements, a language structure in which these requirements can be efficiently programmed, and an AU design that can efficiently execute the processing requirements. Particular emph... View full abstract»

    The concept of microprogramming has been changing with the development of hardware technology to facilitate dynamic microprogramming and the development of software technology to facilitate user microprogramming. An examination of the status of microprogramming systems leads to a discussion of the design and implementation characteristics for both the hardware and software aspects of microprogramm...

    The efficient utilization of a two-level directly executable memory system is investigated. After defining the time and space product resulting from static allocation of the most often referenced pages, from paging, and from an optimal algorithm when the amount of primary memory is constrained, we introduce a learning algorithm. Its basic feature is to monitor references in such a way that it prev... View full abstract»

    The problem of how to determine minimal sets of tests for single and multiple faults in irredundant combinational circuits is dealt with. It is shown that the "Equivalent Sum of Products" form of the given network contains all the information necessary to derive a min; mal test set. A simple procedure which generates a minimal test set Ts for single faults is described. Fault masking is then studi... View full abstract»

    Piecewise approximation is described as a way of feature extraction, data compaction, and noise filtering of boundaries of regions of pictures and waveforms. A new fast algorithm is proposed which allows for a variable number of segments. After an arbitrary initial choice, segments are split or merged in order to drive the error norm under a prespecified bound. Results of computer experiments with... View full abstract»

  • On the Modeling of Demand Paging Algorithms by Finite Automata

    Publication Year: 1974, Page(s):870 - 874

    Two finite automata are devised for modeling two classes of demand paging algorithms. The first one of one input and three outputs models the class of algorithms with a constant amount of allocated space. The second one of one input and six outputs models the class of algorithms with a variable amount of allocated space. Some evaluation techniques are developed following each model. The memory sta...

  • Distinguishing Sets for Optimal State Identification in Checking Experiments

    A new concept, called distinguishing set or D-set is presented. Its use yields a considerable reduction in the length of checking sequences. Arbitrarily chosen examples have indicated a reduction of 30-50 percent. It is shown that the sequences of a distinguishing set actually constitute the optimum, i.e., minimum length, for state identification through input-output observations only. View full abstract»
