  • 5. Data Types
    IEEE FOR THE FUNCTIONAL VERIFICATION LANGUAGE e Std 1647-2011 5. Data types The e language has a number of predefined data types, including the integer and Boolean scalar types common to most programming languages. In addition, new scalar data types (enumerated types) that are appropriate for programming, modeling hardware, and interfacing with hardware simulators can be created. The e language also provides a powerful mechanism for defining OO hierarchical data structures (structs) and ordered collections of elements of the same type (lists). The following subclauses provide a basic explanation of e data types. 5.1 e data types Most e expressions have an explicit data type, as follows: — Scalar types — Scalar subtypes — Enumerated scalar types — Casting of enumerated types in comparisons — Struct types — Struct subtypes — Referencing fields in when constructs — List types — The set type — The string type — The real type — The external_pointer type — The “untyped” pseudo type Certain expressions, such as HDL objects, have no explicit data type. See 5.2 for information on how these expressions are handled. 5.1.1 Scalar types Scalar types in e are one of the following: numeric, Boolean, or enumerated. Table 17 shows the predefined numeric and Boolean types. Both signed and unsigned integers can be of any size and, thus, of any range. See 5.1.2 for information on how to specify the size and range of a scalar field or variable explicitly. See also Clause 4. 5.1.2 Scalar subtypes A scalar subtype can be named and created by using a scalar modifier to specify the range or bit width of a scalar type.

  • Floating-Point Exception Handing
    ISO/IEC JTC1/SC22/WG5 N1372 Working draft of ISO/IEC TR 15580, second edition Information technology ± Programming languages ± Fortran ± Floating-point exception handing This page to be supplied by ISO. No changes from first edition, except for for mechanical things such as dates. i ISO/IEC TR 15580 : 1998(E) Draft second edition, 13th August 1999 ISO/IEC Foreword To be supplied by ISO. No changes from first edition, except for for mechanical things such as dates. ii ISO/IEC Draft second edition, 13th August 1999 ISO/IEC TR 15580: 1998(E) Introduction Exception handling is required for the development of robust and efficient numerical software. In particular, it is necessary in order to be able to write portable scientific libraries. In numerical Fortran programming, current practice is to employ whatever exception handling mechanisms are provided by the system/vendor. This clearly inhibits the production of fully portable numerical libraries and programs. It is particularly frustrating now that IEEE arithmetic (specified by IEEE 754-1985 Standard for binary floating-point arithmetic, also published as IEC 559:1989, Binary floating-point arithmetic for microprocessor systems) is so widely used, since built into it are the five conditions: overflow, invalid, divide-by-zero, underflow, and inexact. Our aim is to provide support for these conditions. We have taken the opportunity to provide support for other aspects of the IEEE standard through a set of elemental functions that are applicable only to IEEE data types. This proposal involves three standard modules: IEEE_EXCEPTIONS contains a derived type, some named constants of this type, and some simple procedures.

  • Adaptivfloat: a Floating-Point Based Data Type for Resilient Deep Learning Inference
    ADAPTIVFLOAT:AFLOATING-POINT BASED DATA TYPE FOR RESILIENT DEEP LEARNING INFERENCE Thierry Tambe 1 En-Yu Yang 1 Zishen Wan 1 Yuntian Deng 1 Vijay Janapa Reddi 1 Alexander Rush 2 David Brooks 1 Gu-Yeon Wei 1 ABSTRACT Conventional hardware-friendly quantization methods, such as fixed-point or integer, tend to perform poorly at very low word sizes as their shrinking dynamic ranges cannot adequately capture the wide data distributions commonly seen in sequence transduction models. We present AdaptivFloat, a floating-point inspired number representation format for deep learning that dynamically maximizes and optimally clips its available dynamic range, at a layer granularity, in order to create faithful encoding of neural network parameters. AdaptivFloat consistently produces higher inference accuracies compared to block floating-point, uniform, IEEE-like float or posit encodings at very low precision (≤ 8-bit) across a diverse set of state-of-the-art neural network topologies. And notably, AdaptivFloat is seen surpassing baseline FP32 performance by up to +0.3 in BLEU score and -0.75 in word error rate at weight bit widths that are ≤ 8-bit. Experimental results on a deep neural network (DNN) hardware accelerator, exploiting AdaptivFloat logic in its computational datapath, demonstrate per-operation energy and area that is 0.9× and 1.14×, respectively, that of equivalent bit width integer-based accelerator variants.

  • PART III Basic Data Types
    PART III Basic Data Types 186 Chapter 7 Using Numeric Types Two kinds of number representations, integer and floating point, are supported by C. The various integer types in C provide exact representations of the mathematical concept of “integer” but can represent values in only a limited range. The floating-point types in C are used to represent the mathematical type “real.” They can represent real numbers over a very large range of magnitudes, but each number generally is an approximation, using a limited number of decimal places of precision. In this chapter, we define and explain the integer and floating-point data types built into C and show how to write their literal forms and I/O formats. We discuss the range of values that can be stored in each type, how to perform reliable arithmetic computations with these values, what happens when a number is converted (or cast) from one type to another, and how to choose the proper data type for a problem. We would like to think of numbers as integer values, not as patterns of bits in memory. This is possible most of the time when working with C because the language lets us name the numbers and compute with them symbolically. Details such as the length (in bytes) of the number and the arrangement of bits in those bytes can be ignored most of the time. However, inside the computer, the numbers are just bit patterns. This becomes evident when conditions such as integer overflow occur and a “correct” formula produces a wrong and meaningless answer.
