Steele and JP Bonn Exogi LLC Las Vegas, Nevada, USA [email protected] Abstract—Simulation of large computational systems-on-a-chip runtime, rather than requiring mastery of a simulator-specific (SoCs) is increasing challenging as the number and complexity of domain-specific language (DSL) describing the binary-code components is scaled up. With the ubiquity of programmable translation task. components in computational SoCs, fast functional instruction- set simulation (ISS) is increasingly important. Much ISS has been done with straightforward functional models of a non-pipelined II.

  • Python Scope 3
    Class XII Computer Science : Python (Code: 083) Chapter: Functions Chapter : Functions Topics Covered: 1. Functions: scope Learning Outcomes: In this tutorial, we’ll learn: 1. What scopes are and how they work in Python 2. Why it’s important to know about Python scope 3. What is the LEGB rule 4. Using Python global statement and nonlocal statement Youtube Video Tutorial: 1. https://www.youtube.com/watch?v=07w3KkQqgi0 2. https://www.youtube.com/watch?v=R5uLNhRaGD0 3. https://www.youtube.com/watch?v=NdlWHlEgTn8 Python Scope Scope of a name (variables, functions etc) is the area of code where the name is created and can be used or accessed. A variable is only available from inside the region it is created. This is called scope. The scope of a name or variable depends on the place in our code where we create that variable. The Python scope concept is generally presented using a rule known as the LEGB rule. LEGB stand for Local, Enclosing, Global, and Built-in scopes. These are the names of Python scopes and also the sequence of steps that Python follows when accessing names in a program. Therefore in python there are 4 scopes 1. Local scope 2. Enclosing scope 3. Global scope 4. Built in scope 1 By Rajesh Singh ([email protected]) Class XII Computer Science : Python (Code: 083) Chapter: Functions Local Scope A variable created inside a function belongs to the local scope of that function, and can only be used inside that function. Example A variable created inside a function is available inside that function only: def myfunc(): x= 300 print(x) myfunc() print(x) # error, because x is created inside myfunc(), so it is available inside that function only Enclosing Scope (Function Inside a Function) A variable is available inside that function only in which it is created.

  • 210 CHAPTER 7. NAMES and BINDING Chapter 8
    210 CHAPTER 7. NAMES AND BINDING Chapter 8 Expressions and Evaluation Overview This chapter introduces the concept of the programming environment and the role of expressions in a program. Programs are executed in an environment which is provided by the operating system or the translator. An editor, linker, file system, and compiler form the environment in which the programmer can enter and run programs. Interac- tive language systems, such as APL, FORTH, Prolog, and Smalltalk among others, are embedded in subsystems which replace the operating system in forming the program- development environment. The top-level control structure for these subsystems is the Read-Evaluate-Write cycle. The order of computation within a program is controlled in one of three basic ways: nesting, sequencing, or signaling other processes through the shared environment or streams which are managed by the operating system. Within a program, an expression is a nest of function calls or operators that returns a value. Binary operators written between their arguments are used in infix syntax. Unary and binary operators written before a single argument or a pair of arguments are used in prefix syntax. In postfix syntax, operators (unary or binary) follow their arguments. Parse trees can be developed from expressions that include infix, prefix and postfix operators. Rules for precedence, associativity, and parenthesization determine which operands belong to which operators. The rules that define order of evaluation for elements of a function call are as follows: • Inside-out: Evaluate every argument before beginning to evaluate the function. 211 212 CHAPTER 8. EXPRESSIONS AND EVALUATION • Outside-in: Start evaluating the function body.

  • What Is Object-Oriented Perl?
    This is a series of extracts from Object Oriented Perl, a new book from Manning Publications that will be available in August 1999. For more information on this book, see http://www.manning.com/Conway/. What is object-oriented Perl? Object-oriented Perl is a small amount of additional syntax and semantics, added to the existing imperative features of the Perl programming language. Those extras allow regular Perl packages, variables, and subroutines to behave like classes, objects, and methods. It's also a small number of special variables, packages and modules, and a large number of new techniques, that together provide inheritance, data encapsulation, operator overloading, automated definition of commonly used methods, generic programming, multiply-dispatched polymorphism, and persistence. It's an idiosyncratic, no-nonsense, demystified approach to object-oriented programming, with a typically Perlish disregard for accepted rules and conventions. It draws inspiration (and sometimes syntax) from many different object-oriented predecessors, adapting their ideas to its own needs. It reuses and extends the functionality of existing Perl features, and in the process throws an entirely new slant on what they mean. In other words, it's everything that regular Perl is, only object-oriented. Using Perl makes object-oriented programming more enjoyable, and using object- oriented programming makes Perl more enjoyable too. Life is too short to endure the cultured bondage-and-discipline of Eiffel programming, or to wrestle the alligators that lurk in the muddy semantics of C++. Object-oriented Perl gives you all the power of those languages, with very few of their tribulations. And best of all, like regular Perl, it's fun! Before we look at object orientation in Perl, let’s talk about what object orientation is in general..

  • Lecture #24: Achieving Runtime Effects—Functions
    Lecture #24: Achieving Runtime Effects—Functions • Language design and runtime design interact. Semantics of func- tions make good example. • Levels of function features: 1. Plain: no recursion, no nesting, fixed-sized data with size known by compiler. 2. Add recursion. 3. Add variable-sized unboxed data. 4. Allow nesting of functions, up-level addressing. 5. Allow function values w/ properly nested accesses only. 6. Allow general closures. 7. Allow continuations. • Tension between these effects and structure of machines: – Machine languages typically only make it easy to access things at addresses like R + C, where R is an address in a register and C is a relatively small integer constant. – Therefore, fixed offsets good, data-dependent offsets bad. Last modified: Mon Mar 31 10:58:48 2008 CS164: Lecture #24 1 1: No recursion, no nesting, fixed-sized data • Total amount of data is bounded, and there is only one instantiation of a function at a time. • So all variables, return addresses, and return values can go in fixed locations. • No stack needed at all. • Characterized FORTRAN programs in the early days. • In fact, can dispense with call instructions altogether: expand func- tion calls in-line. E.g., def f (x): x *= 42 x_1 = 3 y=9+x; =⇒ =⇒ x_1 *= 42 g (x, y) becomes y_1 = 9 + x_1 g (x_1, y_1) f (3) • However, program may get bigger than you want. Typically, one in- lines only small, frequently executed functions.

  • Semantic Analysis of Ladder Logic
    Semantic Analysis of Ladder Logic A Thesis Presented in Partial Fulfillment of the Requirements for the Degree Master of Science in the Graduate School of The Ohio State University By Soumyashree Gad, M.S. Graduate Program in Computer Science and Engineering The Ohio State University 2017 Master's Examination Committee: Dr. Srinivasan Parthasarathy, Advisor Dr. P. Sadayappan c Copyright by Soumyashree Gad 2017 Abstract Purpose: A careful examination of Ladder Logic program reveals it's hierarchical nature and components, which makes it interpret able. Perhaps, using data mining techniques to interpret the top level and sub-level components can be really useful. This seems like a classification problem. The application of machine learning algo- rithms on the features extracted from ladder logic can give insights of the whole ladder logic code. The components and their interactions are intuitive which certainly add to the probability of getting better results. The learning in the PLC programming can be alleviated by converting the existing PLC code to commonly used formats such as JSON, XML etc. The goal is to consume ladder logic sample, break it down into minor components, identify the components and interactions between them and later write them to JSON. As Ladder logic is the most commonly used programming language for PLCs we decided to start the experiment with Ladder logic program sam- ples. Feature engineering combined with machine learning techniques should provide accurate results for the Ladder Logic data. Methods: The data set contains 6623 records for top level classification with 1421 ALARM, 150 STEP SEQUENCE, 96 SOLENOID samples and 5304 UNCLASSIFIED and 84472 records for sub-level classification which contains sub-level components of the all the ALARM and STEP SEQUENCE samples from the top level data set.

  • Lexical Closures for C++
    Lexical Closures for C++ Thomas M. Breuel ∗ Abstract We describe an extension of the C++ programming language that allows the nesting of function definitions and provides lexical closures with dynamic lifetime. Our primary motivation for this extension is that it allows the programmer to define iterators for collection classes simply as member functions. Such iterators take function pointers or closures as arguments; providing lexical closures lets one express state (e.g. accumulators) naturally and easily. This technique is commonplace in programming languages like Scheme, T, or Smalltalk-80, and is probably the most concise and natural way to provide generic iteration constructs in object oriented programming languages. The ability to nest function definitions also encourages a modular programming style. We would like to extend the C++ language in this way without introducing new data types for closures and without affecting the efficiency of programs that do not use the feature. In order to achieve this, we propose that when a closure is created, a short segment of code is generated that loads the static chain pointer and jumps to the body of the function. A closure is a pointer to this short segment of code. This trick allows us to treat a closure the same way as a pointer to an ordinary C++ function that does not reference any non-local, non-global variables. We discuss issues of consistency with existing scoping rules, syntax, allocation strate- gies, portability, and efficiency. 1 What we would like to add... and why We would like to be able to nest function definitions in C++ programs.
