  1. HP48 Simulator forWindows CE Roman Barsky Alon Nozic Supervisor: Alexander Arlievsky

  2. Introduction • HP 48 is a powerful scientific calculator, which is widely used by engineers, students and scientists • The project goal is to build a working model of the calculator, the Simulator, for the Embedded devices

  3. Supported Features (1) • Basic arithmetic operations. • Trigonometric functions. • The full set of hyperbolic functions. • Logarithmic and power functions. • Various data types: • Double • Integer (limited usage) • Complex (limited set of operations) • String • Algebraic expression • Program

  4. Supported Features (2) • Advanced stack architecture. • Working with algebraic expressions. • Possibility to define and store objects of all the types. • Programming features: • Block structure • If structures • Loop structures

  5. Example The Simulator at work

  6. Working on the Project Paradigms and Techniques

  7. Project Planning • The whole project was divided into two parts: “analytic” and “GUI” • Each part, in turn, consists of sub-projects

  8. Calc Sub-project • The tokenizer (built using FLEX lexical analyzer) • Recursive descent parser • 2 look-up tables • Main stack implementation • Mathematical functions implementation

  9. CE_STD Sub-project Partially replaces the Standard Template Library, which lacks in Visual Studio for Windows CE • Deque • String • Streams • Map • more…

  10. Characters Sub-project • The symbols are converted from one-byte representation to wide char and vice-versa. • Commonly used in the Simulator.

  11. Calculator Sub-project • Editor • Screen abstraction • Keyboard layer • Thread management • Initialization and shutting down • GUI

  12. The End Any questions?
