  1. Systems Programming Course Gustavo Rodriguez-Rivera

  2. CS Common Core Courses • Problem Solving and Object Oriented Programming • Programming in C • Foundations of Computer Science • Data Structures and Algorithms • Computer Architecture • Systems Programming

  3. Objective • Consolidate the programming skills from the previous core courses. • The System Programming course concentrates on how programs run in user space and how the interact with the OS. • It does not cover OS internals. That will be covered in the Operating Systems Course.

  4. Objective (cont.) • It solidifies the programming skills by having the students write large programs (>1000 lines). • The students will use tools like IDEs, debuggers, profilers, and source control to help them write good and maintainable code. • The students will learn how to work on teams.

  5. Objective (cont.) • Use of Scripting Languages. • The students will learn to write multi-process and multi-threaded programs.

  6. Topics • Address space. Structure of a Program. Text, Data, BSS, Stack Segments. • Review of Pointers, double pointers, pointers to functions • Use of an IDE and debugger to program in C and C++. • Executable File Formats. ELF, COFF, a.out. • Development Cycle, Compiling, Assembling, Linking. Static Libraries • Loading a program, Runtime Linker, Shared Libraries.

  7. Topics (cont.) • Scripting Languages. sh, bash, basic UNIX commands. • File creation, read, write, close, file mode. • IO redirection, pipes • Fork, wait, waitpid, signals. • Directories, creating, directory list. • Project: Writing your own shell. • Source Control Systems (CVS, SVN) and distributed (GIT, Mercurial)

  8. Topics (cont.) • Programming with Threads, thread creation. • Race Conditions, Mutex locks. • Socket Programming. • Iterative and concurrent servers. • Project: Implementing your own web server with threads and process concurrency. • Memory allocation. Problems with memory allocation. Memory Leaks, Premature Frees, Memory Smashing, Double Frees. • Execution Profiling.

  9. Textbook • No official Textbook. • Class Notes • Selected Documents and Tutorials available in the Internet • Recommended Textbook. • Advanced Programming in the UNIX Environment, Addison-Wesley, 1992.

  10. Credits • Dr. Douglas Comer wrote the initial proposal for the Systems Programming Course. • The proposal was reviewed by Tim Korb, Gustavo Rodriguez-Rivera and the Systems Faculty.

  11. Hardware Lab in the Computer Architecture Course By Gustavo Rodriguez-Rivera

  12. Introduction • We want to teach the students that computer programs are everywhere and not only in Windows, Linux, and Macintosh computers. • The students also program in • Robots • Phones • Embedded Processors • The students get hands on experience with both hardware and software.

  13. The Hardware Kit • The students buy a kit from the department at cost. • The kit contains, breadboard, wires, gates, PIC18 processor, LED display, speaker, and everything they need to do projects with the PIC18 processor. • PIC 18 processor: • 8 bit architecture • 2K RAM, 64KB Flash Memory for Programs • USB communication • Digital Input/Outputs, Analog inputs • Timers, interrupts • Assembly and C programming with Microchip’s MPLAB IDE

  14. The Hardware Kit

  15. Programming the PIC18 • The students write the Assembly or C program in a PC running Windows and the the MPLAB IDE environment. • The program is assembled/compile and downloaded to the PIC18 using a programmer called PICKit2.

  16. The MPLAB IDE

  17. Projects • Implementing a 7-Segment display decoder using AND, OR, NOT gates. • Ambient light using an RGB Full Color LED, Pulse Wide Modulation (PWM), push buttons, and the segment display. • Configurable Alarm Clock with selectable ring tones and interrupts. • Interfacing the PC and a servo motor using the USB port.

  18. Thanks! • You are invited to see some of the student’s projects here in the room. • The URL of the course is http://www.cs.purdue.edu/homes/cs250
