Overview September 2008 | LINUX For YoU | www. openItis. com72 Even if C is losing its position as the mainstream programming language for general application development, embedded programming is still its stronghold. Students and programmers new to embedded programming, though proficient in general C programming, are often clueless about C programming for embedded systems. This article offers an introduction. very embedded system has software and hardware elements that are very closely dependent, and this affects how we program an embedded device. Based on this fact, we’ll look at the hardware characteristics of embedded devices, how the hardware affects the language chosen to write programs for it, how C is used differently for embedded programming and, finally, we’ll cover how GCC is used for embedded systems. Characteristics of embedded devices Programming for embedded systems is quite different from general programming (for PCs). The main difference is due to the underlying

88 AUGUST 2007 | LINUX FOR YOU | www. linuxforu. com C M Y K IIIII n most of the cases, writing fractal programs requires a good knowledge of mathematics. The Mandelbrot set is based on the theory and use of complex numbers. The Mandelbrot set is a collection of complex numbers, which have two parts: real and imaginary. Usually, a complex number is represented in the form, a + bi , where a is the real part and b is the imaginary part (the suffix i indicates that). A complex plane has real numbers in the xaxis and imaginary numbers in the y-axis. Given the complex numbers Z and C, the Mandelbrot set is formed by the formula: Z = Z ** 2 + C. Here ** stands for square. C is the number we test to see if the number is inside or outside the set. We start Z from zero and keep reassigning it as we change C, using this formula. Given a complex number a + bi, the formula for finding the square of a complex number is: a**2 – b**2 + 2abi. So, the real part is a**2 – b**2 and the i

September 2008 | LINUX For YoU | www. openItis. com106 S. G. GaneSh The Joy of Programming C /C++ allows only integer types for use in case statements. Why can’t we use floating point numbers? Because C designers thought that it is not a good idea: checking the exact equality in floating point is not portable [ref: C99 rationale]. How about string literals? It is allowed in many languages that evolved from C, such as C#, which is a useful feature. Since switch is for integral types, a compiler can translate it to efficient code, as we will now see. Which of the two is better: a switch statement or cascading if-else statements? Well, a switch expresses the programmer’s intentions more clearly than an if-else cascade. Also, you might be surprised to know that a switch is, in general, more efficient than an equivalent if-else statement sequence! Why? The if-else statement is flexible: it can have different conditions for each ‘if’ statement; also each condition can have (different)

Instead of starting by dissecting the given obfuscated program, let me start from the original program and explain how one can arrive at the obfuscated code (because that’s the way almost all obfuscated programs are written). Here is the original program: const char * str = “Happy birthday to you\n”; int main(){ const char name[50]; gets (name); printf(“ %s %s %. 15s%s %s”, str, str, str, name, str); } The idea is to print the string “Happy birthda

c m y k 85www. openITis. com | LINUX For YoU | AprIL 2008 W hen we hear of some strange algorithms with names like ‘Dijkstra’s shortest path’, ‘Markov’s string replacement’ or ‘Sieve of Eratosthenes’, we usually dislike the arcane and dry solutions they describe. However, such algorithms can have interesting applications or can provide some unusual solutions that are not possible with the straightforward solutions we often arrive at based on common sense. We’ll explore ‘Markov’s string replacement’ algorithm in this article. What this algorithm does is simple string rewriting based on a set of rules. Let’s look at an interesting application of this algorithm: converting a binary to unary by string replacement, by applying a set of rules. The idea described here is from en. wikipedia. org/wiki/Markov_algorithm Let us look at the rules first: • Rule 1: “#0” => “0##” • Rule 2: “1” => “0#” • Rule 3: “0” => “” • Rule 4: “#” => “1” The symbol ‘=>’ stands for ‘replace with’.
