This chapter discusses optimization techniques for C and C++ code developed for real-time and embedded systems. When arrays of structures are involved, the compiler performs a multiply by the structure size to
most of the optimization techniques that are performed by a compiler involve a tradeoff between execution speed and code size. Your program can be made either faster or smaller, but not both. In fact, an improvement in one of these areas can have a negative impact on the other. It is...
I see that when it comes to the performance several techniques / tricks can be combined, like code optimization(s) ( unrolling ), application of new sets of SIMD instructions and correct usage of L1, L2 and L3 cache lines of some CPU ( ideally a 3-layred Loop Blocking optimization ...
In this paper we present code generation and optimization techniques for a Java-to-C compiler. Also our compiler fully supports Connected Limited Device Configuration (CLDC) 1.0 API's. Moreover, our Java-to-C compiler translates for in Java into for in C in order to get better performance ...

single Epiphany core. The programs were first implemented as a naïve implementation and then were re-written to take advantage of optimization techniques like loop unrolling, circular buffer elimination, etc. In addition, optimizer command line options were chosen to further enhance the optimization....

How can I optimize C++ code in an iOS app with Objective-C? Optimizing C++ code in an iOS app with Objective-C involves a combination of general C++ optimization techniques and specific strategies for iOS development. Some general techniques include using const references, minimizing copying, and...
