Abstract

The new multicore processor architectures bring new difficulties to software development. Amongst these difficulties is the need of execution flow synchronization to assure correct shared memory accesses. This synchronization usually is done using locks or mutexes, but both structures are inefficient and hard to use. Transactional memories are an alternative for synchronizing a parallel software, providing a simple abstraction and assuring data consistency.Low energy consumption is a very desirable characteristic in computing systems, since it allows embedded systems to work for longer time and makes cooling easier in bigger computers. This work investigates the problem related to the energy consumption in the application of software transactional memory systems. After understanding the influence of these systems on the energy consumption, it will be possible develop a transaction memory model optimized for low power consumption. (AU)
