Two more generations of the Cortex processors, R5 and R7, were announced by ARM by end January. That ARM is the leader in most things mobile as also a large slice of embedded stuff is indisputable. These two are clear signs of what's to come. They are positioning these at 3G and 4G, LTE use as well as mass storage devices, in-car entertainment applications as well as industrial equipment. The R5 enhances features of R4, it predecessor. low latency peripheral port (LLPP) improves peripheral I/O. R5 also has am accelerator coherency port that helps cache coherence.
R7 add substantial number new features. This should improve performance significantly over the older members of the family. Out of order execution, superscalar execution, dynamic register renaming, better branch prediction, hardware assist for floating point calculations, including divide are some of these features.These processors, according to ARM, should take care of real time processing needs of the future handsets.
