    In almost all processor, L2 cache associativity is some power of 2 (L1 is generally direct mapped  or some low power of 2). Although in Alpha 21164 super-scalar processor L2 cache (96KB) was 3-way set associative. Which doctrine had convinced the architect of alpha 21164 processor to not to have the associativity some power of 2 ?

    While designing a dc- dc high power converter with fixed input voltage and I want to know, what are the factors which decides the amount of current drawn from the source by a dc-dc converter ? How can I improve the current drawn from the source so that maximum energy could be transferred through the power converter?

    For crystalline materials containing more than one phase, e.g. for mineralogical samples but also for some technical products like steel or Ti-Al, is it meaningful to display the microstructure by IPF or Euler colouring for all phases at the same time, or is it not required to generate single maps for at least all phases displayed by different colour keys?
