Translation Lookaside Buffers

Translation Lookaside Buffers The virtual->physical address translation operation sits on the critical path between the CPU and the cache. If every request for a memory location emanating from the processor required one or more accesses to main memory (to read page...

Measuring and improving cache performance

Measuring and improving cache performance Cache Performance Average memory access time is a useful measure to evaluate the performance of a memory-hierarchy configuration. It tells us how much penalty the memory system imposes on each access (on average). It can...

Classification of Sound

Classification of Sound In physics, sound is a vibration that propagates as a typically audible mechanical wave of pressure and displacement, through a medium such as air or water. In physiology andpsychology, sound is the reception of such waves and their perception...

objects in c++

Objects in C++ Define C++ Objects: A class provides the overview for objects, so an object is created from a class. We declare objects of a class with exactly the same order of declaration that we declare variables of basic types. Following statements declare two...

Particle in a one dimensional box

Particle in a one dimensional box Schrodinger Equation for a particle-in-a-box: Confine a particle to a finite region in which it has no potential energy. Its energy is only due to motion—-kinetic energy. It experiences no potentials due to any external force,...

direct memory access

direct memory access During any given bus cycle, one of the system components connected to the system bus is given control of the bus. This component is said to be the master during that cycle and the component it is communicating with is said to be the slave. The CPU...
