Memory Buffer Chips: Satisfying Amdahl’s Law To Sustain Moore’s Law


Moore’s Law, the observation that the available transistors in an integrated circuit doubles every two years, has driven the semiconductor and IT industries to unparalleled growth over the last 50+ years. These transistors have been used in CPUs to increase the number of parallel execution units and instruction fetches, expand the levels of on-chip cache (and overall capacity), support spe... » read more

The Limits Of Parallelism


Parallelism used to be the domain of supercomputers working on weather simulations or plutonium decay. It is now part of the architecture of most SoCs. But just how efficient, effective and widespread has parallelism really become? There is no simple answer to that question. Even for a dual-core implementation of a processor on a chip, results can vary greatly by software application, operat... » read more
