Performance trends in high-end processors

摘要: Based on a first order cycle time model performance trends and limits are projected for both bipolar CMOS processors. The key in identifying is the understanding of pivotal factors at any given stage technology progression. One such parameter physical area processor. In coming technologies there will be opposite demands placed system's stemming from need to reduce proportion interconnection capacitance send signals across Contrary usual perception, delays resulting wiring decrease if processor increases, while minimization signal travel times favors reducing area. system size tradeoff case processors primarily determined by power density, sizes wirability requirements. To achieve full potential CMOS, interconnections have carefully planned. room temperature uniprocessors shown very similar. highest horizon liquid nitrogen CMOS. Alternate technologies, based III-V compound devices, or more exotic quantum structures, not expected play role future general-purpose high-end systems. >
