Power dissipation has become a critical design metric in microprocessor-based system design. In a multi-core system, running multiple applications, power and performance can be dynamically traded off using an integrated power management (PM) unit. This PM unit monitors the performance and power of each core and dynamically adjusts the individual voltages and frequencies in order to maximize system...
Performance analysis of microprocessors is a critical step in defining the microarchitecture, prior to register-transfer-level (RTL) design. In complex chip multiprocessor systems, including multiple cores, caches and busses, this problem is compounded by complex performance interactions between cores, caches and interconnections, as well as by tight interdependencies between performance, power and...
In the past, processor design trends were dominated by increasingly complex feature sets, higher clock speeds, growing thermal envelopes and increasing power dissipation. Recently, clock speeds have tapered and thermal and power dissipation envelopes have remained flat. However, the demand for increasing performance continues which has fueled the move to integrated multiple processor (multi-core)...
