Intel Dynamic Acceleration technology (IDA)
Intel Dynamic Acceleration technology (IDA) is a feature that boosts CPU performance when the CPU is running single-threaded applications. This is achieved by temporary increasing frequency of one CPU core when another CPU core is idle, i.e. when the second CPU core is in Deep Sleep or lower power state. How much the frequency is increased depends on front-side bus speed of the CPU:
This feature was introduced in Intel Core 2 Duo Mobile microprocessor family and is applicable only to dual-core CPUs. Quad-core processors incorporate Dual Dynamic Acceleration feature, which works similar to IDA. Newer Intel microprocessors based on Nehalem core utilize improved version of IDA called Turbo Boost Technology.
