How to use in-sentence of “superscalar”:
– Branch predictors are important in today’s modern, superscalar processors for achieving high performance.
– Now modern CPUs have multiple parallel execution units, referred to as scalar or superscalar design.
– Most superscalar CPUs are also pipelined, but it’s possible to have a non-pipelined superscalar CPU or a pipelined non-superscalar CPU.
– While hardware advances will allow for more functional units per CPU core, the problem of checking instruction dependencies increases to a limit that the achievable superscalar dispatching limit is somewhat small.
– Multithreading is similar in concept to multitasking but is implemented at the thread thread level of execution in modern superscalar processors.
– As of 2008, all general-purpose CPUs are superscalar, a typical superscalar CPU may include up to 4 ALUs, 2 FPUs, and two SIMD units.
– By the late 1980s, superscalar designs started to enter the market place.
– This technique allows superscalar CPUs to execute instructions from different programs/threads simultaneously in the same cycle.
