Thanks to the large number of processing elements, these systems potentially allow a better management of periodic workloads and can react faster to external, aperiodic events. Multiprocessor systems-on-chip, composed of several processing elements, including multiple general-purpose cores, and on-chip memories, have become the standard for implementing embedded systems. Ferrandi, in Rugged Embedded Systems, 2017 2 Case Study: A Field Programmable Gate Array Prototype for the Validation of Real-Time Algorithms Clearly, this blurs the boundary between compiler research and traditional high-level synthesis, another area under intense investigation (Detton and Wawrzynek, 1999) Extending this approach of exposing the inner architecture of a processor to the compiler even further results in the possibility of more fine-grained reconfigurable computing techniques using field programmable gate arrays (Luk et al.,). Relying on compilation is possible because the hardware consists of a simple regular array of interchangable processing units. These approaches eliminate traditional instruction-set interfaces and instead rely heavily on compilation to directly customize the hardware to a particular application. (1997) can be considered radically different forms of multiprocessor architecture. Very coarse-grained programmable logic devices such as Chess (Marshall et al., 1999) or the RAW machines proposed by Waingold et al. With the introduction of the single-chip multiprocessor (Olukotun et al., 1996), the dividing line between research into high-performance system architectures and high-performance processors is becoming blurred.
Multi processing operating system examples software#
The extraction of coarse-grained parallelism from a software description and, indeed, the study of languages used to describe parallel software are a flourishing area of research. In addition, multiprocessor systems have shown the ability to improve single-program performance significantly for certain applications containing easily parallelized loops. Multiprocessor systems are being used successfully today to improve performance in systems running multiple programs concurrently.
