MPSoCs

	Pam-SoC keywords MPSoC performance prediction. features PAM-SoC is a light semi-static performance prediction toolchain that computes system-level performance estimations for applications running on MPSoCs. PAM-SoC is based on Pamela, a static performance prediction methodology for general purpose parallel platforms (GPPPs). By coupling an application model with the target machine model, Pamela computes the lower bound of the execution time of the application on the target architecture. To address the specifics of MPSoCs, PAM-SoC includes new techniques for machine modeling and tools for gathering memory behavior statistics. In its prediction, PAM-SoC trades accuracy for estimation speed: in cases when cycle-accurate simulation would take tens of minutes, application behavior can be estimated in (tens of) seconds. Thus, PAM-SoC can be part of the design flow of an MPSoC platform, for either application or architecture tuning.
