A systematic approach to software peripherals for embedded systems

System Architecture for Software Peripherals

“…The idea of software peripherals was proposed in [1,4]. The focus in [1,4] was on proposing the idea of software peripherals, its usefulness and estimating the processor overhead imposed by software peripherals.…”

“…The focus in [1,4] was on proposing the idea of software peripherals, its usefulness and estimating the processor overhead imposed by software peripherals. This work used a simplified model of peripherals to calculate the processor utilization for each peripheral in isolation.…”

“…Software peripherals [1,3] have been proposed to meet the challenges of flexibility and cost in processor-peripheral platforms, while still meeting performance requirements. Software peripherals emulate the implementation of peripherals in software (processor) with minimal hardware support, if any.…”

“…

Software peripherals [1] have been proposed as a design alternative to traditional peripherals. We propose a software architecture, design methodology and scheduling scheme for implementing software peripherals on general purpose processors, with fast context switch and high resolution timers.
