“…SoCs grow in complexity as an increasing number of independent applications are integrated on a single chip [9,50,55,146,177]. In the area of portable consumer systems, such as mobile phones, the number of applications doubles roughly every 2 years, and the introduction of new technology solutions is increasingly driven by applications [80,88].…”

“…The high-level models are thus not able to guarantee that the application requirements are met. Instead, we need to develop the technology that allows applications to be easily composed into working systems, independent of other applications in the system [9,77,90,146].…”

“…Embedded systems are seeing an increasing number of applications integrated on a single chip [1][2][3][4][5]. A large part of the applications are from the signal-processing domain [1,4], which is also the focus of this work.…”

“…Thus, a composable platform ensures that the behaviour of one application is independent of all other applications. Traditionally, composability placed strict limitations on the applications [9,2], unsuitable for e.g. the consumer-electronics domain.…”

a b s t r a c tMulti-Processor Systems on Chip (MPSoC) run multiple independent applications, often developed by different parties. The applications share the hardware resources, e.g. processors, memories and interconnect. The sharing typically causes interference between the applications, which severely complicates system integration and verification. Even if the applications are verified in isolation, the system designer must verify the combined behaviour, leading to an explosion in design complexity. Composable MPSoCs have no interference between applications, thus allowing independent design and verification. For an MPSoC to be composable, all the hardware resources must offer composability. A particularly challenging resource is the processors, often purchased as off-the-shelf intellectual property.In this work we present the design and implementation of CompOSe, a light-weight (only 1500 lines of code) composable operating system for MPSoCs. CompOSe uses fixed-size time slices, coupled with a composable scheduler, to enable composable processor sharing. Using instances of ARM7, ARM11 and the Xilinx MicroBlaze we experimentally demonstrate the ability to provide temporal composability, even in the presence of dynamic application behaviour and multiple use cases. We do so using a diverse set of processor architectures, without requiring any hardware modifications. We also show how CompOSe allows slack to be distributed within and between applications through a novel two-level scheduler and slack-distribution system.
