Hardware Platform

SoCLib

SoCLib is the library with built-in support in DSX. This library offers a virtual prototyping environment for hardware MP²-SoC platforms. As a codesign tool, DSX needs an hardware component library for the hardware part of the design.

Openness and good tools support of the SoCLib library makes it a good candidate for DSX usage. DSX uses SoCLib as an hardware platform basic-block provider, and a benchmark environment.

DSX has its own high-level platform representation, made of SoCLib IP-cores. Users can assemble a platform with the provided API and then:

• use it as a mapping target for an application,
• generate a SystemC netlist of matching SoCLib components,
• call the SoCLib build-system to obtain a simulator from the generated netlist.

Architecture definition

An architecture definition is made of:

• an Architecture object.
• some create calls, corresponding to some IP core in SoCLib, with its implementation and Metadata. Metadata defines ports of the component, and associated signals types.
• connection directives between ports.

Note

As connections are directly done between ports, DSX high-level soclib netlists create signals implicitly. This leverages most tedious part of the netlisting.
