Layerscape architecture supports a consistent programming framework across the architecture using standard C/C++ languages
Embedded processing application company Freescale Semiconductor has expanded its third-generation QorIQ portfolio with Layerscape system architecture.
The new core-agnostic software-aware framework meet the requirement of flexibility and scalability of network infrastructure OEMs as they adopt to connected devices, massive datasets, tight security, real-time service and unpredictable network traffic patterns.
The Layerscape architecture is a fundamental new approach to networking system architectures that puts software and programmability at the forefront.
It also modularises packet acceleration and forwards operations from high-level routing decisions, streamlines interaction between the layers, leverages a synchronous run-to-completion model and supports a consistent programming framework across the architecture using standard C/C++ languages.
The new architecture leverages, builds upon Freescale's expansive networking IP portfolio and also extends the QorIQ Data Path Acceleration Architecture (DPAA).
Freescale's modular Layerscape architecture consists of three independent layers, a general-purpose processing layer, an accelerated packet processing layer and an express packet I/O layer. This allows the company to design QorIQ devices with expanded, reduced or removed layers as needed.
The company has also introduced the first two QorIQ product families based on the Layerscape architecture, the LS-1 and LS-2.
The LS-1 and LS-2 products include dual ARM Cortex processor cores, virtualisation support, advanced security, an array of advanced interconnects, a common ISA and software- and pin-compatibility for simple and smooth application migration between the two families.
