Xilinx unveils ARM-based architecture
9 June 2010
Programmable Logic
Xilinx has unveiled the architecture for a new Extensible Processing Platform based on the ARM Cortex-A9 MPCore processor.
The platform enables system architects and embedded software developers to apply a combination of serial and parallel processing to address the system requirements presented by the global demand for embedded systems to perform increasingly complex functions.
A software-centric development flow is enabled by a processor-centric approach which presents a full processor system – including caches, memory controllers and commonly used connectivity and I/O peripherals – that boots and can run a variety of operating systems at power-up, such as Linux, Wind River’s VxWorks and Micrium’s uC-OSII. The ARM architecture and its connected community ecosystem further maximise productivity for developers of embedded systems, while performance is achieved by Xilinx architecting the subsystem around ARM’s dual-core Cortex-A9 MPCore processors, each running at up to 800 MHz, combined with the parallel-processing capabilities of Xilinx’s high-performance, low-power 28-nanometre programmable logic.
The programmable logic is tightly coupled with the processor system through the high-bandwidth AMBA-AXI interconnects to accelerate key system functions using off-the-shelf and/or custom IP. This architectural approach addresses common performance bottlenecks between these parallel and serial computing environments, memory and I/O. It also gives the processor system configuration control of the programmable logic, including dynamic reconfiguration.
Software developers can leverage their existing system code based on ARM technology and utilise off-the-shelf open-source and commercially available software component libraries. Because the system boots an OS at reset, software development can get under way quickly within familiar development and debug environments using tools such as ARM’s RealView development suite and related third-party tools, Eclipse-based IDEs, GNU, the Xilinx Software Development Kit and others.
This new platform is targeted at leading-edge developments in technology areas requiring multifunctionality and real-time responsiveness, such as automotive driver assistance, intelligent video surveillance, industrial automation, aerospace and defence, and next-generation wireless.
