Abstraction Layer
The LogiCORE IP for FlexRay is a controller that implements the
FlexRay communication protocol as defined in the FlexRay Protocol
Specification v2.1 Rev A. It provides functionalities such as:
• Data rate of up to 10 Mbps
• Single Communication Channel
• Scalable synchronous and asynchronous data transmission
• Configurable payload length up to a maximum of 256 bytes
• Configurable receive and transmit buffers for storage of up to
128 messages each
• Frame ID, cycle counter and message ID based receive filtering
• OPB and PLB interface suitable with single and burst support
• Variable OPB and PLB interface clock
• Supported in CORE Generator software for stand alone
applications and in EDK for MicroBlaze-based ECU applications
Availability of the FlexRay Driver for the Xilinx MicroBlaze
32-bit processor enables easy access to the full suite of
Vector’s FlexRay software solution developed according to
the AUTOSAR specification.
• The FlexRay Driver handles the hardware-specific
characteristics of the Xilinx FPGA and acts as an abstraction
layer to other software offerings available through Vector,
covering the signal, diagnostic and transport layer as well
as the network support and node management
• Full support of the FlexRay synchronous layer for the
driver as well as support of the FlexRay asynchronous
layer for the protocol stack and the application
• Full integration into the Vector tool chain including the
DaVinci Network Designer for FlexRay supporting multiple
FIBEX revisions, the development & analysis tool with
real-time support, as well as measurement and calibrations
of ECUs
