The A429-RxTx IP core is a multichannel transmitter (Tx) and receiver (Rx) compliant to the ARINC 429 standard. Developed according to DO-254 ED-80 guidelines and field-proven in many civilian and military avionics systems, the core is highly reliable and ready for aviation applications. The core is designed to enable independent control of multiple Rx and Tx channels with minimum overhead for the host processor. The number of Rx and Tx channels is configurable at synthesis time. Frames are stored in 32-bit wide FIFOs of synthesis-time configurable depth. The core provides access to the FIFOs and to its status and control registers via a generic 32-bit wide interface. The data-rate and parity mode for each channel can be independently set, and receiving channels can be programmed to filter data based on the label and/or the SDI fields of the incoming frames. The core reports status and errors via its status registers, but also via a rich set of maskable interrupts.
The A429-RxTx core can be mapped to any Intel FPGA device (provided sufficient silicon resources are available) and optimized to suit the particular project’s requirements. The core occupies approximately 2,000 ALMs for each Rx and Tx pair. Please contact CAST to discuss resource utilization and performance for your application and target device.
