Description

The Zynq and FMCOMMS2/3/4 Transmitter Configuration block connects your hardware logic to the FMCOMMS2/3/4 radio transmitter hardware. In simulation, this block provides optional ports for center frequency and gain, which the SoC Builder tool maps to hardware pins. The block does not connect to the radio hardware from simulation.

Examples

Packet-Based ADS-B Transceiver

Packet-Based ADS-B Transceiver

Packet-based systems are common in wireless communications. Data is received over the air and is decoded as discrete packet data on a compute device. For given system requirements, it is difficult to design a system and implement directly on SoC as it often involves long iterations of debugging and integration on hardware since hardware effects are difficult to account for at design time. In this example, you will design packet-based airplane tracking application based on Automatic Dependent Surveillance Broadcast (ADS-B) standard, partitioned between FPGA and embedded processor. Unlike traditional methods, you will simulate the application design with memory interface before implementation on hardware using SoC Blockset™ to shorten development time. You will then validate the design on hardware by automatically generated code from the model.

Parameters

expand all

The Zynq and FMCOMMS2/3/4 Transmitter Configuration block supports up to two channels to send data. Use the Channel mapping parameter to indicate whether to use a single channel or dual channels. For each channel, you can set the Gain (dB) parameter independently, or you can apply the same setting to all channels. If you select direct digital synthesis (DDS) transmission for the Data source select parameter, you can also set all DDS-based parameters independently. All other parameter values are applied to each channel in use.
