RADAR plays an increasingly significant part
in many applications, which are often mobile
and have strict SWaP-C, performance, and
upgradability requirements. The RFSoC provides
an integrated monolithic device that addresses
the SWaP-C demands and offers significant
performance and the ability to implement future
system requirements as standards evolve.

Local storage of data enables higher system performance
to support these Block RAM and UltraRAM elements
within the programmable logic. Block RAM is ideal for
storing data, such as buffers, memories, and FIFOs,
between algorithmic states. UltraRAM is designed to
replace external memories when larger quantities of
data need to be stored. UltraRAM blocks are larger
than Block RAM at 4K by 72 bits, providing 288Kb per
block, compared to 36Kb for Block RAM. Architecturally,
UltraRAM blocks can be cascaded to create large internal
memories used to store data captured from the ADC
or output on the DAC. Within the RFSoC device range,
UltraRAM capacities vary between 13.5Mb and 22.5Mb,
depending on the device.
Crucially, this integration of significant RF front-end elements
into the SoC does not remove the need for RF designers
from the design flow. Instead, the RFSoC brings the RF
designer into the heart of the system design, enabling
them to specify the desired RF behavior and take an active
part in the design. This allows quick capturing of their
RF knowledge and a complete subsystem's handoff for
integration to the broader design team. Of course, the RF
engineer also supports the wider design team in addressing
the RF challenges as they arise in integration and playing a
more active part in creating the integrated solution.
