Systems and methods for RF communication between processors
Embodiments include systems and methods for integration of RF components onto a single die with functional processing circuitry. For example, one integrated circuit may comprise multiple processors that can communicate there between by way of Radio Frequency (RF) transmission. The processors may also communicate with slave devices by way of radio frequency. Transmission and reception may be at frequencies in a band hitherto unused in computing devices and their peripherals.
