Title: Wireless communication system within a system on a chip

Abstract: A communication system (8) for transmitting data between cores (10) embedded in an integrated circuit on a silicon chip (12). Communication system (8) includes transmitter circuitry (24) for wirelessly transmitting data between cores (10) and receiver circuitry (26) for wirelessly receiving the transmission of data from other cores. Both transmitter circuitry (24) and receiver circuitry (26) may include of a phase-locked loop circuit (28, 30) having a voltage-controlled oscillator (36). Each core (10) may transmit and receive data on a unique frequency with respect to other cores embedded in an integrated circuit on a silicon chip (12) or transmit and receive data on the same frequency as other cores embedded in an integrated circuit on a silicon chip (12). Groups of cores (17) may share transmitter and receiver circuitry (24 and 26).
