An integrated circuit includes an array of interconnected programmable logic elements () each logic element performing data processing control by a configuration. The logic elements may be part of a field programmable gate array. Embedded within the array are a plurality of dedicated communication interface circuits () providing access to one or more shared communication channels () to provide intra-array communication. Communication transactions between functional unit () are multiplexed (e.g. time-division-multiplexed) together to share a shared communication channel provided within the array.

Communication within an integrated circuit including an array of interconnected programmable logic elements

An integrated circuit () comprising an array () of interconnected configurable logic elements (), such as an FPGA array, is provided. The logic elements are used to form a power controller () which separately controls the power state of different regions of the array. Each region of the array contains one or more logic elements. Each region has a corresponding region controller () responsive to one or more power signals generated by the power controller to switch that region into the requested power state.

A diagnostic mechanism for an integrated circuituses a radio interface circuitto provide communication between an external diagnostic deviceand one or more diagnostic circuitswithin the integrated circuit. The use of a radio communication link for diagnostic data and control reduces the required pin count for the integrated circuit
