Abstract: One embodiment includes a computing device including peripheral component bus interfaces for connection to a peripheral component bus, a first integrated circuit (IC) chip comprising a processor to initiate a register setup process of the device, a second IC chip including a tile processor including multiple tiles, each tile including at least a processing core configured to generate requests to at least one of the peripheral component bus interfaces, steering configuration registers to store steering configuration data, and steering logic to steer the generated requests responsively to the steering configuration data in the steering configuration registers, and steering register setup circuitry including a multicaster and a register setup memory, wherein the processor is configured to write the steering configuration data to the register setup memory, and the multicaster is configured to multicast the steering configuration data written to the register setup memory to the steering configuration registers of the tiles.

Abstract: An integrated circuit and method are described for compensating for voltage droop on an integrated circuit using a power supply voltage monitoring circuit and a high-resolution adaptive clock stretching circuit. In some example embodiments, the method includes monitoring power supply voltage on an integrated circuit, detecting a voltage droop such as a dynamic loss of power supply in the integrated circuit, and stretching a current clock cycle, according to the detected voltage droop, to provide more time for logic on the integrated circuit to complete before a next clock cycle.
