  • Patent number: 10656696
    Abstract: Systems, apparatuses, and methods for reducing chiplet interrupt latency are disclosed. A system includes one or more processing nodes, one or more memory devices, a communication fabric coupled to the processing unit(s) and memory device(s) via link interfaces, and a power management unit. The power management unit manages the power states of the various components and the link interfaces of the system. If the power management unit detects a request to wake up a given component, and the link interface to the given component is powered down, then the power management unit sends an out-of-band signal to wake up the given component in parallel with powering up the link interface. Also, when multiple link interfaces need to be powered up, the power management unit powers up the multiple link interfaces in an order which complies with voltage regulator load-step requirements while minimizing the latency of pending operations.

    Abstract: Systems, apparatuses, and methods for performing transmit equalization at a target high speed are disclosed. A computing system includes at least a transmitter, receiver, and a communication channel connecting the transmitter and the receiver. The communication channel includes a plurality of lanes which are subdivided into a first subset of lanes and a second subset of lanes. During equalization training, the first subset of lanes operate at a first speed while the second subset of lanes operate at a second speed. The first speed is the desired target speed for operating the communication link while the second speed is a relatively low speed capable of reliably carrying data over a given lane prior to equalization training. The first subset of lanes are trained at the first speed while feedback is conveyed from the receiver to the transmitter using the second subset of lanes operating at the second speed.
