Abstract: The present disclosure describes programmable logic that may be operated in a turbo processing mode to cause an ongoing operation to be completed faster than a scheduled completion time. With at least some of the remaining time to the scheduled completion time, power savings may be realized by operating the programmable logic into a deep sleep mode, where configuration memory associated with the programmable logic may be set to a suitable voltage level as to not cause data loss at lower or zero voltage levels but otherwise realize power savings relative to an amount of power consumed during average processing operations.

Abstract: An integrated circuit device that includes programmable logic circuitry that includes a plurality of regions each configured to operate at different voltage levels. The regions may be separated by level shifters that enable communication between the different voltage level regions. The integrated circuitry may also include software that performs voltage aware placement and routing for a user register-transfer level design, and may direct logic to regions according to voltages defined for the regions.

Abstract: Systems or methods of the present disclosure may provide efficient power consumption for programmable logic devices based on reducing guardband voltages. A programmable logic device may include circuit monitors to mimic critical paths of an implemented circuit design and generate timing information based on the critical paths. A controller on the programmable logic device may adjust the voltage guardband based on the timing information.

Abstract: Systems or methods of the present disclosure may provide for gradually adjusting a frequency of a clock signal. When transitioning from a configuration mode to a user mode, a clock of an integrated circuit (e.g., a field-programmable gate array or FPGA) may quickly (e.g., instantaneously) switch from a low configuration mode frequency to a high user mode frequency. This rapid increase in clock frequency may cause an inrush current and corresponding current-resistance voltage (IR) drop. To reduce or avoid the inrush current and IR drop, a frequency of the clock may be gradually ramped up from the configuration mode frequency to the user mode frequency.

Abstract: A reticle-stitched integrated circuit is provided. The reticle-stitched integrated circuit extends over a first die area and a second die area of an integrated circuit wafer. While individually the first die area and the second die area are within their respective reticle limits, collectively the first die area and the second die area exceed the reticle limit. A first layer of the reticle-stitched integrated circuit may have communication wires that remain exclusively in only one of the first die area and the second die area. A second layer of the reticle-stitched integrated circuit may have communication wires that overlap the first die area and the second die area, thereby allowing communication between the two die areas and enabling the reticle-stitched integrated circuit to exceed the limit of the reticle.

In one embodiment, a hardware processor includes a plurality of physically separate dies, and an interconnect to electrically couple the plurality of physically separate dies together. In another embodiment, a method to create a hardware processor includes providing a plurality of physically separate dies, and electrically coupling the plurality of physically separate dies together with an interconnect.

Abstract: A digitally communicative circuit may use standardized interfaces for connection and communication with other circuit components. Such digitally communicative circuit may benefit from using wider variety of interconnect schemes with the respective interfaces for transmission and reception of data. Some chiplets may communicate using a high data bandwidth interface while other chiplets may communicate using interfaces with lower data bandwidth. Alternate interface is introduced that may facilitate scaled communication with Advanced Interface Bus 2.0 without translation circuitry and with different data bandwidth.

Abstract: Embodiments herein relate to systems, apparatuses, or techniques for using an optical physical layer die within a system-on-a-chip to optically couple with an optical physical layer die on another package to provide high-bandwidth memory access between the system-on-a-chip and the other package. In embodiments, the other package may be a large optically connected memory device that includes a memory controller coupled with an optical physical layer die, where the memory controller is coupled with memory. Other embodiments may be described and/or claimed.

Abstract: An integrated circuit device includes multiple microbumps and a top programmable fabric die including a first programmable fabric and a first microbump interface coupled to the multiple microbumps. The integrated circuit device also includes a base programmable fabric die having a second programmable fabric and a second microbump interface coupled to the first microbump interface via a coupling to the multiple microbumps. The top programmable fabric die and the base programmable fabric die have a same design. Moreover, the top programmable fabric die and the base programmable fabric die are arranged in a three-dimensional die arrangement with the top programmable fabric die flipped above the base programmable fabric die.

Abstract: A request associated with a particular cache record is generated to be sent to a system component associated with a cache bank over an interconnect. A wake-warn signal is sent over a dedicated wake-warn channel to indicate to the system component that the request is to arrive. Wake-warn signals cause a disabled clock to be ungated to an enabled state. The request is then sent to the system component.

Abstract: Embodiments of the present disclosure describe techniques and configurations to reduce power consumption using unmodified information in evicted cache lines. A method includes identifying unmodified information of a cache line stored in a cache of a processor, tracking the unmodified information using a bit vector comprising one or more bits to indicate the unmodified information of the cache line, and selectively suppressing a write operation or send operation for the unmodified information of the cache line that is evicted from the cache to an input/output (I/O) component coupled to the cache, the selective suppressing being based on the one or more bits, and the I/O component being an outer component external to the cache. Other embodiments may be described and/or claimed.
