Abstract: An apparatus is described. The apparatus includes logic circuitry to multiplex on a data bus a first data burst, a second data burst, a third data burst and a fourth data burst having different respective base target addresses that respectively target a first memory rank, a second memory rank, a third memory rank and a fourth memory rank. A first data transfer for the first data burst occurs on a first edge of a first pulse of a data strobe signal for the data bus and a second data transfer for the second data burst occurs on a second edge of the first pulse of the data strobe signal. A third data transfer for the third data burst occurs on a first edge of a second pulse of the data strobe signal for the data bus and a fourth data transfer for the fourth data burst occurs on a second edge of the second pulse. The second pulse immediately follows the first pulse on the data strobe signal.

Abstract: Methods and apparatus for Cross DRAM DIMM sub-channel pairing. Memory channels on a memory controller or System on a Chip (SoC) are segmented into two subchannels, each including Command and Address (C/A) signals, DQ (data) lines. Under different solutions the two subchannels may share a command-bus clock or use separate command-bus clocks. Some approaches use subchannels from different memory channels to provide the C/A and DQ lines for two subchannels to a given DIMM. One solution implements an additional command-bus clock on the DIMM connector repurposing existing MCR pins to provide command-bus clock signals to a Registered Clock Driver (RCD) to allow the subchannels to be fully independent. Another solution is the pair every other DRAM controller to the same command-bus clock. Other solutions employ Skip-1, Skip-2, and Skip-3 configurations under which the clocks for the DDR-IO circuitry are not logically co-located with the subchannel IO circuitry.

Abstract: Methods, apparatus, and software and for hardware microservices accelerated in other processing units (XPUs). The apparatus may be a platform including a System on Chip (SOC) and an XPU, such as a Field Programmable Gate Array (FPGA). The FPGA is configured to implement one or more Hardware (HW) accelerator functions associated with HW microservices. Execution of microservices is split between a software front-end that executes on the SOC and a hardware backend comprising the HW accelerator functions. The software front-end offloads a portion of a microservice and/or associated workload to the HW microservice backend implemented by the accelerator functions. An XPU or FPGA proxy is used to provide the microservice front-ends with shared access to HW accelerator functions, and schedules/multiplexes access to the HW accelerator functions using, e.g., telemetry data generated by the microservice front-ends and/or the HW accelerator functions.

Abstract: Reliability and performance of a data center is increased by processing telemetry data in a network device in the data center. A Telemetry Correlation Engine (TCE) in the network device correlates host level telemetry received from a compute node with low-level network device telemetry collected in the network device to identify performance bottlenecks for microservices based applications. The Telemetry Correlation Engine processes and analyzes the telemetry data from the compute node and network statistics available in the network device.

Abstract: A method and apparatus for increasing performance of Data Encryption Standard (DES) and Triple DES (3DES) cipher operation is provided. A critical path through a plurality of rounds in a multi-round cycle to perform a cipher operation is reduced by reducing the number of exclusive OR (XOR) operations in the critical path. An R state element is expanded to 48-bits and each round stage uses the 48-bit expanded R state element which results in a reduction of the number of XOR operations to one per round in the cipher operation plus one additional XOR operation per cipher operation. In addition logic organization is symmetric which further increases the overall performance of DES and 3DES.
