Abstract: Techniques for calibrating interleaved analog-to-digital converter (ADC) arrays are presented. A transceiver comprises an ADC component comprising an array of interleaved sub-ADCs, and an auxiliary path associated with an auxiliary sub-ADC used to facilitate calibrating a sampling array by comparing the auxiliary path signal to signals of the sub-ADCs in the array. A calibration component employs a phase-interpolator and analog delay lines to adjust the auxiliary sub-ADC to enable the auxiliary sub-ADC to be lined up to any one of the sampling instants of the sampling array. The calibration component compares the auxiliary signal to sub-ADC signals, determines path differences between the sub-ADC paths based on the comparison results, and calibrates the sub-ADCs and sub-ADC paths to reduce the path differences to mitigate distortion in a digital stream produced from combining the digital substreams produced by the sub-ADCs in the array.

Abstract: Systems and methods of mitigating precursor ISIs for communication channels having time-variant precursor channel responses using digital circuit designs. A phase adaptation circuit is utilized in a receiver and configured to generate a phase control signal responsive to an input signal and based on the current precursor channel response. The phase control signal controls the phase shift of a recovered clock to a position where the precursor ISI at h(−1) is minimized. The phase control signal corresponds to a “feed-forward equalization (FFE) first tap weight” obtained via a digital least-mean-square (LMS) process.

Abstract: Various aspects provide for generating a clock signal for a hold latch. A latch pulse generator generates a pulse clock signal based on a first clock signal associated with a first flip-flop component and a second clock signal associated with a second flip-flop component. A hold latch component receives the pulse clock signal generated by the latch pulse generator and generates a data signal that is transmitted to the second flip-flop component.

Abstract: A system and method are provided for simplifying load acquire and store release semantics that are used in reduced instruction set computing (RISC). Translating the semantics into micro-operations, or low-level instructions used to implement complex machine instructions, can avoid having to implement complicated new memory operations. Using one or more data memory barrier operations in conjunction with load and store operations can provide sufficient ordering as a data memory barrier ensures that prior instructions are performed and completed before subsequent instructions are executed.
