    摘要: A method and apparatus for voltage regulation uses, in one aspect, worst-case supply voltages specific to the process split of the integrated device at issue. In another aspect, a two-phase voltage regulation system and method identifies the characterization data pertinent to a family of integrated circuit devices in a first phase, and identifies an associated process split of a candidate integrated circuit device in a second phase. The characterization data from the first phase is then used to provide supply voltages that correspond to target frequencies of operation for the candidate device. In another aspect, a hybrid voltage regulator circuit includes an open loop circuit which automatically identifies the process split of the integrated circuit device and allows a regulator to modify supply voltage based on characterization data specific to that process split, and a closed loop circuit which fine-tunes the supply voltage. In one embodiment, the closed-loop circuit includes a critical path replica for providing estimated frequencies of operation necessary for a critical path in the integrated circuit device. A ring oscillator circuit may be used in one embodiment in the critical path and/or in the open loop circuit.

    摘要: An integrated circuit for a modem processor includes processing units that are partitioned into “always-on” and “collapsible” power domains. An always-on power domain is powered on at all times. A collapsible power domain can be powered off if the processing units in the power domain are not needed. A power control unit within an always-on power domain powers down the collapsible power domains after going into sleep and powers up these domains after waking up from sleep. Tasks for powering down the collapsible power domains may include (1) saving pertinent hardware registers for these power domains, (2) freezing output pins of the IC to minimally disturb external units, (3) clamping input pins of the collapsed power domains, (4) powering down a main oscillator and disabling the oscillator clock, and so on. Complementary tasks are performed for powering up the collapsed power domains.

    摘要: A method for quantizing decision metrics (e.g., log likelihood ratios (LLRs)) for reduction of memory requirements in wireless communication is described. The method includes selecting a quantization algorithm. The quantization algorithm may be selected as a function of a characteristic of a decision metric representative of a transport block received over a communication channel, a characteristic of the transport block, or a condition of the communication channel. The method further includes quantizing the decision metric using the selected quantization algorithm to generate at least one quantized decision metric representative of the transport block. The method further includes storing the quantized decision metric and an indicia of the selected quantization algorithm to enable recovery of the decision metric representative of the transport block prior to decoding.

    摘要: A direct downconversion receiver architecture having a DC loop to remove DC offset from the signal components, a digital variable gain amplifier (DVGA) to provide a range of gains, an automatic gain control (AGC) loop to provide gain control for the DVGA and RF/analog circuitry, and a serial bus interface (SBI) unit to provide controls for the RF/analog circuitry via a serial bus. The DVGA may be advantageously designed and located as described herein. The operating mode of the VGA loop may be selected based on the operating mode of the DC loop, since these two loops interact with one another. The duration of time the DC loop is operated in an acquisition mode may be selected to be inversely proportional to the DC loop bandwidth in the acquisition mode. The controls for some or all of the RF/analog circuitry may be provided via the serial bus.
