Publication number: 20180032457Abstract: Slave initiated interrupts for a communication bus are disclosed. In one aspect, the communication bus is a radio frequency front end (RFFE) bus, and a slave is allowed to indicate to a master on the RFFE bus that the slave has an interrupt condition. On receipt of a slave initiated interrupt, the master may initiate a polling sequence to determine which of a plurality of slaves associated with the RFFE bus initiated the interrupt and process the interrupt accordingly. Continuing the exemplary aspect, the slave may indicate the interrupt condition to the master by driving a clock line of the RFFE bus to a non-idle state. The master may detect this manipulation of the clock line and initiate the polling sequence.Type: ApplicationFiled: July 26, 2016Publication date: February 1, 2018Inventors: Lalan Jee Mishra, Helena Deirdre O'Shea, Richard Dominic Wietfeldt

Publication number: 20170147521Abstract: Systems, methods, and apparatus for data communication are provided. An apparatus maybe configured to generate a mask field in a packet to be transmitted through an interface to a slave device, the mask field having a first number of bits, provide a control-bit field in the packet, the control-bit field having a second number of bits, where the second number of bits is less than the first number of bits, and transmit the packet through the interface. The packet may be addressed to a control register of the slave device. The control register may have the first number of bits. Each bit in the control-bit field may correspond to a bit of the control register that is identified by the mask field.Type: ApplicationFiled: November 8, 2016Publication date: May 25, 2017Inventors: Lalan Jee Mishra, Richard Wietfeldt, Helena Deirdre O'Shea

Publication number: 20170116141Abstract: Methods and apparatuses are described that facilitate the communication of data between a transmitter and a receiver across a serial bus interface. In one configuration, a transmitter generates a datagram based on a 16-bit address and a mask-and-data pair burst length, the 16-bit address including a most significant byte (MSB) and a least significant byte (LSB), compares the MSB to a receiver base address maintained in a shadow register, compares the mask-and-data pair burst length to a receiver masked-write burst length maintained in the shadow register, and sends the datagram to the receiver via the bus interface when: the MSB is equal to the receiver base address maintained in the shadow register, and the mask-and-data pair burst length is equal to the receiver masked-write burst length maintained in the shadow register.Type: ApplicationFiled: October 19, 2016Publication date: April 27, 2017Inventors: Lalan Jee Mishra, Richard Wietfeldt, Helena Deirdre O'Shea, Zhenqi Chen, Wolfgang Roethig

Publication number: 20170118125Abstract: Methods and apparatuses are described that facilitate the communication of data between a transmitter and a receiver across a serial bus interface. In one configuration, a transmitter generates a datagram based on a register address, detects whether the register address is within a high data rate (HDR) access address range, and sends a payload of the datagram to the receiver according to a HDR mode when the register address is within the HDR access address range. In another configuration, the transmitter generates a datagram including at least a command field and a data field, sends the command field to the receiver according to a single data rate (SDR) mode, wherein the command field indicates a transition to a high data rate (HDR) mode for sending the data field, and sends the data field to the receiver according to the HDR mode.Type: ApplicationFiled: October 19, 2016Publication date: April 27, 2017Inventors: Lalan Jee Mishra, Richard Wietfeldt, Helena Deirdre O'Shea, Zhenqi Chen, Wolfgang Roethig

The method can be implemented using dedicated logic and managed and controlled by state machines and/or sequencers. Data received or provided in a memory of a first integrated circuit of a terminal is encoded and transmitted in a data packet to a second integrated circuit. A header identifying the data type and providing a destination is included in the data packet. The destination may be identified as a memory address memory of the second integrated circuit that is mapped to a corresponding memory address of the first integrated circuit at which the data is received. In an aspect, the apparatus receives a header, detects an error in the received header, determines a failure to identify a packet boundary when the error is detected, and performs a search operation to identify the packet boundary.Type: GrantFiled: June 27, 2013Date of Patent: January 12, 2016Assignee: QUALCOMM IncorporatedInventors: Hans Georg Gruber, Subra Dravida, Parvathanathan Subrahmanya, Vidyut Mukund Naware, Helena Deirdre O'Shea, Garret Webster Shih, Jason Thurston

Patent number: 8964617Abstract: Access terminals are adapted to regulate power in wireless receiver circuits. In one example, access terminals include a communications interface with at least one wireless receiver circuit. A processing circuit coupled with the communications interface can receive a transmission during a Frequency Correction Channel (FCCH) frame. Following the received transmission, at least a portion of the receiver circuit may be powered down. A determination may also be made whether the received transmission was reliable. The receiver circuit can subsequently be powered up, and another transmission can be received on a subsequent channel. When the received transmission was sufficiently reliable, the other transmission may be a transmission during a Synchronization Channel (SCH) frame. When the received transmission is not sufficiently reliable, the other transmission may be another transmission received during a subsequent Frequency Correction Channel (FCCH) frame.Type: GrantFiled: January 11, 2013Date of Patent: February 24, 2015Assignee: QUALCOMM IncorporatedInventors: Divaydeep Sikri, Farrukh Rashid, Helena Deirdre O'Shea, Cetin Altan, Wolfram Pieperhoff

Patent number: 8254855Abstract: Techniques for identifying and suppressing frequency spurs in a signal are disclosed. In an embodiment, an incoming signal is rotated by a frequency related to a spur frequency, and an estimate of the content of the rotated signal is derived. The estimate may be subtracted from the rotated incoming signal, and the result de-rotated by the spur frequency. In an embodiment, the incoming signal may be rotated such that the spur is centered at DC. In an alternative embodiment, the estimate may be de-rotated before being subtracted from the original incoming signal. Techniques for addressing multiple spurs using serial and parallel architectures are disclosed. Further disclosed are techniques for searching for the presence of spurs in an incoming signal, and tracking spur frequencies over time.Type: GrantFiled: May 7, 2008Date of Patent: August 28, 2012Assignee: QUALCOMM, IncorporatedInventors: Daniel Fred Filipovic, Helena Deirdre O'Shea, Christos Komninakis, Jifeng Geng

Patent number: 7127663Abstract: A system and method for bad frame indication of a speech frame includes estimating a signal-to-noise ratio (SNR) and checking a cyclic redundancy code (CRC) value of the speech frame. When the speech frame fails CRC error detection or the SNR is below a pre-specified value, a bad frame indication (BFI) flag is set. When the speech frame passes CRC error detection and the SNR is above the pre-specified value, a receive signal quality metric of the speech frame is checked against a high threshold and, if need be, a low threshold. The BFI flag and the receive signal quality metric for the previous speech frame is checked when the current receive signal quality metric is between the high and low thresholds. The BFI flag is set according to the value of the SNR, the CRC value, the current and previous receive signal quality metrics, and the previous BFI flag.Type: GrantFiled: August 28, 2003Date of Patent: October 24, 2006Assignee: Qualcomm IncorporateInventors: Mohammad J.
