Patent number: 7043520Abstract: A partial carry-save format is employed for a finite impulse response filter output representation, thereby reducing a number of flip-flops and hence power. By replacing the least significant bit processing section on the output side of the finite impulse response filter with a combined carry-save adder and carry-propagate adder followed by a register rather than two flip-flops, the present invention reduces the load on the clock and achieves reduced propagation delay. To further improve the performance of the finite impulse response filter, a simpler carry-save adder is employed in the least significant bit section, which is possible due to the use of a single register at an input to each of the carry-save adders rather than two flip-flops, one for a carry output and one for a sum output from the adder.Type: GrantFiled: November 29, 2003Date of Patent: May 9, 2006Assignee: Agere Systems Inc.Inventors: Patrik Larsson, Christopher John Nicol

Patent number: 6898281Abstract: A system and method for echo and near end cross talk (E/N) cancellation in a communications system using a pair of FIR filter ICs, wherein a first FIR filter IC filters a plurality of low amplitude E/N signals and a first portion of a plurality of data bits of a plurality of high amplitude E/N signals, and a second FIR filter IC filters a second portion of the data bits of the high amplitude E/N signals which cannot be filtered by the first FIR filter IC. The output values from the two filters are then summed to produce the E/N cancellation signal. The present invention allows for the use of lower bit-resolution, lower power consumption, and less expensive filter ICs than conventional FIR filters implemented in a single IC.Type: GrantFiled: January 5, 2000Date of Patent: May 24, 2005Assignee: Lucent Technologies Inc.Inventors: Patrik Larsson, Christopher John Nicol

Patent number: 6785327Abstract: Multiported register files used for storing coefficients in adaptive FIR are improved upon by implementing a split memory architecture that has the ability to separately control the least significant bits and the most significant bits of coefficient values that are stored in the filter. When the filter is operated to use so-called “burst mode” updating, the updating circuitry of the filter can be disabled and only the most significant bits of the coefficients are read out from the multiported register file while the least significant bits remain unchanged. This conserves power without sacrificing precision, since only certain ones of the bits of the coefficients are used in the multiplication of the sample.Type: GrantFiled: December 23, 1997Date of Patent: August 31, 2004Assignee: Agere Systems, Inc.Inventors: Patrik Larsson, Christopher John Nicol

Patent number: 6542539Abstract: Multiported register files for use in storing coefficients in adaptive FIR filters. incorporate computational ability, e.g., the ability to perform computation on coefficient values or derivatives thereof, or to control the operations performed thereon. For example, a multiported register file may incorporate an overflow/underflow detection and/or saturation unit. Also, the multiported register file may incorporate a special encoder to speed up the multiplication process, e.g., the so-called “Booth” encoder. Likewise, the multiported register file may incorporate a converter for changing the representation of the coefficients, e.g., a two's complement to sign-magnitude converter. All computation performed in the multiported register file is performed outside of the critical path of the filtering or of the coefficient updating. Using such improved multiported register files, adaptive FIR filters can be constructed which operate faster, and with lower power consumption.Type: GrantFiled: December 23, 1997Date of Patent: April 1, 2003Assignee: Agere Systems Guardian Corp.Inventors: Patrik Larsson, Christopher John Nicol

Patent number: 6377619Abstract: Multiported register files are employed to implement the input delays necessary for finite impulse response (FIR) filter operation. A multiported register file is a memory, typically small, with at least one read port and one write port. Data written into the multiported register file may be read out therefrom in any desired order. The multiported register tile may have additional output ports from which the data stored therein may be read out, also in any desired order, and independent from the order of any other output port. At least one output of each multiported register file is coupled to the input of the next stage of the FIR filter, if any. In addition, each multiported register file feeds data from one output to the multiply-add portion of its associated stage of the FIR filter.Type: GrantFiled: September 26, 1997Date of Patent: April 23, 2002Assignee: Agere Systems Guardian Corp.Inventors: Tracy C. Denk, Patrik Larsson, Christopher John Nicol

Patent number: 6344772Abstract: A capacitance multiplier network embodying the invention includes a first resistor, R1, connected between a first node and an intermediate node and a first capacitor, C1, connected between the intermediate node and a point of reference potential. A unity gain amplifier has an input connected to the intermediate node and its output is connected via a second resistor, R2, to the first node. The unity gain amplifier ensures that the voltage drop across the second resistor is equal to the voltage drop across the first resistor. The effective capacitance, Ce, of the network is equal to C1 times [R1+R2]/R2. Thus, by making R1 larger than R2, Ce is much large than the capacitance of C1. The capacitance multiplier network is well suited for use in phase locked loop circuits and enables the integration of a very dense circuit on the same IC chip.Type: GrantFiled: June 6, 2000Date of Patent: February 5, 2002Assignee: Agere Systems Guardian CorpInventor: Patrik Larsson
