  1. 1. An Energy-efficient 32-bit multiplier architecture in 90nm CMOS

    Uppsats för yrkesexamina på grundnivå, Institutionen för systemteknik

    Författare :Nasir Mehmood; [2006]
    Nyckelord :Modified Booth-encoding; carry save adder; multiplier; partial products; CMOS power; VLSI; SOC; Cadence;

    Sammanfattning : A fast and energy-efficient multiplier is always needed in electronics industry especially DSP, image processing and arithmetic units in microprocessors. Multiplier is such an important element which contributes substantially to the total power consumption of the system. LÄS MER

  3. 2. Implementation and evaluation of a polynomial-based division algorithm

    Uppsats för yrkesexamina på grundnivå, Institutionen för systemteknik

    Författare :Stefan Pettersson; [2003]
    Nyckelord :Electronics; Division; Algorithm; Polynomial; Newton-Raphson; Carry-save; Wallace tree; Elektronik;

    Sammanfattning : In comparison to other basic arithmetic operations, such as addition, subtraction and multiplication,division is far more complex and expensive. Many division algorithms, except for lookup tables, rely on recursion with usually complex operations in the loop. LÄS MER

  4. 3. Implementation of Pipelined Bit-parallel Adders

    Uppsats för yrkesexamina på grundnivå, Institutionen för systemteknik

    Författare :Lan Wei; [2003]
    Nyckelord :Electronics; Adder; Ripple carry adder; Carry look-ahead adder; Carry select adder; Carry save adder; Pipelining; Power consumption; Elektronik;

    Sammanfattning : Bit-parallel addition can be performed using a number of adder structures with different area and latency. However, the power consumption of different adder structures is not well studied. Further, the effect of pipelining adders to increase the throughput is not well studied. LÄS MER

  5. 4. Implementation and Evaluation of Single Filter Frequency Masking Narrow-Band High-Speed Recursive Digital Filters

    Uppsats för yrkesexamina på grundnivå, Institutionen för systemteknik

    Författare :Mikael Mohsén; [2003]
    Nyckelord :Electronics; digital filters; frequency masking; high-speed; low-power; voltage scaling; carry-save; Elektronik;

    Sammanfattning : In this thesis two versions of a single filter frequency masking narrow-band high-speed recursive digital filter structure, proposed in [1], have been implemented and evaluated considering the maximal clock frequency, the maximal sample frequency and the power consumption. The structures were compared to a conventional filter structure, that was also implemented. LÄS MER
