  1. 1. Effects of Varying Precision on a FPGA using the SpMXV problem : A comparative study

    Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Vendela Asplund; Martin Lindefors; [2023]
    Nyckelord :;

    Sammanfattning : With Moore’s Law slowing down, designing computer hardware that keeps up with the performance demands is becoming increasingly difficult. An interesting area of research is the Field Programmable Gate Array (FPGA) which is a re-programmable hardware device, and which might not be as dependent on Moore’s Law as other hardware. LÄS MER

  3. 2. 64-point FFT Instruction Implementation and Evaluation on a Microcode Programmable Processor

    Master-uppsats, Linköpings universitet/Institutionen för systemteknik; Linköpings universitet/Tekniska fakulteten

    Författare :Yongjun Liu; Zejun Huang; [2022]
    Nyckelord :FFT; Instruction design;

    Sammanfattning : Fast Fourier Transform is an efficient algorithm for computing the Discrete Fourier Transform (DFT) and one of the most important algorithms used in many digital signal processing applications over decades. This thesis presents an efficient implementation method of a 32-bit complex number 64-point FFT instruction on a micro-programmable processor. LÄS MER

  4. 3. Assessing Differences in Precision with Posit Floating Point Format compared to IEEE 754

    Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Timmy Lindholm; Olof Jonnerby; [2021]
    Nyckelord :;

    Sammanfattning : Choosing the correct floating point representation can greatly impact the performance and precision of floating point operations. The current floating point representation standard is IEEE 754. A recent floating point representation which seems to yield a greater precision for the same number of bits is called Posit. LÄS MER

  5. 4. Mitchell-Based Approximate Operations on Floating-Point Numbers

    Master-uppsats, Linköpings universitet/Datorteknik

    Författare :Noah Hellman; [2021]
    Nyckelord :floating-point numbers; approximations; arithmetics; asic; fpga; mitchell;

    Sammanfattning : By adapting Mitchell's algorithm for floating-point numbers, one can efficiently perform arithmetic floating-point operations in an approximate logarithmic domain in order to perform approximate computations of functions such as multiplication, division, square root and others. This work examines how this algorithm can be improved in terms of accuracy and hardware complexity by applying a set of various methods that are parametrized and offer a large design space. LÄS MER

  7. 5. A Comparative Study on the Accuracy of IEEE-754 and Posit for N-body Simulations

    Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Christofer Nolander; Amanda Strömdahl; [2021]
    Nyckelord :;

    Sammanfattning : IEEE-754 has been the standard floating-point format for several decades. However, in recent years multiple new floating-point formats have emerged, one of which is Posit. This study aimed to examine the accuracy of 32-bit IEEE-754 compared to that of 32-bit Posit. LÄS MER
