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

    Författare :David Mallasén Quintana; [2022]
    Nyckelord :Computer Arithmetic; Conjugate Gradient; Posit; IEEE-754; Floating Point; High-Performance Computing; RISC-V; Datoraritmetik; Konjugerad Gradient; Posit; IEEE-754; Flytande Punkt; Högpresterande Beräkningar; RISC-V;

    Sammanfattning : Emerging floating-point arithmetics provide a way to optimize the execution of computationally-intensive algorithms. This is the case with scientific computational kernels such as the Conjugate Gradient (CG) linear solver. Exploring new arithmetics is of paramount importance to maximize the accuracy and timing performance of these algorithms. LÄS MER

  3. 2. 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

  4. 3. 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

  5. 4. An evaluation of a new standard for floating point precision : A quantitative comparison of Posit and IEEE 754 Float

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

    Författare :William Nilsson; Jakob Arvidsson; [2021]
    Nyckelord :;

    Sammanfattning : Posit is a new floating point precision representation that has been developed as an alternative to the existing IEEE 754 floating point standard. Prior studies have found several use-cases for posit, but also potential drawbacks. LÄS MER

  7. 5. An error assessment of matrix multiplications on posit matrices

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

    Författare :August Danell Håkansson; Mirja Johnsson; [2020]
    Nyckelord :Posit; softPosit Library; Moore’s Law; Posit; softPosit; Moores Lag;

    Sammanfattning : The posit is a floating-point number format as proposed by John Gustafson to improve upon the accuracy of the IEEE-754 format, which is the standard today. The goal of this paper was to look specifically at matrix multiplication and examine how the posit format compared to the IEEE-754. LÄS MER
