| abstract
(eng) |
The paper describes in detail an FPGA implementation of the QR update algorithm with Givens rotations using the High Speed Logarithmic Arithmetic (HSLA) library. This library is based on integer computations with logarithmic equivalents of the floating-point numbers. An important advantage of this approach is low latency and accurate computation (comparable with single-precision floating point) of the operations. |

Článek přináší detailní popis FPGA implementace algoritmu pro QR aktualizaci pomocí Givensových rotací s použitím knihovny High Speed Logarithmic Arithmetic (HSLA). Tato knihovna využívá celočíselných výpočtů na logaritmých ekvivalentech čísel v plovoucí řádové čárce. Výhodou tohoto přístupu je malá latence výpočtů a přesnost aritmetických operací (srovnatelná s výpočty v plovoucí řádové čárce s jednoduchou přesností) |
