1. 1. Tribonacci Cat Map : A discrete chaotic mapping with Tribonacci matrix

   Master-uppsats, Linnéuniversitetet/Institutionen för matematik (MA)

   Författare :Linnea Fransson; [2021]
   Nyckelord :Arnold s cat map; Tribonacci matrix; chaotic map; discrete dynamical system; linear recurrence sequence; Trisano period; 3D image encryption; colour encryption;

   Sammanfattning : Based on the generating matrix to the Tribonacci sequence, the Tribonacci cat map is a discrete chaotic dynamical system, similar to Arnold's discrete cat map, but on three dimensional space. In this thesis, this new mapping is introduced and the properties of its matrix are presented. LÄS MER

3. 2. Speeding up matrix computation kernels by sharing vector coprocessor among multiple cores on chip

   Master-uppsats, JTH, Data- och elektroteknik

   Författare :Christopher Dahlberg; [2012]
   Nyckelord :Coprocessor; Speeding-up; Accelerator; Power efficiency; Shared resources; Vector processor; Multi-core on chip; Matrix algorithm; Matrix computation kernels;

   Sammanfattning : Today’s computer systems develop towards less energy consumption while keeping high performance. These are contradictory requirement and pose a great challenge. A good example of an application were this is used is the smartphone. The constraints are on long battery time while getting high performance required by future 2D/3D applications. LÄS MER
