Kompresia údajov MRI pomocou 3-D diskrétnej vlnkovej transformácie

Je opísaný nízkoenergetický systém, ktorý možno použiť na kompresiu údajov MRI a na iné lekárske aplikácie. The system uses a low power 3-D DWT processor based on a centralized control unit architecture. The simulation results show the efficiency of the wavelet processor. The prototype processor consumes 0.5 W with total delay of 91.65 ns. The processor operates at a maximum frequency of 272 MHz. The prototype processor uses 16-bit adder, 16-bit Booth multiplier, a 1 kB cache with a maximum of 64-bit data bandwidth. Lower power has been achieved by using low-power building blocks and the minimal number of computational units with high throughput.
