An ultrasound diagnosis apparatus includes a scanner, an input unit, a change unit, a prediction unit, a processor, and a second processor. In one example, high-speed microelectronic devices based on coplanar stripline implementations support differential signals in a range of approximately from 1 Gigahertz to at least 60 Gigahertz. The one or more tracks are written to a selected stride of the plurality of strides, based on comparing the number of operations required to destage selected tracks from the selected stride to the number of operations required to defragment the compressed data in the selected stride. Processes are disclosed for retrieving and loading configuration code in pre-boot and runtime environments. The method includes the steps of: receiving a scroll signal from an input device for scrolling an image on the monitor screen, checking a current condition of the navigation system related to the scroll operation, and conducting the scroll operation while adjusting the scroll speed and scale factor of the image based on the current condition. The mapping of sets to streams is permuted in time.
