Abstract: The technology relates to allowing a user to enter text into text boxes using a stylus. For instance, first user input identifying a text box displayed on a display of the computing device may be received. Based on the received first user input, a handwriting field may be generated on the display without visual impact on the display. A second user input within the handwriting field may be received. The second user input may be converted into typed text, and the typed text may be displayed in the text box.

Abstract: The invention relates to a multitask processing system including a data bus and a command bus. Each one of a plurality of operators is provided to perform a processing determined by an instruction and is likely to issue a command request in order to receive an instruction from the command bus and to issue a transfer request on response to an acknowledgment of the command request, in order to receive or provide data being processed, through the data bus. A memory controller arbitrates the transfer requests and manages the data transfers on the data bus between the operators and a memory. A sequencer arbitrates the command requests, determines instructions to provide the operators with, and manages the instruction transfer through the command bus.
