TIME-CONSTRAINED DATA COPYING BETWEEN STORAGE MEDIA

摘要

Time-constrained data copying between storage media is disclosed. When an electronic device is engaged in real-time operations, multiple data blocks may need to be copied from one storage medium to another storage medium within certain time constraints. In this regard, a data port is operatively controlled by a plurality of registers of a first register bank. The plurality of registers is copied from the first register bank to a second register bank within a temporal limit and while the data port remains under control of the plurality of registers being copied. By copying the plurality of registers within the temporal limit, it is possible to prevent operational interruption in the data port and reduce bandwidth overhead associated with the register copying operation.

主权项

1. A data port, comprising:
a first register bank comprising a plurality of first registers, the first register bank configured to function as an active register bank to control a present operation of a data port; a second register bank comprising a plurality of second registers, the second register bank configured to function as a passive register bank to control a future operation of the data port; and a control logic coupled to the first register bank and the second register bank, the control logic configured to copy the plurality of first registers of the first register bank to the plurality of second registers of the second register bank within a temporal limit and without interrupting the present operation of the data port.
