摘要： A method for managing an image memory in an embedded device is provided. A node is obtained from a linked list of the image memory. It is judged whether valid data is present in a memory block corresponding to the node. When no valid data is present, it is judged whether valid data is present in a memory block corresponding to a previous node of the node. When valid data is present in the previous node, it is further judged whether the valid data is movable. When the valid data is movable, memory block information described in the two nodes is exchanged, and the valid data previously stored in the memory block corresponding to the previous node is moved to the memory block corresponding to the node.

摘要： A variable-gain low-noise amplifier (VG-LNA) accepts a single-ended input signal at an input port and provides a differential output signal at an output port. The VG-LNA includes amplifier stages that are commonly coupled to the input port, with subtrahend amplifier stages commonly coupled to a negative terminal of the output port and minuend amplifier stages commonly coupled to a positive terminal of the output port. A control circuit activates up to one of the subtrahend amplifier stages and one of the minuend amplifier stages as a differential set of amplifier stages that generates the differential output signal from the single-ended input signal.
