A semiconductor device includes a system-on-chip (SOC) and at least one wide input/output memory device. The SOC includes a plurality of SOC bump groups which provide input/output channels, respectively, independent from each other. The at least one wide input/output memory device is stacked on the system-on-chip to transmit/receive data to/from the system-on-chip through the SOC bump groups. The SOC bump groups are arranged and the at least one wide input/output memory device is configured such that one of the wide input/output memory devices can be mounted to the SOC as connected to all of the SOC bump groups, or such that two wide input/output memory devices can be mounted to the SOC with each of the wide input/out memory devices connected a respective half of the SOC bump groups.

Semiconductor device and semiconductor package

A video decoder organizes and stores pixel lines of a reference picture into first and second memory devices. The video decoder then reads portions of a pixel block from the first and second memory devices and processes such a pixel block for generating a subsequent picture. By reading from the first and second memory device with time overlap, latency is minimized for faster video decoding.

Method and apparatus for decoding video data

In the scanning conversion apparatus, interlaced-to-progressive scanning is performed according to one of at least two different techniques. The technique used depends on the interlaced scan data being converted. As examples, a spatial interpolation technique, a spatial/temporal interpolation technique, or other technique may be selected.

Scanning conversion apparatus and method

In the scanning conversion apparatus, a first converter converts input interlaced scan data into progressive scan data, and a second converter converting the progressive scan data output from the first converter to interlaced scan data.

A stereophonic image may be enhanced by splitting the left and right input audio signals into a plurality of left and right output signals in a plurality of audio frequency bands and then generating left and right output audio signals from the left and right output signals based on the magnitude of the differences between corresponding left and right output signals and also based upon the absolute magnitude of the left and right input audio signals themselves. In particular, a stereophonic image enhancement device according to the invention processes a left input signal and a right input signal using a first spectrum analyzer and a second spectrum analyzer which output a plurality of left output signals and right output signals corresponding to a plurality of frequency bands in response to the corresponding left input signal and right input signal. A table lookup signal is responsive to the plurality of left output signals and to the plurality of right output signals to output a plurality of left output signal pairs and a plurality of right output signal pairs. A first and second adder are responsive to the plurality of left output signal pairs and right output signal pairs respectively to add the output signal pairs and produce final left output signals and right output signals respectively.
