摘要： A bad page management system is provided to guarantee a yield of a volatile semiconductor memory device such as a DRAM. A bad page list exists in a DRAM. A page remapper in a memory controller performs a page remapping operation in parallel with a normal operation of a scheduling unit to perform a latency overhead hidden function. A chip size of the DRAM is reduced or minimized. A DRAM controller performs a latency overhead hidden function to control a DRAM.

摘要： A memory system includes a high-bandwidth memory device, the high-bandwidth memory device having a relatively high operation bandwidth, the high-bandwidth memory device having a plurality of access channels. A low-bandwidth memory device has a relatively low operation bandwidth relative to the high-bandwidth memory device, the low-bandwidth memory device having one or more access channels. An interleaving unit performs a memory interleave operation among the plurality of access channels of the high-bandwidth memory device and an access channel of the one or more access channels of the low-bandwidth memory device.

摘要： Provided is a method for converting a first image signal expressed in a first color space into a second image signal expressed in a second color space on a subword parallelism basis. The method includes determining a first image parameter of a second image signal matrix as a function calculated by multiplying conversion coefficients of a first row constituting an image conversion matrix by image parameters constituting a first image signal matrix; determining a second image parameter of the second image signal matrix as a function expressed by at least one of image parameters constituting the first image signal matrix and the determined first image parameter of the second image signal matrix; determining a third image parameter of the second image signal matrix as a function expressed by at least one image parameter unused for determining the second image parameter of the second image signal matrix among the image parameters constituting the first image signal matrix, and by the determined first image parameter of the second image signal matrix; and finally calculating the second image signal matrix by shifting the determined image parameters constituting the second image signal matrix by a predetermined number of bits.

摘要： Disclosed is a parallel processing method in a data processing system that temporarily loads data stored in a memory in word registers and parallel-processes subwords constituting the loaded word using Arithmetic Logic Units (ALUs) which are equal in size to the subwords. The method includes generating a shortened subword by removing at least one bit among the bits constituting each subword; and performing parallel computation on the shortened subwords.
