Data storage control method and apparatus for external storage device using a plurality of flash memories

The present invention is to realize a data storage control method and apparatus for an external storage device using flash memories. The method and apparatus can eliminate the data erasure waiting time, eliminating the calculation of the erasure numbers of flash memories, elongating the life-time of the flash memories. Data is stored sequentially from a first flash memory for rewrite data to a third flash memory for rewrite data. When there is no vacant area in the third flash memory for rewrite data, a CPU instructs a first flash memory for garbage collection among the first and second flash memories for garbage collection to perform the garbage collection of the first flash memory for rewrite data. When a host computer issues a write access request, the write process is performed in the first flash memory for garbage collection with the first priority. When the garbage collection of the first flash memory for rewrite data has been completed, the garbage collection of the second flash memory for rewrite data is performed by the second flash memory for garbage collection. At the time of performing the garbage collection of the second flash memory for rewrite data, the data of the first flash memory for rewrite data is simultaneously erased. The first flash memory for garbage collection is changed into a flash memory for rewrite data by the CPU. Upon completion of the garbage collection of the second flash memory for rewrite data, the data thereof is simultaneously erased and the second flash memory for garbage collection is changed into a flash memory for rewrite data. Then, the garbage collection of the third flash memory for rewrite data is performed in the similar manner.

Reduced parallel and pipelined high-order MIMO LMMSE receiver architecture

Disclosed is a LMMSE receiver that restores orthogonality of spreading codes in the downlink channel for a spread spectrum signal received over N receive antennas. The FFT-based chip equalizer tap solver reduces the direct matrix inverse of the prior art to the inverse of some submatrices of size N×N with the dimension of the receive antennas, and most efficiently reduces matrix inverses to no larger than 2×2. Complexity is further reduced over a conventional Fast Fourier Transform approach by Hermitian optimization to the inverse of submatrices and tree pruning. For a receiver with N=4 or N=2 with double oversampling, the resulting 4×4 matrices are partitioned into 2×2 block sub-matrices, inverted, and rebuilt into a 4×4 matrix. Common computations are found and repeated computations are eliminated to improve efficiency. Generic design architecture is derived from the special design blocks to eliminate redundancies in complex operations. Optimally, the architecture is parallel and pipelined.
