    Abstract: The present disclosure proposes a method used by a receiver for facilitating de-rate matching of bits of symbols formed after a rate matching procedure from a transmitter, wherein the transmitter selected Z bits from channel-coded bits, and then generated E bits by concatenation of the Z bits and their copies for the rate matching procedure. The method comprises: demodulating the symbols to obtain E soft bits corresponding to the E bits; zeroing values at Z consecutive locations of a memory, wherein the Z consecutive locations correspond to bit positions of the Z bits; writing the E soft bits into a buffer device; for each soft bit of the E soft bits in the buffer device, directly adding value of the soft bit and value from a location of the Z consecutive locations and storing result of the addition back into the location, wherein a bit in the E bits corresponding to the soft bit is a bit in the Z bits corresponding to the location or a copy of the bit in the Z bits; and restoring the Z bits from the final results at the Z consecutive locations. The method facilitates the de-rate matching by reducing its memory usage and processing latency.

    Abstract: A storage device may determine a target data segment from among a plurality of data segments, execute a hash function on the target data segment, and cache the target data segment in a data segment cache based on a result of executing the hash function on the target data segment. The data segment cache may be a hash table including N buckets each of which is able to cache one or more data segments. The hash function may be a function which outputs an index of the target bucket based on N, an index of the target data segment, and a seed value.

    Abstract: Disclosed is an improved approach to implement caching. An adaptive and performance aware caching framework is provided that complements the existing state-of-the-art caching algorithms. Instead of using fixed-sized cache unit sizes, the approach adaptively switches to a cache unit size that incurs the lowest performance penalty, thereby yielding faster I/O and improved system performance.
