Digital memory arrays, which serve as an integral part of modern computing systems, are traditionally used for information storage. However, recent reports show that memory can be used on demand as a reconfigurable computing resource, drastically improving energy efficiency for many applications. In this case, memory usage is limited to storing function responses as multi-input multi-output lookup...
We have proposed a novel center-of-gravity (COG) time-over-threshold (TOT) method for PET detectors readout. In order to reduce the output channels it uses the charge division architecture and all the detector signals will be read out and multiplexed into 3 TOT outputs. The COG position can be decoded from the TOT information only without causing too much distortion. This method has very simple structure...
XOR based RAID 6 systems outperform other RAID systems. Among the XOR (exclusive OR) based RAID-6 schemes, RDP has better performance than others by a narrow margin. However, the RDP code scheme cannot take full advantage of parallel hardware implementation of XOR codes. In this paper, we propose an extension of the double-erasure-correcting RDP code called EDP, which consists of a parallel decoding...
In recent years, researchers have found that some XOR erasure codes lead to higher performance and better throughput in fault-tolerant distributed data storage applications. However, little consideration has been given to the advantages of parallel processing or hardware implementations taking advantage of the emergence of multi-core processors. This paper presents an efficient horizontal MDS-like...
