Deep neural networks(DNNs) have been widely applied in visual data analysis. To accelerate DNN-based visual data inference, contemporary visual data analytics systems employ strategies like model specialization and model cascading to alleviate the computational demands of DNN processes. In addition, some existing systems seek to reduce the overhead of data decoding by directly storing decoded RGB data on storage devices, albeit at the expense of significantly increased storage costs and data transfer volumes. In this paper, we introduce ISVDA, a visual data analysis accelerator based on In-storage computing. ISVDA proposes to offload the data-intensive video preprocessing tasks, encompassing data decoding and resizing, to the computational storage device, leveraging its ample internal bandwidth and computational advantages. Concurrently, ISVDA introduces a dynamic sampling algorithm that intelligently adjusts sampling strides based on spatiotemporal information encoded in motion vectors, thereby skipping more video frames for DNN inferences in both retrospective and streaming analysis scenarios. Experiments conducted on real hardware demonstrate that compared to CPU-based preprocessing systems, ISVDA can achieve average 6.8x speedup for image data analysis and 2.8x speedup for video data analysis.

Band-Stop filter is one of the key components in smart grids, wireless communications systems, radar, and signal processing. Due to the ability of suppressing signals at specific frequencies, these filters enable the rejection of unwanted signals in a particular frequency band in a crowded microwave spectra. Specifically, such filters can be utilized to mitigate the effect of harmonics in smart grids. The traditional band-stop filters suffer from lack of high suppression, reconfigurable bandwidth and frequency agility. This paper presents a novel approach to realize reconfigurable and flexible band-stop filters using the computing-in-memory (CIM) technique. The proposed scheme consists of a low-pass filter and a high-pass filter, with their corresponding coefficients programmed into an array of memristive devices. As a result, reconfigurable and low-complexity band-stop filters can be implemented, which support the realization of arbitrary filter impulse responses and high-order filters.
Scalable image coding for both humans and machines is a technique that has gained a lot of attention recently. This technology enables the hierarchical decoding of images for human vision and image recognition models....
