Description

technical field [0001] The invention belongs to the technical field of chip quality screening, and relates to video processing and chip aging technologies, in particular to a daisy chain-based video processing chip aging device and method. Background technique [0002] In the process of chip manufacturing and chip quality screening, it is necessary to conduct performance tests and sophisticated experiments on a large number of chips at the same time. in demanding fields. However, in the current process of chip aging, not only the workload of testing the chips one by one and screening the quality level is relatively large, but the efficiency is low, and it is difficult to meet the needs of real-time detection of the chip, and the flexibility of the chip aging device is limited, so it cannot be adapted to the Requirements for sophisticated experiments to be performed simultaneously with different numbers of chips. Contents of the invention [0003] In order to solve the pr...
