Abstract: The present disclosure relates to a wide-angle lens assembly, which comprises, sequentially along an optical axis from an object side to an image side: a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens, a seventh lens, an eighth lens, a ninth lens and a tenth lens. The first lens, the second lens, the third lens, the fifth lens and the ninth lens each has a negative refractive power; the fourth lens, the sixth lens and the tenth lens each has a positive refractive power; and a refractive power of the seventh lens and a refractive power of the eighth lens are positive-negative opposite.

Abstract: The present application provides an on-chip cache apparatus, an on-chip cache on-chip cache read-write method and a computer-readable medium, the on-chip cache apparatus includes: a read-write processing module, a cache module and a memory module; the read-write processing module is connected with the cache module and the memory module respectively, and is configured to store packets into the cache module and the memory module, read packets stored in the cache module and the memory module, and transfer packets cached in the cache module to the memory module for storing; the cache module is connected with the memory module through the read-write processing module, and includes at least one cache register configured to temporarily cache packets; and the memory module is connected with the read-write processing module, and is configured to store the packets cached in the cache module.
