Abstract
Data arrangement schemes of imagery data and filter coefficients stored in a CNN based digital IC for extracting features out of an input image are disclosed. The CNN based digital IC contains NE number of CNN processing engines connected in a loop via a clock-skew circuit for cyclic data access. Imagery data and filter coefficients are arranged in a specific scheme to fit the data access pattern that the CNN based digital IC requires to operate. The specific scheme is determined based on the number of imagery data, the number of filters and the characteristics of the CNN based digital IC. The characteristics include, but are not limited to, the number of CNN processing engines, the connection direction of clock-skew circuit and the number of the I/O data bus.
