The invention provides a convolution operation chip and communication equipment. The convolution operation chip comprises an M*N multiplier accumulator array, a data cache module and an output control module; the M*N multiplier accumulator array comprises a first multiplier accumulator window, and a processing unit PE<X, Y> of the first multiplier accumulator window is used for conducting multiplication operation on convolution data of the PE<X, Y> and convolution parameters of the PE<X, Y> and transmitting the convolution parameters of the PE<X, Y> to PE<X, Y+1> and transmitting the convolution data of the PE<X, Y> to PE<X-1, Y+1> to serve as multipliers of multiplication operation between the PE<X, Y+1> and the PE<X-1, Y+1>; the data cache module is used for transmitting the convolution data and the convolution parameters to the first multiplier accumulator window; the output control module is used for outputting a convolution result. According to the convolution operation chip and the communication equipment, the RAM access frequency can be decreased and the RAM access stress can be relieved while the array resource utilization rate is increased.
