The embodiment of the invention discloses a storage and calculation integrated circuit, and a data operation method based on the storage and calculation integrated circuit, and relates to the technical field of memories. The storage and calculation integrated circuit comprises: a configuration unit used for calculating the maximum value of the number of the storage units in one-time additive operation within a preset precision error range; a gating unit used for providing a gating signal according to the maximum value; a storage unit used for partitioning the storage array into at least one sub-block in rows and columns according to the gating signal, wherein the storage unit is used for gating one sub-block every time according to the gating signal so as to carry out multiply-add operation on to-be-operated data and the storage data of the storage array in a partitioning manner; an analog-to-digital conversion unit used for performing analog-to-digital conversion on the analog operation result of each sub-block to obtain a digital operation result; and an accumulation summation unit used for carrying out addition operation on the digital operation result of the at least one sub-block to obtain a multiplication and addition operation result of the storage and calculation integrated circuit.
Description
technical field [0001] The invention relates to the technical field of memory, in particular to a storage-calculation integrated circuit and a data calculation method based on the storage-calculation integrated circuit. Background technique [0002] In the traditional von Neumann computing architecture, the memory and the processor are separated, and the two are connected through a data bus, and data processing needs to be transmitted back and forth between the memory and the processor. However, with the rise of big data applications, the transmission and processing of massive data makes the traditional von Neumann computing architecture face the dual challenges of bandwidth and power consumption, which are called storage wall and power consumption wall respectively. In order to solve these two problems, in recent years, inspired by the simultaneous memory and calculation of synapses in the human brain, the Processing-In-Memory (PIM) technology in computer architecture has b...
