The embodiment of the invention discloses a storage-calculation integrated circuit and a data operation method based on the storage-calculation integrated circuit, which relate to the technical field of memory. The storage and calculation integrated circuit includes: a configuration unit, used to calculate the maximum value of the number of storage units in one addition operation within a preset precision error range; a gating unit, used to Provide a strobe signal; a storage and calculation unit, according to the strobe signal, block the memory array by row and column to obtain at least one sub-block, and the storage and calculation unit is used to strobe each time according to the strobe signal One of the sub-blocks is used to perform multiplication and addition operations on the data to be operated and the storage data of the storage array in blocks; an analog-to-digital conversion unit is used to convert the analog operation results of each of the sub-blocks into digital operation results ; an accumulation and summation unit, performing an addition operation on the digital operation result of the at least one sub-block to obtain the multiplication-add operation result of the storage-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...
