Abstract

The embodiment of the invention discloses a storage space management method, which comprises the following steps of: responding to an address application request from a first data processing module in a plurality of data processing modules, and based on an address of a discontinuous spare physical storage space of an on-chip memory; an address mapping relation between the unoccupied physical storage space and a section of continuous virtual space is established, and addresses of the continuous virtual space are sent to the first data processing module; in response to an access request of the first data processing module for the address of the continuous virtual space, determining a physical address corresponding to the address of the continuous virtual space based on the address mapping relationship; and accessing the on-chip memory based on the physical address to read or write data of the first data processing module. The embodiment of the invention further discloses a data processing chip, electronic equipment and a storage medium.

Description

technical field

[0001] The present application relates to the technical field of communications, and in particular to a storage space management method, a data processing chip, electronic equipment and a storage medium. Background technique

[0002] With the development of artificial intelligence technology, general-purpose artificial intelligence processors such as general-purpose neural network processors (Neural-network Processing Unit, NPU), in order to perform superposition processing on multiple different algorithms in a single scene, refer to figure 1 As shown, the internal architecture of the designed general-purpose NPU includes multiple data processing engines, such as NPU and digital signal processing (Digital signal processing, DSP), so that different algorithms after disassembly are mapped to different data processing engines for processing. Here, for the internal architecture of the general-purpose NPU, an on-chip memory (on chip memory, OCM) is plugged into th...
