Dynamic reconfigurable memory address mapping method and device

Abstract

A dynamically reconfigurable memory address mapping method and device provided by the present invention relates to chip technology, by obtaining the configuration parameters of the chip and the memory concurrent access mode of the target application, and generating an address based on the configuration parameters and the memory concurrent access mode The memory address mapping relationship of the target application; receiving a user execution request for the target application, and invoking the memory address mapping relationship corresponding to the target application according to the execution request; dynamically configuring the memory address mapping relationship according to the memory address mapping relationship The technical solution of the memory subsystem of the chip, when executing the target application, dynamically configures the memory subsystem of the chip according to the memory address mapping relationship. This solution can be combined with a specific target application to generate a corresponding memory address mapping relationship to adapt to artificial There are more complex memory access patterns in application scenarios such as intelligent and high-performance computing.

Description

technical field [0001] The invention relates to chip technology, in particular to a dynamically reconfigurable memory address mapping method and device. Background technique [0002] High-throughput computing chips such as GPUs and AI chips require the support of high-bandwidth memory subsystems. Existing memory systems have extremely high theoretical bandwidth. However, the actual applications running on the chip are subject to the resource competition of the memory subsystem and the competition among concurrent computing units. It is difficult to achieve the nominal theoretical bandwidth of the memory system, and additional power consumption may be caused by improper use of resources. [0003] In the prior art, in order to solve resource competition, memory address remapping is used to distribute concurrent memory access requests to memory resources that can process multiple memory requests in parallel. [0004] However, in the existing technology, the memory access mode...

Problems solved by technology

[0004] However, in the existing technology, the memory access modes of applications running on high-throughput computing chips such as GPU and AI are complex and changeable, and the parameters of the memory subsystem will also change with different chip configurations (such as virtualization). Meet the needs of all scenarios with a single address mapping function
