Abstract

The invention provides a method and a device for detecting the bandwidth of an off-chip memory. Access frequency, operation time and data bandwidth of a memory controller are detected by a processor core to obtain the access real-time bandwidth of the off-chip memory. The processor core is connected with the memory controller through a signal by a system bus, and the off-chip memory is accessed by the memory controller, namely, all access of the off-chip memory is initiated by the memory controller, so that the access real-time bandwidth of the off-chip memory can be obtained by detecting the access frequency, the operation time and the data bandwidth of the memory controller through the processor core. In addition, detecting data can be conveniently obtained by the system bus as the system bus is arranged between the processor core and the memory controller, so that the access real-time bandwidth of the off-chip memory can be quite conveniently obtained.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a method and device for detecting the bandwidth of an off-chip memory. Background technique [0002] A system on chip (System On Chip, SOC) that integrates multiple processor cores into a single integrated circuit chip appears in a mobile terminal. A larger number of processor cores can allow more processing capabilities of integrated circuit chips. For example, rich multimedia applications can be realized while completing wireless communication data processing. High access bandwidth requirements. [0003] Therefore, it is very important to obtain the bandwidth information of the off-chip memory. In particular, obtaining the real-time bandwidth of off-chip memory access can help to control the multi-core processor and improve the operating efficiency of the system on chip. [0004] Please refer to figure 1 , which is a structural schematic diagram of an existing p...
