Abstract

A frequency adaptive high-speed storage system, including: multiple slave device interfaces, used to send access requests to the control unit, and receive response information and data from the control unit; the control unit, used to arbitrate and process access requests, will prioritize Send the highest-level request to the memory and suspend the low-priority request to monitor the conflict situation of the memory port access in real time; the frequency ratio adjustment unit is used to obtain the storage system clock by frequency division of the external input clock of the memory system according to the conflict situation, and at the same time Generate a clock synchronization signal; the synchronization unit is used to convert the access request sent by the master device into an access request signal in the clock domain of the storage system according to the clock synchronization signal, and convert the data or response information returned by the storage system into a signal in the clock domain of the master device . The invention can automatically adjust the memory access frequency according to the system's requirement on the bandwidth of the storage system, so that it can meet the system performance requirement with the lowest possible power consumption.

Description

technical field [0001] The invention relates to the storage system field of a system chip (SoC), in particular to a high-speed storage system. Background technique [0002] At present, with the advancement of integrated circuit manufacturing technology, SoC (System on Chip) has become the driving force for the diversified development of embedded products. high demands. Especially in today's popular portable wearable devices, the balance between SoC performance and power consumption is particularly important. The memory system is very important in SoC and often becomes the bottleneck restricting SoC performance and power consumption. [0003] When the system is running, different applications and the same application may have different operating loads at different times, and the bandwidth requirements for memory will also change over time. When the system needs to access the memory frequently, it will cause the contention of the memory system port and reduce the system per...
