AI Technical Summary
The performance of CNN accelerators is limited by the upper limits of off-chip storage bandwidth and computing resources, resulting in uneven data transmission, underutilization of storage bandwidth, and slowing down system performance.
By using a bandwidth-adaptive data transmission method, and employing modules such as an automatic address generation module, an AXI driver module, an automatic interpolation module, and a FIFO driver module, the system can sense the data transmission status, dynamically adjust the data transmission strategy, insert predetermined values to optimize the data flow, and improve data transmission efficiency.
The data transfer efficiency between the CNN accelerator and the external storage device was optimized, reducing computation latency and improving the overall system performance.
