This invention discloses a heterogeneous acceleration
system and method for analog modulation recognition of large-scale multi-channel signals, comprising: a CPU host
processing end and a GPU device computing end; the CPU host
processing end is used for asynchronous pipelined
processing of data reading, task scheduling, and result distribution, realizing parallel execution of data reading, GPU computing, and result distribution on the time axis; the GPU device computing end completes the entire process of
signal preprocessing and
deep learning model inference within the GPU memory after the original
signal is transmitted to the
video memory via the PCIe
bus, and does not exchange data with the CPU host processing end until the recognition result is generated. This invention eliminates
data transport and I / O blocking through a three-stage asynchronous pipeline architecture and a closed-loop processing link in the entire
video memory, and combines parallel preprocessing operators,
inference acceleration engines, multi-
stream scheduling mechanisms, and dynamic
video memory pools to achieve high
throughput and low latency recognition of large-scale multi-channel analog modulation signals.
