Background:

Real-time in situ image analytics demand low latency for intelligent neural network inference.
Graphic processing unit (GPU)-accelerated platforms offer high throughput but lack suitability for latency-sensitive tasks.

Purpose of the Study:

To demonstrate a unified system using field-programmable gate array (FPGA) processing for low-latency intelligent image analytics.
To bridge the gap between hardware processing and algorithm deployment for real-time applications.

Main Methods:

Developed a high-performance reconfigurable computing platform utilizing FPGA processing.
Implemented a deeply pipelined hardware design for concurrent computation of quantized convolutional neural network (QCNN) layers.
Performed inference operations on image streams as they are produced.

Main Results:

Achieved ultralow classification latency of 34.2 milliseconds for label-free human peripheral blood mononuclear cell (PBMC) subtype classification.
Attained over 95% end-to-end accuracy using the QCNN.
Processed images at a throughput exceeding 29,200 cells/second.

Conclusions:

FPGA-based processing platforms can meet stringent latency requirements for real-time intelligent image analytics.
The proposed modular QCNN design is adaptable for various latency and resource needs.
This system effectively integrates hardware acceleration with advanced image analysis for biological applications.
