Large-Scale Blood Analyzer

Industry: Medical Devices

Solution Overview: Blood analyzers are a popular type of medical analysis instrument in China's medical device industry. Due to their widespread adoption, the market demand is substantial. Large-scale blood analyzers have relatively complex hardware architectures, typically requiring a combination of ARM and FPGA. This solution implements the necessary hardware functions at the ARM level, enabling medical device customers to rapidly develop complete system solutions.

Solution Characteristics: This is a commonly used hardware architecture for large-scale blood analyzers. Blood analyzers are generally categorized into three-part and five-part differential types (the three-part differential classifies white blood cells into neutrophils, lymphocytes, and intermediate-sized granulocytes; the five-part differential further divides them into neutrophils, lymphocytes, eosinophils, basophils, and monocytes). The FPGA signal board acquires analog signals of white blood cells, red blood cells, and platelets via impedance or laser scatter methods (white blood cells only), and converts them into digital signals. The FPGA driver board primarily controls motors, valves, and other fluidic pathway components. The ARM architecture handles data processing, result analysis, and display output. Communication between ARM and FPGA, as well as between FPGAs, is achieved through the GPMC bus. By using Xinming’s AM5728 core board, users can significantly reduce ARM-side development effort, focusing only on FPGA development, thereby saving considerable R&D and time costs.
