Embodiment 1

[0079] In order to verify the feasibility and effectiveness of the present invention, a system verification platform was built in the present invention, and a preliminary simulation and a large number of measurement experiments were performed. The experimental blood samples are derived from human blood samples from the hospital laboratory. The system verification platform is a self-developed hardware system. The main control chip of the verification system is the Zynq020-CLG484 device of Xilinx 28nm process. The chip integrates FPGA and 667Mhz dual-core ARM Cortex -A9 processor, equipped with 1GBDDR3 cache and 8GB eMMC storage outside the chip.

[0080] First, a SoC-based white blood cell counting system is proposed, which can quickly and efficiently implement image algorithms to accelerate calculations while reducing development costs, such as figure 1 As shown, the system includes a SOC-FPGA, and the image acquisition module of the SOC-FPGA collects the image to be analyzed fro...

Embodiment 2

[0121] Such as Figure 5 As shown, a SOC-based white blood cell counting method implemented according to the above white blood cell counting system, such as Image 6 It is the correlation fitting between the test result of the method of the present invention and the test result of the Mindray biochemical analyzer, and the correlation can reach 0.992. Therefore, the method has good performance and reduces the equipment cost while ensuring the white blood cell counting speed and accuracy. The method includes:

[0122] Step 1. The SOC-ARM initializes the configuration of the image sensor, uses the SOC-FPGA to construct the register group, and collects the image to be analyzed from the image sensor through the image acquisition module of the SOC-FPGA.

[0123] In order to make full use of the flexibility of SOC-ARM control and reduce the consumption of SOC-FPGA logic resources, the serial data communication is used to configure the external image sensor through the I2C interface, and th...

Abstract

The invention discloses an SOC-based leukocyte counting system. The system is characterized by comprising an SOC-FPGA, an SOC-ARM and a cache module, wherein an image collection module of the SOC-FPGAcollects a to-be-analyzed image from an image sensor in real time, and data of the to-be-analyzed image is preprocessed; the SOC-ARM comprises a DDR3 controller, is used for completing initializationconfiguration and dynamic configuration of the image sensor, data communication, image caching and display and software and hardware interaction time sequence control and is connected with the SOC-FPGA through an AMBA AXI4-Lite bus; and the cache module realizes caching of the data of the to-be-analyzed image by the adoption of a DMA data transmission IP core and is connected with the DDR3 controller through an AMBA AXI4 bus interface. Through the counting system and method, development cost can be lowered while image algorithm acceleration computing is realized quickly and efficiently.

Description

Technical field [0001] The invention relates to a white blood cell counting system and method, in particular to a white blood cell counting system and method based on SOC. Background technique [0002] In recent years, thanks to the rapid development of POCT, or point-of-care testing, point-of-care testing, portable white blood cell counting equipment has received widespread attention due to its convenient advantages. Limited by the hardware processing system, its cost and detection accuracy are often inversely proportional, which greatly limits the wide application of portable leukocyte equipment. At the same time, processor performance cannot be increased in accordance with Moore's Law, and data growth requires more computational performance than the rate of growth in accordance with Moore's Law. The processor itself cannot meet the performance requirements of high-performance computing application software, and there is a gap between requirements and performance. The main wa...
