Problems solved by technology

[0004] However, the above-mentioned configuration methods are all fixed configuration methods, that is, it is impossible to dynamically adjust the use of FPGA logic resources in real time according to the working status of the ultrasound system, so that FPGA logic resources cannot be used more efficiently and reasonably, and it is impossible to achieve more on the same FPGA logic resources. Complex ultrasound system functions, or lower FPGA power consumption control on the same ultrasound system functions

example 1

[0058] Example 1: If the current scan mode information is the single B-scan mode, and the received scan mode information is also the single B-scan mode, then the judgment result is that the received scan mode information is the same as the current scan mode information, and not It needs to be reconfigured (ie False), and continue to use the FPGA configuration file corresponding to the current scan mode information;

example 2

[0059] Example 2: If the current scanning mode information is a single B-scanning mode, and the received scanning mode information is a PW scanning mode, then the judgment result is that the received scanning mode information is different from the current scanning mode information, and the Obtain the FPGA configuration file corresponding to the received scan mode information (ie PW scan mode) in a plurality of FPGA configuration files stored;

example 3

[0060] Example 3: If the current scanning mode information is a single B-scanning mode, and the received scanning mode information is a B+C scanning mode, then the judgment result is that there is overlap between the received scanning mode information and the current scanning mode information Scan mode information (i.e. B-scan mode) and the received scan mode information includes the current scan mode information, then obtain the scan mode information (i.e. C-scan mode) corresponding FPGA configuration file, and directly add the FPGA configuration file corresponding to the C-scan mode obtained to the current FPGA configuration file in the reconfiguration;

Abstract

The invention discloses a method and a device for re-configuring FPGA in an ultrasonic system. The method and device for re-configuring the FPGA in the ultrasonic system are suitable for the technical field of information processing. The method for re-configuring the FPGA in the ultrasonic system includes that acquiring an FPGA configuration file corresponding to received scanning mode information from a plurality of pre-stored FPGA configuration files when the scanning mode information is received; re-configuring the current FPGA according to the acquired FPGA configuration file. The method and device for re-configuring the FPGA in the ultrasonic system are capable of dynamically regulating the use of FPGA logic resource according to the working condition of the ultrasonic system, and the power consumption of the FPGA is lowered.

Description

technical field [0001] The invention belongs to the technical field of information processing, and in particular relates to a method and device for FPGA reconfiguration in an ultrasound system. Background technique [0002] In the existing ultrasound system, Field-Programmable Gate Array (FPGA) is used to realize different functions, such as beamforming, front-end digital signal processing, back-end image processing and other functions. Different functions correspond to FPGA configurations are different. [0003] In most current ultrasound systems, the FPGA is only configured once when the system is powered on, and will not be configured again during operation, and the same configuration is used in all scan modes. However, in some ultrasound systems based on the PC platform, incremental configuration can be used. For example, when the system is powered on (i.e., starting up), it is first configured to quickly detect and identify the peripheral component high-speed expansion...
