Problems solved by technology
Configuration may not be successful due to channel and transport issues, reliability of peripheral cache devices, etc.
In the configuration method of the prior art, if the configuration is unsuccessful, the entire system will not be able to determine which link is the problem, and can only use the self-test method of the whole machine system to verify which link is the problem
But in this way, the scene where the problem occurred was changed, so that the root cause of the problem could not be found.

Embodiment Construction
[0016] like figure 1 As shown, in one embodiment of the present invention, the method for configuring a programmable device online in an electronic equipment system (such as an ultrasound imaging system, etc.) includes: Step 22: Preprocessing the original configuration data; Step 24: Preprocessing the configuration data stored in the memory; step 26: read the pre-processing configuration data from the memory; step 28: verify processing; and step 30: configure the programmable device with the pre-process configuration data that has passed the verification. Each step is described in detail below.
[0017] Step 22: Preprocessing the original configuration data;
[0018] As mentioned above, in the prior art, when configuring a programmable device, the unprocessed "naked" configuration data is usually directly used. In the embodiment of the present invention, the raw configuration data is not directly used to configure the programmable device, but the raw configuration data (refe...

The embodiment of the present invention discloses a method for online configuration of a programmable device, including: inserting check code data into the original configuration data of the programmable device to obtain pre-processing configuration data; storing the pre-processing configuration data in a memory; Reading the pre-processing configuration data from the memory and using the pre-processing configuration data to configure the programmable device; wherein, the process of configuring the programmable device includes: performing at least one check on the pre-processing configuration data according to the check code data. In the embodiment of the present invention, check code data is added to the configuration data, and each node in the configuration process checks the configuration data according to the check code data. In this way, when a configuration failure occurs during the configuration process, the location of the failure that causes the configuration failure can be conveniently located, thereby facilitating the user to determine the cause of the configuration failure.
Description
technical field [0001] The invention relates to a method for configuring programmable devices online. Background technique [0002] At present, programmable devices such as FPGA (Field Programmable Gate Array), DSP (Digital Signal Processor), MCU (Micro Control Unit) and so on are usually used in a large number of medical ultrasound imaging equipment. These programmable devices usually use software to implement hardware functions, so they need to be configured online before they can work normally. Programmable devices are usually used as sub-parts of the whole machine system. After the whole machine is powered on, the corresponding configuration data (configuration file) is transmitted to them, and the corresponding devices are configured according to the configuration data, and then the corresponding functions can be completed. [0003] Because the programs designed by these programmable devices are usually relatively large, the configuration data will be relatively large....
