Embodiment 1
[0042] Such as figure 1 As shown, a fast retrieval method of an on-board solid-state memory comprises the following steps:
[0043] S1. After the on-board solid-state memory is powered on, the software logic enters the idle state after initialization and waits to receive external commands;
[0044]S2. After receiving the retrieval and playback instruction from the outside, judge whether the retrieved image file exists; if yes, proceed to step S3; if not, proceed to step S8;
[0045] S3. Send the index address to the FPGA, and receive the index information returned by the FPGA;
[0046] S4. Judging whether the image information range of the summary index information in the index information overlaps with the retrieval range of the retrieval playback command, if yes, then retain the index address, if not, then do not retain the index address; return to step S3 until all indexes The addresses are all retrieved once, and enter step S5;
[0047] S5, judge whether there is the in...
Embodiment 2
[0057] Such as image 3 As shown, a fast retrieval method for on-board solid-state memory, the specific implementation process is as follows:
[0058] Taking receiving a search and playback instruction as an example, the specific implementation of the present invention will be further introduced.
[0059] (1) After the memory solid-state machine is powered on, the software logic enters the idle state after initialization and waits to receive external instructions.
[0060] (2) After receiving the search and playback command from the outside, it is judged whether the retrieved image file exists. If the file does not exist, go directly to step 6; if the file exists, it is ready to be retrieved as required, and go to step 3.
[0061] (3) Send the index address to the FPGA to obtain the image-related information stored in the address, judge the summary information in the received index information, and keep the index if the image information range in the summary information over...
