Business.
After step 309, first processor receive the second assignment instructions, for picture to be transcoded, decoding scaling is executed
Task obtains being decoded picture to be transcoded image data after scaling, as image data to be encoded.
In this step, first processor is after receiving the second assignment instructions, due to not carrying table in the second assignment instructions
Show the code identification encoded according to the first coded format, can determine and only need to be implemented decoding scaling subtask, without
Need to be implemented coding subtask.
The second task of step 310, first processor to second processor return for the second assignment instructions responds, and second
Task response indicates to have executed decoding scaling subtask.
Further, the second task response in can also carry for picture to be transcoded be decoded scaling after obtain to
Encoded picture data, the second task response in can also carry for picture to be transcoded be decoded scaling after obtain it is to be encoded
The second storage location of image data in memory.
Step 311, second processor directly acquire progress from the response of the second task after receiving the response of the second task
Image data to be encoded after decoding scaling, or obtain above-mentioned second storage location from the response of the second task, and from memory
In the second storage location obtain be decoded scaling after image data to be encoded.
Step 312, second processor are to the above-mentioned image data to be encoded being decoded after scaling got, according to the
Two kinds of coded formats are encoded, and the transcoding picture encoded according to second of coded format is obtained.
In this step, second of coded format can be other coded formats in addition to webp coded format, for example, can
To be jpg coded format, png coded format, bmp coded format etc..
In embodiments of the present invention, first processor can be FPGA, and second processor can be CPU.It can exist in advance
The execution logic that enough decoding scalings are disposed on FPGA is held with the first coded format, such as the coding of webp coded format
Row logic, so that decoding scaling process and complicated webp cataloged procedure are executed by first processor FPGA, the volume of extended formatting
Code process, such as jpg cataloged procedure are executed by second processor CPU, so that the picture transcoding of two kinds of formats has shared decoding contracting
The execution logic put can realize that the picture of multiple format turns in the case where not increasing hardware device in the same apparatus
Code.Moreover, webp coding is 10 times of jpg encoder complexity or more, gives complicated webp coding to FPGA and complete, reasonably
Deploy the computing resource of processor.
