Abstract
The invention discloses a method for decoding audio/video data. The method comprises the following steps that: a first program informs a second program to initialize; the second program acquires a frame datum to be decoded and decodes after finishing the initialization, stores the decoded frame datum into a first memory and sends a first instruction; and the first program reads the decoded frame datum from the first memory through the first instruction and clears the first instruction. In the invention, datum reading is controlled through a flag bit instruction, a flag bit can be sent only after the decoding is finished and the frame datum is written in or after a datum to be coded is written in, correspondingly, the decoded frame datum or the frame datum to be coded is read after the flag is received, thus, the condition of error datum reading caused by not finishing writing in the frame datum during datum reading is avoided, and meanwhile, the problem of more access times of IO (Input/Output) is solved.

Step 44: the first program reads described decoded frame data by described the second instruction to the second internal memory, and the second instruction is emptied.
Above step 41 to 44 be circulation process, the first program cycle deposits frame data to be decoded in the first internal memory and the second internal memory, so corresponding the second program also reads and decodes with regard to accordingly to the first internal memory and the second internal memory, and deposits decoded frame data in corresponding the first internal memory and the second internal memory.
This embodiment further increased the process that datacycle is write to the first internal memory and the second internal memory on the basis of embodiment 1, so just improved program and write and the speed of reading out data, improved the efficiency of decoding.
3 processes that datacycle write to the first internal memory and the second internal memory that provide of enforcement also can, for embodiment 2, be not repeated at this.
Embodiment 4, the invention provides a kind of method of coding audio/video data referring to Fig. 5:
Step 50: the 3rd program is notified the 4th program initialization;
Wherein step 50 concrete methods of realizing is:
Step 501, the 3rd program in the 3rd internal memory, notifies the 4th program to read needed data to be decoded Parameter storage;
Step 502: the 4th program to the three internal memories read described parameter and carry out initialization, and notify the 3rd program initialization to complete;
Step 51: notify the 3rd program after the 4th program initialization completes, frame data to be encoded are stored to the 3rd internal memory by the 3rd program, and send the 3rd instruction;
Step 52: the 4th program reads described frame data to be encoded by the 3rd instruction and encodes, and the 3rd instruction is emptied.
Describe as an example of needs coded data MP3 example below, referring to Fig. 6.For example the 3rd program is 64 programs, and the 4th program is 32 programs.
Step 601:64 position program in the 3rd internal memory, and sends the needed Parameter storage of mp3 file of coding start and notifies 32 programs to read;
Step 602:32 position program reads the needed parameter of decoding MP3 to the 3rd internal memory after receiving start, and carries out initialization, sends 64 program initializations of ready instruction notification and complete after initialization completes;
Step 603:64 position program receives after the information that completes of ready initialization that 32 programs send, and frame MP3 data are write to the 3rd internal memory, sends read1 and notifies 32 programs to read;
Step 604:32 position program to the three internal memories read described frame MP3 data to be encoded and encode; After having encoded, read1 is emptied.
In above embodiment, the present invention is by flag bit the 3rd instruction, namely read1 controls reading out data, only have after 64 programs write frame data to be encoded and just send flag bit read1,32 programs also only can just can go internal memory to read frame data to be encoded receiving after flag read1 so, and while so just having avoided 32 programs to remove the first internal memory read data, 64 programs have not also write frame data to be decoded and cause the situation of reading out data mistake.
Corresponding to embodiment 3, on the basis of embodiment 4, the 3rd program can also further be stored to the 3rd internal memory and the 4th internal memory by a frame data to be encoded circulation, connects so step 53 and continues as:
