I am performing JPEG Decode operation with ADSP-BF707 processor. Decode operation takes longer than I expected.
I did the encode and decode operation on the same image as BF707. The processing times are as follows. (Image size 300x380 YUV420)
Encode time = 10.8ms
Decode time = 44.9ms
In performance tests on documents "KT-570 JPEG Decoder Product Specification" and "KT-571 JPEG Encoder Product Specification" , the difference between encode and decode times is not high.
What is the cause of the problem?How can I solve?I would like your advice.
I found the cause of the problem.The problem was corrected by performing the data cache settings as shown in the illustration. (Data Cache set "Enable data cache on bank A")Those who experience a similar problem can make this adjustment first.
