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.
