4 Functional Description

– YUV422: the horizontal resolution of the output decoded image is the multiples of 16 and the

vertical resolution is multiples of 8, i.e., 150 × 150 images with an output resolution of 160 × 152

– YUV420: both the horizontal and vertical resolutions of the output decoded image are multiples of

16, i.e., 150 × 150 images with an output resolution of 160 × 160

• Performance:

– Still image decoding: up to 4K resolution

– Dynamic image decoding: up to 1080P@40fps, 720P@70fps (excluding header parsing time)

Pin Assignment

The JPEG Codec does not interact directly with IOs, so it has no pins assigned.
