SAP703000-B03 USER'S MANUAL
Argument
First address of JPEGINFO structure
Return value
None
Description
Exchanges the data of the MCU buffer specified in dInfo member “MCU_Buff_Bptr” into
data for VRAM, and transfers the data to the VRAM coordinates specified by dInfo
member “CurrentX” and “CurrentY.”
Caution
Ensure that the contents of registers r20, r21, and r29 are not lost.
The format in which data is stored into the MCU is shown in Figure 2-11.
The size of one MCU corresponding to each sampling ratio is shown in Figure 2-12. If the VRAM is of RGB
type each pixel, converted into YCbCr format, corresponds to the figure.
The following information is required for this function.
JPEGINFO->MCU_Buff_Bptr
JPEGINFO->CurrentX
JPEGINFO->CurrentY
First address of MCU buffer
x coordinate of corresponding MCU
y coordinate of corresponding MCU
2.11 SYMBOL NAME CONVENTION
The names of the symbols used in the JPEG library are determined according to the following convention.
When you define symbols in an application, ensure that the same symbol names are not used.
