starts at bit 24, etc. The start pixel, P2, is in the word at address 0x0000 and has a beginning
bit position of 16. This makes 16 = 0x10 the value that is used for the SPEL field in the

Let the starting SDRAM address of the destination image be 0x0030.
Pixel 2 starts at bit 16, Pixel 3 starts at bit 34, etc. The start pixel, P2, is in the word at address
0x0030 and has a beginning bit position of 16. This makes 16 = 0x10 the value that is used
for the SPEL field in the
The end pixel, P5, is in the word at address 0x0034 and has a beginning bit position of 8. This
makes 8 = 0x8 the value that is used for the EPEL field in the
For a Block Copy where 8 pixels are transferred per scan line, let the starting SDRAM
address of the source image be 0x0000.
starts at bit 16, etc. The start pixel, P0, is in the word at address 0x0000 and has a beginning
bit position of 0. This makes 0 = 0x0 the value that is used for the SPEL field in the
“SRCPIXELSTRT”
Note:The word count for this example would be: 2 - 1 = 1 words, since P5 ends in the 2nd word.
