[C5535]Huge size table handling in spi flash memory?

Sung-IL

Dear Team,

I'm looking for the method to handle huge size data(like constant table) in C5535, and expecting this huge size table will be in flash memory.

Actually, I'm checking to implement graphic library, but the big problem is if C5535 can handle huge size of font data(4Mbit or larger) of graphic library residence in external SPI flash memory.

Code size is small, but the problem is huge table size and only some piece of this huge tables will be used.

I found below, but it would be helpful if I can get more details.

Thanks and Best Regards,

SI.

Hi SI,

How large are the pieces of font data that you need to pull out of the table? Can you just retrieve only what you need at a time?

Hi Lali,

Maximum size of table will be around 8MB, and the amount of pieces of font data can be around 200 Bytes.
Yes. they can retrieve only what they need at a time, but they want to access it using like memory I/O.

Thanks and Best Regards,
SI.
