Hi,

I am using a pagetable base addr of 0x20026C0. I have configured for using Small Pages (that is bits[1:0] = 0b10 ) . But, I find that since the 4K page size is quite big. So, i am thinking to change the pagesize to 1K (Tiny Page Concept - bits[1:0]=0b11 ) and use the memory space efficiently.

But, my application uses 4K till now.

So, what are things that i need to consider(Takecare) if i change the 4K page size to 1K (Small page Modeil to Tiny Page Model) ?

What are the stuffs that will get effected because of changing the Small Page concept to Tiny Page ? ( I am using Arm9 Core Processor).

How far will the current existing sourcecode get affected ?
Will the CMD(Linker Command File) get affected due to this ?

Further, Normally which is better & efficient - 4K or 1K page ?
Does this selection depend upon the modules used ? Which is efficient in terms of memory management, efficient data usage, speed of access ?

Kindly share your ideas / suggestions.

Thx in advans,
