PA6488 Developer's Guide - Data Structure     Data Type See in Palmmicro software API data type.   Data Performance Make sure index variables are signed integers, example: int i; When parallel processing is not possible or obvious, use int or UINT where is possible for best performance and size. Make all struct and union data type 64-bit data alignment for best performance. Make all items in struct in 32-bit group to avoid compiler bug, see known bugs page.   Data Alignment The total size of struct is 64-bit aligned. Struct inside struct is 64-bit aligned. Arrays larger than 8 bytes inside struct is 64-bit aligned as possible. 32-bit int, pointer inside struct is 32-bit aligned. 16-bit data inside struct is 16-bit aligned. Avoid using 8-bit data inside struct, but use it when necessary.   Related Information Data structure of PA3288.
