Cross compile gcc source for arm-cortex-m3 (I am using LPC1343) in Ubuntu/BOSS

This post includes methods to cross compile gcc source against ARM-Cortex-M3 target and use it to compile a program to blink LED in an LPC1343 board. The environment I used is Ubuntu 10. It may work with other platforms also. I tested this in Ubuntu lucid lynx and BOSS-2.6.22-3-486 ( Bharat Operating System Solutions ). This I tried referring this blog post.

Virtual memory and memory management unit

This post is incomplete. Would update later... ;)

Address space of a process can exceed physical memory using virtual memory.
I can use the addresses in the secondary memory for realisation of a memory space bigger than that is available in terms of SDRAM on the embedded system.
Multiple processes resides in main memory, each process with its own address space.
Only active code and data is actually in the memory
Another property provided through that of virtual memory is protection. One process should not interfere with another process. Because they operate in different address spaces. This we can make sure once we have implemented virtual memory. Because then we have a clear partitioning of address spaces of different processes.
