Hello

[size=2]

[size=2]I have to port a project that was written for the ARM11 MPcore to a project that will run on M4 (actually it is freescale Kinetis K60with M4 inside it)[/size]

[size=2]I saw in the documents of the ARM11 MP that it has 2 levelTLB, seven modes of operation (FIQ, IRQ, Supervisor, Abort, System, Undefinedmode), ...[/size]

In the documentation for the M4 I don't find any of it.

May I ask if it is exist in the M4 (K60) and what is themain differences between those two processors ?

Thanks a lot

Hi

Thanks a lot for an excellent detailed answer.
Yes, I am new to the M3 family (and to ARM in general)

I read the two chapters here
http://www.arm.com/support/resources/arm-books/the-definitive-guide-to-the-arm-cortex-m3.php

1. Is it possible to download the whole book somewhere ? (I mean, free of charge)
2. I wasn't aware of Thumb2 instruction set.
Is the integer type is 32 bit or 16 ?
If it is 32 bits, does the access to it is in one cycle or two ?
(I didn't find what is the size of the data bus)

Thanks a lot and have a great day
OM
