Web2.5.2-rmk5: This is the first kernel that contains a major shake up of some of the major architecture-specific subsystems. Firstly, it contains some pretty major changes to the way we handle the MMU TLB. Each MMU TLB variant is now handled completely separately - we have TLB v3, TLB v4 (without write buffer), TLB v4 (with write buffer), and ...

I … WebThe ARM Cortex-M is using an NVIC (Nested Vectored Interrupt Controller). The NVIC uses a vector table which consists of 32-Bit vector entries. A vector entry stores the address of the according interrupt handler routine. The first entry in the vector table is not an actual interrupt routine address but the initial stack pointer value.
