What is Vector Table Offset Register (VTOR) in Arm Cortex-M series?

The Vector Table Offset Register (VTOR) is a key register in Arm Cortex-M series processors that controls the location of the vector table in memory. The vector table contains the reset value for the stack pointer and the exception vector entries which hold the addresses of interrupt service routines. By changing the VTOR, the vector

What is ECC for TCM and Cache in Arm Cortex-M series?

ECC stands for Error Correcting Code. It is a mechanism used to detect and correct data corruption errors in computer memory systems. ECC is important for system reliability and data integrity, especially in mission-critical applications. In Arm Cortex-M series processors, ECC can be enabled for on-chip SRAM memories like Tightly Coupled Memory (TCM) and caches.

What is Data TCM (DTCM) Memory in Arm Cortex-M series?

Data TCM (DTCM) is a small, fast memory located inside the Cortex-M processor that can be used for time-critical data accesses. It allows frequently accessed data to be stored close to the processor, reducing access latency and improving performance. Overview of Tightly Coupled Memories in Cortex-M The Cortex-M series of processors contain small memories called

What is Instruction TCM (ITCM) Memory in Arm Cortex-M series?

Instruction TCM (ITCM) is a small, fast memory region that is located within the Cortex-M processor itself. It allows frequently used code to be stored on-chip for quick access, improving performance by reducing the need to fetch instructions from slower off-chip memory. Overview of ITCM The Cortex-M series of processors from Arm are 32-bit RISC
