which data to be placed in the scratch pad is performed while the application is being designed, and can be done either manually using compiler directives, or automatically using a compiler. This is in contrast to cache memory systems, where the mapping of program elements is done during run...
The OS creates a task’s image by memory mapping the contents of the executable file, meaning loading and interpreting the segments (sections) reflected in the executable into memory. There are several executable file formats supported by embedded OSs, the most common including: ● ELF (...
For detailed mapping of peripheral registers, please refer to the relevant section. All the memory areas that are not allocated to on-chip memories and peripherals are considered "Reserved"). Refer to Figure 3: STM32W108 memory mapping and Table 3: STM32W108xx peripheral register boundary ...

Direct mapping: An I-cache is a mapping of memory addresses to contents; the mapping is usually implemented by a simple hash function that optimizes for the case of sequential access. Thus most processors use direct-mapped I-caches, where the low-order bits of a memory address are used to...
An abstract model for mapping virtual addresses to physical addresses in the implementation of virtual memory. (2) Swapping Swap space is a portion of hard disk used for virtual memory that is usually a dedicated partition (i.e., a logically independent section of a hard disk drive), created...
The processor delivers exceptional energy efficiency through a small but powerful instruction set and extensively optimized design, providing high-end processing hardware including a single-cycle multiplier. The Cortex-M0+ processor provides the exceptional performance expected of a modern 32- bit ...
