If a TSR is created in assembly langauge, the programmer has exact control over the use of memory and can omit the heap area and place the initialization code at the end of the segment (where it can be released after initialization). If a TSR is created in C, the small-memory model must be used. WebMost registers are memory mapped; that is, the register has an address in the memory space. A memory-mapped register can be referred to in assembly language in two different ways: either by referring to its mnemonic name or through its address. Program counter and control flow.

The memory attributes available in Cortex®-M processors include the following: Bufferable: A write to … WebMost previous work on memory mapping and allocation of multiport memories has been done in the context of data path synthesis and has focused on purely data flow designs (no control constructs) [9, 10, 11]. These algorithms do not deal with unknown data access patterns because no control flow is involved. Memory mapping

There’re three types of buses required for I/O communication: address bus, data bus, and control bus. We assign an address to each I/O device for the CPU to communicate to that device using its address.
