  2. Memory map - Wikipedia

    en.wikipedia.org/wiki/Memory_map

    In virtual memory implementations and memory management units, a memory map refers to page tables or hardware registers, which store the mapping between a certain process's virtual memory layout and how that space relates to physical memory addresses. In native debugger programs, a memory map refers to the mapping between loaded executable(or ...

  3. Memory-mapped I/O and port-mapped I/O - Wikipedia

    en.wikipedia.org/wiki/Memory-mapped_I/O_and_port...

    Memory-mapped I/O is preferred in IA-32 and x86-64 based architectures because the instructions that perform port-based I/O are limited to one register: EAX, AX, and AL are the only registers that data can be moved into or out of, and either a byte-sized immediate value in the instruction or a value in register DX determines which port is the source or destination port of the transfer.

  4. Memory mapping - Wikipedia

    en.wikipedia.org/wiki/Memory_mapping

    Memory-mapped I/O, an alternative to port I/O; a communication between CPU and peripheral device using the same instructions, and same bus, as between CPU and memory; Virtual memory, technique which gives an application program the impression that it has contiguous working memory, while in fact it is physically fragmented and may even overflow ...

  5. Memory management unit - Wikipedia

    en.wikipedia.org/wiki/Memory_management_unit

    A 68451 MMU, which could be used with the Motorola 68010. A memory management unit (MMU), sometimes called paged memory management unit (PMMU), [1] is a computer hardware unit that examines all memory references on the memory bus, translating these requests, known as virtual memory addresses, into physical addresses in main memory.

  6. AVR microcontrollers - Wikipedia

    en.wikipedia.org/wiki/AVR_microcontrollers

    The debugWire interface enables debugging using only one pin (the Reset pin), allowing debugging of applications running on low pin-count microcontrollers. The JTAGICE mkII connects using USB, but there is an alternate connection via a serial port, which requires using a separate power supply.

  7. Input–output memory management unit - Wikipedia

    en.wikipedia.org/wiki/Input–output_memory...

    In computing, an input–output memory management unit (IOMMU) is a memory management unit (MMU) connecting a direct-memory-access–capable (DMA-capable) I/O bus to the main memory. Like a traditional MMU, which translates CPU -visible virtual addresses to physical addresses , the IOMMU maps device-visible virtual addresses (also called device ...

  8. Atmel AVR instruction set - Wikipedia

    en.wikipedia.org/wiki/Atmel_AVR_instruction_set

    The Atmel AVR instruction set is the machine language for the Atmel AVR, a modified Harvard architecture 8-bit RISC single chip microcontroller which was developed by Atmel in 1996. The AVR was one of the first microcontroller families to use on-chip flash memory for program storage.

  9. Special function register - Wikipedia

    en.wikipedia.org/wiki/Special_Function_Register

    Special function registers are in the upper area of addressable memory, from address 0x80 to 0xFF. This area of memory cannot be used for data or program storage, but is instead a series of memory-mapped ports and registers. All port input and output can therefore be performed by memory move operations on specified addresses in the SFR region.
