  2. Bus (computing) - Wikipedia

    en.wikipedia.org/wiki/Bus_(computing)

    An address bus is a bus that is used to specify a physical address. When a processor or DMA-enabled device needs to read or write to a memory location, it specifies that memory location on the address bus (the value to be read or written is sent on the data bus). The width of the address bus determines the amount of memory a system can address.

  3. System bus - Wikipedia

    en.wikipedia.org/wiki/System_bus

    A system bus is a single computer bus that connects the major components of a computer system, combining the functions of a data bus to carry information, an address bus to determine where it should be sent or read from, and a control bus to determine its operation. The technique was developed to reduce costs and improve modularity, and ...

  4. Message passing - Wikipedia

    en.wikipedia.org/wiki/Message_passing

    In computer science, message passing is a technique for invoking behavior (i.e., running a program) on a computer.The invoking program sends a message to a process (which may be an actor or object) and relies on that process and its supporting infrastructure to then select and run some appropriate code.

  5. Control bus - Wikipedia

    en.wikipedia.org/wiki/Control_bus

    In computer architecture, a control bus is part of the system bus and is used by CPUs for communicating with other devices within the computer. While the address bus carries the information about the device with which the CPU is communicating and the data bus carries the actual data being processed, the control bus carries commands from the CPU and returns status signals from the devices.

  6. Addressing mode - Wikipedia

    en.wikipedia.org/wiki/Addressing_mode

    Computer architectures vary greatly as to the number of addressing modes they provide in hardware. There are some benefits to eliminating complex addressing modes and using only one or a few simpler addressing modes, even though it requires a few extra instructions, and perhaps an extra register.

  7. Interface (computing) - Wikipedia

    en.wikipedia.org/wiki/Interface_(computing)

    An interface is thus a type definition; anywhere an object can be exchanged (for example, in a function or method call) the type of the object to be exchanged can be defined in terms of one of its implemented interfaces or base-classes rather than specifying the specific class. This approach means that any class that implements that interface ...

  8. Mano machine - Wikipedia

    en.wikipedia.org/wiki/Mano_machine

    The Mano machine is a computer theoretically described by M. Morris Mano.It contains a central processing unit, random access memory, and an input-output bus.Its limited instruction set and small address space limit it to use as a microcontroller, but it can easily be expanded to have a 32-bit accumulator register, and 28-bit addressing using a hardware description language like Verilog or ...

  9. I3C (bus) - Wikipedia

    en.wikipedia.org/wiki/I3C_(bus)

    I²C Extended (10-bit) Addresses. All devices on an I3C bus are addressed by a 7-bit address. Native I3C devices have a unique 48-bit address which is used only during dynamic address assignments. If clock stretching is needed, a "I3C Hub" can be used to bridge between the I3C network and the I²C target device. [17]
