Module1 Lesson 2 Readings In Philippine History Pdf Memory address in a computer using virtual memory, accessing the location corresponding to a memory address may involve many levels. in computing, a memory address is a reference to a specific memory location in memory used by both software and hardware. [1]. Unaligned addressing depending upon its underlying computer architecture, the performance of a computer may be hindered by unaligned access to memory. for example, a 16 bit computer with a 16 bit memory data bus, such as intel 8086, generally has less overhead if the access is aligned to an even address.
Readings In The Philippine History Lesson 1 Pdf Primary Sources For example, a computer might use 32 bit addresses with byte addressing in its instruction set, but the cpu's cache coherence system might work with memory only at a granularity of 64 byte cache lines, allowing any particular cache line to be identified with only a 26 bit address and decreasing the overhead of the cache. Memory mapped i o uses the same address space to address both main memory [a] and i o devices. [1] the memory and registers of the i o devices are mapped to (associated with) address values, so a memory address may refer to either a portion of physical ram or to memory and registers of the i o device. Address space in computing, an address space defines a range of discrete addresses, each of which may correspond to a network host, peripheral device, disk sector, a memory cell or other logical or physical entity. for software programs to save and retrieve stored data, each datum must have an address where it can be located. Memory address register in a computer, the memory address register (mar) [1] is the cpu register that either stores the memory address from which data will be fetched to the cpu registers, or the address to which data will be sent and stored via system bus.

Also, 64 bit central processing units (cpu) and arithmetic logic units (alu) are those that are based on processor registers, address buses, or data buses of that size. a computer that uses such a processor is a 64 bit computer. from the software perspective, 64 bit computing means the use of machine code with 64 bit virtual memory addresses. 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. for example, a system with a 32 bit address bus.
