How memory address is generated
Did you know?
WebA physical address refers to an actual physical address in memory. A logical address is generated by the CPU and is translated into a physical address by the memory management unit(MMU). Therefore, physical addresses are generated by the MMU. 9 Why are page sizes always powers of 2? Answer: Recall that paging is implemented by breaking up an ... WebA memory address space is based on byte addressing, in which one address is assigned to one byte, and contiguous addresses arrange contiguous byte-data memory. The memory address space in a traditional computing system is linear. In general, the data type such as char (8-bit), short (16-bit), int (32-bit), and long (64-bit) are aligned onto a ...

In computing, a memory address is a reference to a specific memory location used at various levels by software and hardware. Memory addresses are fixed-length sequences of digits conventionally displayed and manipulated as unsigned integers. Such numerical semantic bases itself upon features of CPU (such … See more Physical addresses A digital computer's main memory consists of many memory locations. Each memory location has a physical address which is a code. The CPU (or other device) can use the code to access … See more Most modern computers are byte-addressable. Each address identifies a single byte (eight bits) of storage. Data larger than a single byte may be stored in a sequence of consecutive addresses. There exist word-addressable computers, where the minimal … See more Many programmers prefer to address memory such that there is no distinction between code space and data space (see above), as well as from physical and virtual memory (see above) — in other words, numerically identical pointers refer to exactly the same … See more Each memory location in a stored-program computer holds a binary number or decimal number of some sort. Its interpretation, as data of some data type or as an instruction, and use are … See more A computer program can access an address given explicitly – in low-level programming this is usually called an absolute address, or sometimes a specific address, and is known as pointer data type in higher-level languages. But a program can also use See more • Base address • Endianness • Low-level programming language • See more
