The range of memory that can be addressed is called an address space. Byte-addressable where each address identifies a single byte of storage. The previous two code examples have shown a computer architecture with a word-addressable memory. The MIPS memory model, however, is byte-addressable, not word-addressable. Each data byte has a unique address.

Each location in memory typically contains a single byte (8 bits), but could also be arranged as words (16 bits), or long words (32 bits). Byte-oriented memory is the most flexible as it also enables access to any multiple of eight bits. Note byte address 13 corresponds to the same memory block address! So a read from address 13 will also cause memory block 6 (addresses 12 and 13) to be loaded into cache block 2. To make things simpler, byte i of a memory block is always stored in byte i of the corresponding cache block. Data placement within a block 12 13 Byte Address 2 Cache Se hela listan på totalphase.com So address 0xDEAD is just the 57005 th consecutive byte in the memory (assuming they start at 0x0000 which is not always the case). To understand whether the previous or the next even address is the "corresponding one", you must learn a bit about memory organization.

Computers store digital information in the form of bits and bytes, with one byte representing the Understand memory addressing and calculate the number of The memory address space is 32 MB, or 225 (25 x log2 225 or 25 bits, to address each byte. Therefore 32 bits are required to uniquely address each 32-bit word. (b) Each word is 32 bits = 4 bytes, so if main memory is byte-addressable we have. 4 x 4 Main memory is a sequence of bytes, each with a unique address.

This binary address is defined by an ordered and finite sequence allowing the CPU to track the location of each memory byte.

The computer can access any address in memory at any time (hence the name "random access memory"). This binary address is defined by an ordered and finite sequence allowing the CPU to track the location of each memory byte.
