The instruction fetch unit (IFU) contains the instruction cache controller and its associated linefill buffer. The Cortex-A53 MPCore instruction cache is 2-way set associative and uses virtually-indexed physically-tagged (VIPT) cache lines holding up to
Instruction fetch: fetch one instruction from memory each time(取指令:每次从内存中获取指令) Instruction execute: execute each instruction(指令执行:执行每一条指令) Program execution halts only if the machine is turned off, some sort of unrecoverable error occurs, or a program instruction that halts ...

Structural hazardsoccur when the circuits implementing different hardware functions are needed by two or more instructions at the same time. For example, a single memory unit is accessed during theinstruction fetchstage when an instruction is retrieved from memory, and it is also accessed during the...

For example, the IP/PC register mentioned earlier stores the address of the next location in memory from which the CPU will fetch the next instruction. Such numeric addressing is usually referred to as physical addressing and ranges from 0 to the amount of physical memory installed. The CPU ...
For example, during the fetch stage 902, one or more instructions are fetched from instruction memory, and during the decode stage 906, the one or more fetched instructions may be decoded, addresses (e.g., load store unit (LSU) addresses) using forwarded register ports may be generated, ...
