WebThe registers in a 32 bit computer are 32 bits wide, for example. Each CPU (logical core) gets its own set of registers. The term "Virtual Cores" or "Threads" stems from the idea of including multiple (independent) sets of registers for each physical CPU (core). eg; "8 cores 16 threads" == 8 CPUs and 16 sets of registers (2 per core). In computing, a physical address (also real address, or binary address), is a memory address that is represented in the form of a binary number on the address bus circuitry in order to enable the data bus to access a particular storage cell of main memory, or a register of memory-mapped I/O device. See more In a computer supporting virtual memory, the term physical address is used mostly to differentiate from a virtual address. In particular, in computers utilizing a memory management unit (MMU) to translate memory addresses, … See more The direct memory access (DMA) feature allows other devices in the mother board besides the CPU to address the main memory. Such devices, therefore, also need to have a knowledge of physical addresses.
