Cpu core tunnel.9/8/2023 The electrons, transistors, digital logic gates, and instruction set architecture are your blood, bones, tissues, and organs respectively. In this analogy, you can think of "software" as your personality, or just " you" psychologically speaking. You can think of the CPU as a "brain", because it controls how data flows throughout the entire computer system, under the influence of instructions, which are called "programs"! Running the most powerful components (or overclocking those. Physically preform the processing ( ex: move data, combine pieces of information/data together logically, arithmetically add pieces of data together etc.) Posted: 6:54 am Computers are some of the most flexible, powerful devices in the world, but that power can come at a cost. Direct the processing of information ( take input from a keyboard, combine it with values from a hard drive, and then spew it out into a printer or graphics card)Ģ. If you think about what a computer really is, you realized that there's essentially 2 jobs that all computer systems must accomplish:ġ. This can be useful for debugging or exploiting computer software. You can use tools like GDB to inspect and manipulate the registers while a program is running. eg "8 cores 16 threads" = 8 CPUs and 16 sets of registers (2 per core). The term "Virtual Cores" or "Threads" stems from the idea of including multiple (independent) sets of registers for each physical CPU (core). The registers in a 32 bit computer are 32 bits wide, for example.Įach CPU (logical core) gets its own set of registers. The size of a register can be 8, 16, 32, or 64 bits. Sets of registers work together to facilitate the most basic units of computation that take place in a computer. I/O Register (INTR / OUTR): stores input and output data Temporary Register (TR): stores temporary data Address Register (AR): hold addresses to primary memory Instruction Register (IR): stores instruction Program Counter (PC): stores address of next instruction Acumulator (ACC): stores data for all ALU operations What are the different types of this special memory?Ī: Types of registers included will vary by processor, but usually some combination of What is the special memory used only by the CPU?Ī: Registers (collectively referred to as L1 Cache)
