CPU is main part of computer,It processes the data using the registers inside the CPU. These are of different types and have different purpose of use. Due to these registers the CPU done processing.
Bus
The CPU primarily uses machine language, which consists of binary instructions. Machine language is the lowest-level programming language, represented in binary code (0s and 1s) that the CPU can directly execute. Higher-level programming languages are ultimately translated into this binary format so that the CPU can perform the specified operations.
The CPU fetches data and instructions from the computer's memory, primarily the Random Access Memory (RAM). When a program is executed, its instructions and the data it requires are loaded from storage (like a hard drive or SSD) into RAM, where the CPU can quickly access them. The CPU uses the memory address provided by the program counter to retrieve the relevant instructions and data.
Memory mapped IO uses a portion of RAM to handle IO requests. In this manner, instructions the CPU uses for reading and writing memory can also be used for IO, reducing the circuitry needed. This makes the CPU simpler, cheaper and more effecient.
The CPU executes program instructions.
ROM (Read-Only Memory) and RAM (Random Access Memory) interact with the CPU by providing different types of data storage. ROM contains permanent instructions essential for booting the system, while RAM provides temporary storage for data and programs that the CPU actively uses during operation. The CPU retrieves instructions and data from RAM for processing, and it may access ROM for essential firmware instructions if needed. This collaboration ensures that the CPU can execute tasks efficiently by utilizing the fast access speed of RAM and the stable data provided by ROM.
main memory provides buffers.buffers are the places where program execution takes place.but the CPU is provided with registers(memory units) there CPU can accomodate instructions and the data on which theses instructions are to be operated.from the main memory CPU fetches the instructions one by one and the instruction is processed in the CPU and then sends back the result to the main memory......i think so.thank u
The CPU - Central Processing Unit, or the brains of the computer.
