Computer Organization and Design

Computer Organization and Design Computer Organization - ✔️✔️Address issues such as control signals and memory types Computer Architecture - ✔️✔️Focuses on the structure and behavior of the computer system and refers to the logical aspects Principle of Equivalence of Hardware and Software - ✔️✔️Anything that can be done with software can also be done with software, and anything that can be done with hardware can also be done with software. hertz - ✔️✔️cycles per second bus - ✔️✔️group of wires that moves data and instructions to various places within the computer. Moore's Law - ✔️✔️states that the density of silicon chips doubles every 18 months Rock's Law - ✔️✔️states that the cost of capital equipment to build semiconductors will double every four years. semantic gap - ✔️✔️the logical gap that exists between the physical components and a high -
level language virtual machine - ✔️✔️a hypothetical computer Abstract Levels of Modern Computing Systems - ✔️✔️User, High -level Language, Assembly Language, System Software, Machine, Control, Digital Logic control unit - ✔️✔️Part of the CPU that controls execution of instructions, movement of data and timing. Can be hardwired or microprogrammed. von Neumann architecture - ✔️✔️a storied program machine architecture consisting of a CPU, an ALU, registers, and main memory central processing unit (CPU) - ✔️✔️the computer component responsible for fetching instructions, d ecoding them, and performing the indicated sequence of operations on the correct data. Consists of an ALU, registers, and control unit. arithmetric logic unit (ALU) - ✔️✔️the combinational circuit responsible for performing the arithmetic and logic functio ns in a CPU registers - ✔️✔️a hardware circuit that stores binary data main -memory system - ✔️✔️storage where program instructions and data are stored.
