Chapter 4: Processor Technology and Architecture 1. The set of op codes recognized and processed by a CPU is called the CPU's ____________________. 2. The components of an instruction are its op code and one or more ____________________. 3. The contents of a memory location are copied to a register while performing a(n) ____________________ operation. 4. A left ____________________ instruction multiplies a binary numeric value by two. 5. A(n) ____________________ instruction alters the sequence of instruction execution only if a specified condition is true. 6. The use of ____________________ instructions simplifies the process of fetching and decoding those instructions. 7. A(n) ___________________________________ processor does not directly implement instructions that combine data movement and manipulation. 8. A(n) ___________________________________ CPU typically uses variable length instructions and has a large instruction set. 9. The ____________________ time of a processor is 1 divided by the clock rate (in Hz). 10. The address of the next instruction to be fetched by the CPU is held in the ____________________. 11. ____________________ improves CPU performance by dividing instruction execution into stages and overlapping execution of multiple instructions in different stages. 12. ____________________ is a CPU performance enhancement technique in which a CPU guesses whether a branch condition will be true or false based on past experience. 13. The phrase _________________________ describes pipelined instruction execution beyond a conditional branch instruction before the branch condition value is know with certainty. 14. A microchip containing all of the components of a CPU is called a(n) ____________________.
