Instruction Counter (IC)
Program Counter (PC)
The _______ contains the data to be written into memory and receives the data read from memory.
I/O address register
Memory address register
I/O buffer register
Memory buffer register
Instruction processing consists of two steps:
Fetch and execute
Instruction and execute.
Instruction and halt
Fetch and instruction
The _______ routine determines the nature of the interrupt and performs whatever actions are needed.
Interrupt handler
Instruction signal
Program handler
Interrupt signal
The unit of data exchanged between cache and main memory is _____.

Map size
Cache size
Slot size
_______ is more efficient than interrupt-driven or programmed I/O for a multiple-word I/O transfer.
Spatial locality
Direct memory access
Stack access
Temporal locality
The _______ chooses which block to replace when a new block is to be loaded into the cache and the cache already has all slots filled with other blocks.
Memory controller
Mapping function
Write policy
Replacement algorithm
The _______ is a point-to-point link electrical interconnect specification that enables high-speed communications among connected processor chips.
QPI
DDR3
LRUA
ISR
Small, fast memory located between the processor and main memory is called:
Block memory
Cache memory
Direct memory
WORM memory
In a uniprocessor system, multiprogramming increases processor efficiency by:
Taking advantage of time wasted by long wait interrupt handling
Disabling all interrupts except those of highest priority
Eliminating all idle processor cycles
Increasing processor speed
The two basic types of processor registers are:
User-visible and user-invisible registers
Control and user-invisible registers
Control and Status registers
User-visible and Control/Status registers
When an external device becomes ready to be serviced by the processor the device sends a(n) _______ signal to the processor.
Access
Halt
Handler
Interrupt
One mechanism Intel uses to make its caches more effective is _______, in which the hardware examines memory access patterns and attempts to fill the caches speculatively with data that is likely to be requested soon.
Mapping
Handling
Interconnecting
Prefetching
A _______ organization has a number of potential advantages over a uniprocessor organization including performance, availability, incremental growth, and scaling.
Temporal locality
Symmetric multiprocessor
Direct memory access
Processor status word
The processor controls the operation of the computer and performs its data processing fun
True
False
It is not possible for a communications interrupt to occur while a printer interrupt is being processed.
True
False
A system bus transfers data between the computer and its external environment.
True
False
Cache memory is invisible to the OS.
True
False
With interrupts, the processor can not be engaged in executing other instructions while an I/O operation is in progress.
True
False
Digital Signal Processors deal with streaming signals such as audio and video.
True
False
The fetched instruction is loaded into the Program Counter.
True
False
Interrupts are provided primarily as a way to improve processor utilization.
True
False
The interrupt can occur at any time and therefore at any point in the execution of a user program.
True
False
Over the years memory access speed has consistently increased more rapidly than processor speed.
True
False
An SMP can be defined as a stand-alone computer system with two or more similar processors of comparable capability.
True
False
The Program Status Word contains status information in the form of condition codes, which are bits typically set by the programmer as a result of program operation.
True
False
An example of a multicore system is the Intel Core i7.
True
False
In a two-level memory hierarchy the Hit Ratio is defined as the fraction of all memory accesses found in the slower memory.
True
False
The operating system acts as an interface between the computer hardware and the human user.
True
False
