CPEN 4700 - Final Exam (Answered) 100%
Harvard Architecture
A type of computer system design in which the CPU uses separate memory interfaces
for accessing instructions and data operands
Index
The portion of a memory address that determine where in cache (in what line) a given
main memory address can be mapped
MMU
A hardware device that handles the details of address translation in a system with
virtual memory
Key Register
In an associative memory, this determines the bit positions where matching is significant
Ease of Use
An architectural quality attribute that reflects how well a given instruction set
architecture supports systems programming
SAM
This memory organization has variable access time and uses a relative address to
locate the next item to be read or written
Dirty Bit
This is used to indicate that a cache line has been modified since it was loaded from
main memory
Benchmark
A program(s) that are used to compare the performance of various computer systems
Segment Fault
This happens when a location within a variable-sized region of a program's logical
memory is referenced, but it is not currently mapped to a location in physical main
memory
TLB
A type of cache used to hold virtual-to-physical address translation information
Transistor
This technological development was an important factor in moving from "first-
generation" to "second-generation" computers
Valid Bit
This is used to indicate that a cache line has been properly initialized from main
memory
This early computer used the stored program concept; its logical design was
described in a 1945 report written by John von Neumann
EDVAC
A computer that used (or will use) an 8-bit microprocessor as its main CPU would
most likely have a manufacture date of:
1981
A computer that use (or will use) ferrite core technology in its main memory
system would most likely have a manufacture date of:
1965

bottleneck" using which of these approaches?
Separate memories for instructions and data
Which of the following is NOT part of the von Neumann execution cycle as
discussed in class?
Decode operand register
Which of the following would be best suited as a benchmark for applications that
work mainly on integer values that are not elements of vectors or arrays?
Dhrystones
Which of the following cache mapping strategies would be likely to achieve the
highest hit ratio given the same program and data set?
Fully associative
The functionality provided in hardware by a content-addressable memory is most
similar to which of the following software concepts?
A database query
Which of the following cache implementation techniques would keep the contents
of main memory synchronized with the contents of the cache?
Write-Through
Which of these virtual memory techniques uses a table(s) to map the addresses
of fixed-size regions of memory
Paging and Segmentation & Paging
Which of these virtual memory techniques uses a table(s) to map the address of
variable-size regions of memory?
Segmentation and Segmentation & Paging
The first computer sold commercially. Approximately 46 of these machines were
sold to the U.S. Census Bureau for data processing
UNIVAC 1
A machine that debuted during the third generation of computing; it has been
described as the world's first supercomputer
CDC 6600
The performance of the DEC VAX 11/780 computer was approximately how many
MIPS?
1 MIPS
A computer with a CPU clock cycle time of 1.25 ns runs at how many MHz?
800 MHz
The _______ ___________ of a storage device refers to the amount of information
that can be stored in a given physical space or volume
