frame buffering - THE CORRECT ANSWER-A portion of RAM
containing a bitmap that drives a video display. It is a memory
buffer containing a complete frame of data.
The image to be represented onscreen is stored in the frame
buffer, and the bit pattern per pixel is read out to the graphics
display at the refresh rate. The animation below shows a frame
buffer with a simplified design of just 4 bits per pixel.
Datapath - THE CORRECT ANSWER-The component of the processor
that performs arithmetic operations
Control - THE CORRECT ANSWER-The component of the processor
that commands the datapath, memory, and I/O devices
according to the instructions of the program.
,Integrated circuit - THE CORRECT ANSWER-Also called a chip. A
device combining dozens to millions of transistors.
Central processor unit (CPU) - THE CORRECT ANSWER-Also called
processor. The active part of the computer, which contains the
datapath and control and which adds numbers, tests numbers,
signals I/O devices to activate, and so on.
Static random access memory (SRAM) - THE CORRECT ANSWER-Also
memory built as an integrated circuit, but faster and less dense
than DRAM.
Instruction set architecture - THE CORRECT ANSWER-Also called
architecture. An abstract interface between the hardware and
the lowest-level software that encompasses all the information
necessary to write a machine language program that will run
correctly, including instructions, registers, memory access, I/O,
and so on.
Application binary interface (ABI) - THE CORRECT ANSWER-The user
portion of the instruction set plus the operating system
interfaces used by application programmers. It defines a
standard for binary portability across computers.
Volatile memory - THE CORRECT ANSWER-Storage, such as DRAM,
that retains data only if it is receiving power.
Nonvolatile Memory - THE CORRECT ANSWER-A form of memory that
retains data even in the absence of a power source and that is
,used to store programs between runs. A DVD disk is
nonvolatile.
Magnetic disk - THE CORRECT ANSWER-Also called hard disk. A form
of nonvolatile secondary memory composed of rotating platters
coated with a magnetic recording material. Because they are
rotating mechanical devices, access times are about 5 to 20
milliseconds and cost per gigabyte in 2012 was $0.05 to $0.10
Main memory - THE CORRECT ANSWER-Also called primary memory.
Memory used to hold programs while they are running;
typically consists of DRAM in today's computers.
Secondary memory - THE CORRECT ANSWER-Nonvolatile memory
used to store programs and data between runs; typically
consists of flash memory in PMDs and magnetic disks in
servers.
Flash memory - THE CORRECT ANSWER-A nonvolatile semiconductor
memory. It is cheaper and slower than DRAM but more
expensive per bit and faster than magnetic disks. Access times
are about 5 to 50 microseconds and cost per gigabyte in 2012
was $0.75 to $1.00.
Single Instruction Single Data (SISD) - THE CORRECT ANSWER-A
uniprocessor
Multiple Instruction Multiple Data (MIMD) - THE CORRECT ANSWER-
A multiprocessor.
, Single Program, Multiple Data Streams (SPMD) - THE CORRECT
ANSWER-The conventional MIMD programming model, where a
single program runs across all processors.
Single Instruction Stream, Multiple Data Streams (SIMD) - THE
CORRECT ANSWER-The same instruction is applied to many data
streams, as in a vector processor.
Data-level parallelism - THE CORRECT ANSWER-Parallelism achieved
by performing the same operation on independent data
vector-based code - THE CORRECT ANSWER-
conventional code - THE CORRECT ANSWER-
LEGv8 - THE CORRECT ANSWER-assembly instructions
multimedia extensions (MMX) - THE CORRECT ANSWER-An
expanded set of instructions supported by a processor that
provides multimedia-specific functions.
data hazard (pipeline data hazard) - THE CORRECT ANSWER-When a
planned instruction cannot execute in the proper clock cycle
because data that is needed to execute the instruction are not
yet available.
forwarding (bypassing) - THE CORRECT ANSWER-A method of
resolving a data hazard by retrieving the missing data element
