buffer
(foldoc) | buffer
1. An area of memory used for storing messages. Typically, a
buffer will have other attributes such as an input pointer
(where new data will be written into the buffer), and output
pointer (where the next item will be read from) and/or a count
of the space used or free. Buffers are used to decouple
processes so that the reader and writer may operate at
different speeds or on different sized blocks of data.
There are many different algorithms for using buffers, e.g.
first-in first-out (FIFO or shelf), last-in first-out (LIFO or
stack), double buffering (allowing one buffer to be read while
the other is being written), cyclic buffer (reading or writing
past the end wraps around to the beginning).
2. An electronic device to provide compatibility between two
signals, e.g. changing voltage levels or current capability.

buffer overflow
(foldoc) | buffer overflow
buffer overrun
What happens when you try to store more data in
a buffer than it can handle. This may be due to a mismatch
in the processing rates of the producing and consuming
processes (see overrun and firehose syndrome), or because
the buffer is simply too small to hold all the data that must
accumulate before a piece of it can be processed. For
example, in a text-processing tool that crunches a line at a
time, a short line buffer can result in lossage as input
from a long line overflows the buffer and overwrites data
beyond it. Good defensive programming would check for
overflow on each character and stop accepting data when the
buffer is full.

buffered write-through
(foldoc) | buffered write-through
write buffer
A variation of write-through where the
cache uses a "write buffer" to hold data being written back
to main memory. This frees the cache to service read
requests while the write is taking place. There is usually
only one stage of buffering so subsequent writes must wait
until the first is complete. Most accesses are reads so
buffered write-through is only useful for very slow main
memory.

circular buffer
(foldoc) | circular buffer
An area of memory used to store a continuous
stream of data by starting again at the beginning of the
buffer after reaching the end. A circular buffer is usually
written by one process and read by another. Separate read and
write pointers are maintained. These are not allowed to
pass each other otherwise either unread data would be
overwritten or invalid data would be read.
A circuit may implement a hardware circular buffer.

frame buffer
(foldoc) | frame buffer
Part of a video system in which an image is
stored, pixel by pixel and which is used to refresh a
raster image. The term "video memory" suggests a fairly
static display whereas a frame buffer holds one frame from a
sequence of frames forming a moving image.
Frame buffers are found in frame grabbers and {time base
correction} systems, for example.

hardware circular buffer
(foldoc) | hardware circular buffer
digital signal processors which
support hardware circular buffers automatically generate and
increment pointers for memory accesses which wrap to the
beginning of the buffer when its end is reached, thus saving
the time and instructions otherwise needed to ensure that the
address pointer stays within the boundary of the buffer, and
speeding the execution of repetitive DSP algorithms.

jump trace buffer
(foldoc) | jump trace buffer
JTB
(JTB) A feature of some pipelined processors (e.g. Amulet,
Pentium?) which stores the source and destination addresses
of the last few branch instuctions executed. When a branch
instruction is fetched, its source is looked for in the JTB.
If found, the next instuction fetch will be from the previous
destination of that branch. If it turns out that the branch
shouldn't have been taken this time, then the pipeline is
flushed. This means that in a tight loop it is not
necessary to flush the pipeline every time you jump back to
the start.

OBOE
(OBOE) A tool by R. Banfi,
D. Bruschi, and E. Rosti for the automatic detection of
buffer overflow vulnerabilities in object code. OBOE
can be applied to operating system components as well as
ordinary application programs. It was designed for the
system administrator to identify vulnerable programs before
they are exploited. Being automatic, OBOE can be run as a
background process for the analysis of all potentially
insecure programs installed on a Unix system. It runs on
HP-UX, Linux, and Sun Solaris.

translation look-aside buffer
(foldoc) | Translation Look-aside Buffer
TLB
(TLB) A table used in a {virtual
memory} system, that lists the physical address page
number associated with each virtual address page number.
A TLB is used in conjunction with a cache whose tags are
based on virtual addresses. The virtual address is presented
simultaneously to the TLB and to the cache so that cache
access and the virtual-to-physical address translation can
proceed in parallel (the translation is done "on the side").
If the requested address is not cached then the physical
address is used to locate the data in main memory. The
alternative would be to place the translation table between
the cache and main memory so that it will only be activated
once there was a cache miss.

z-buffer
(foldoc) | Z-buffer
An array used to store the maximum Z coordinate
of any feature plotted at a given (X, Y) location on the
screen, used for hidden line removal in a 2D rendering of a
3D scene. The Z axis is perpendicular to the screen with
values increasing toward the viewer so that any point whose Z
coordinate is less than the corresponding Z-buffer value will
be hidden behind some feature which has already been plotted.

buffer overflow
(jargon) | buffer overflow
n.
What happens when you try to stuff more data into a buffer (holding area)
than it can handle. This problem is commonly exploited by crackers to get
arbitrary commands executed by a program running with root permissions.
This may be due to a mismatch in the processing rates of the producing and
consuming processes (see overrun and firehose syndrome), or because the
buffer is simply too small to hold all the data that must accumulate before
a piece of it can be processed. For example, in a text-processing tool that
crunches a line at a time, a short line buffer can result in lossage as
input from a long line overflows the buffer and trashes data beyond it.
Good defensive programming would check for overflow on each character and
stop accepting data when the buffer is full up. The term is used of and by
humans in a metaphorical sense. “What time did I agree to meet you? My
buffer must have overflowed.” Or “If I answer that phone my buffer is going
to overflow.” See also spam, overrun screw.
