Internet Streaming SIMD Extensions
Consists of 70 instructions and includes single instruction, multiple data for floating-
point, additional SIMD-integer and cache ability control instructions. Benefits include
higher resolution image viewing and manipulation, high quality audio, MPEG2 video,
and simultaneous MPEG2 encoding and decoding, reduced CPU utilisation for
speech recognition, and higher accuracy and faster response times
L.E.D.
Light Emitting Diode - a light which indicates activity - for example hard disk access.
PCI (Peripheral Component Interconnect)
Developed by Intel, PCI is a local bus standard. A bus is a channel used to transfer
data to (input) and from (output) a computer and to or from a peripheral device. Most
PCs have a PCI bus usually implemented at 32-bits providing a 33 MHz clock speed
with a throughput rate of 133 MBps.
NetBurst® micro-architecture (Intel NetBurst® micro-architecture)
The NetBurst® micro-architecture delivers a number of new and innovative features
including Hyper Pipelined Technology, 400 MHz System Bus, Execution Trace
Cache, and Rapid Execution Engine. It also delivers a number of enhanced features,
including Advanced Transfer Cache, Advanced Dynamic Execution, Enhanced
Floating Point and Multimedia Unit, and Streaming SIMD Extensions 2. Intel
NetBurst® Microarchitecture provides higher throughput within the processor and out
to memory and I/O for improved headroom.
PCI
Peripheral Component Interface. It became apparent to manufacturers that the
8MHz AT ISA BUS on the standard PC was just not fast enough for today's
applications, and so PCI was invented. It is a high speed data bus that carries
information to and from components - known as 'Local Bus'.
PCI-X
The 64-bit PCI-X interface (PCI-X 1.0a) can be operated at 133 MHz, (or at 100 MHz
and 66 MHz) which achieves a greater than two-fold boost in performance over PCI
2.2 bus technology. The 133 MHz PCI-X interface achieves up to 1 GB/s throughput,
a two-fold increase over 66 MHz PCI 2.2.
PCI-Express
PCI Express is a 3rd generation I/O architecture where ISA and PCI were
respectively the 1st and 2nd generations. A high-speed, general-purpose serial I/O
interconnect, PCI Express will initially offers speeds of 2.5 Gigabits per second,
support multiple widths ("lanes" of data that range from 1 to 32), and scale to the
limits of copper. PCI Express will unify I/O architecture for desktop, mobile, server,
communications platforms, workstations and embedded devices while also
coexisting with PCI and USB connection types
