A new floating point and multi media unit has been implemented which provides superior performance for multi-
media and mathematically intensive applications. Finally, SSE2 adds 144 new instructions for double-precision
floating point, SIMD integer, and memory management. Power management capabilities such as AutoHALT, Stop-
Grant, Sleep, and Deep Sleep have been retained. The Streaming SIMD Extensions 2 (SSE2) enable break-through
levels of performance in multimedia applications including 3-D graphics, video decoding/encoding, and speech
recognition. The new packed double-precision floating-point instructions enhance performance for applications that
require greater range and precision, including scientific and engineering applications and advanced 3-D geometry
techniques, such as ray tracing.
The Pentium 4 processor with 512-KB L2 cache on 0.13 micron process Intel Net Burst microarchitecture system
bus utilizes a split-transaction, deferred reply protocol like the Pentium 4 processor. This system bus is not
compatible with the P6 processor family bus. The Intel Net Burst microarchitecture system bus uses Source-
Synchronous Transfer (SST) of address and data to improve performance by transferring data four times per bus
clock (4X data transfer rate, as in AGP 4X). Along with the 4X data bus, the address bus can deliver addresses two
times per bus clock and is referred to as a “double-clocked” or 2X address bus. Working together, the 4X data bus
and 2X address bus provide a data bus bandwidth of up to 4.3 G byte s/second.
Intel will enable support components for the Pentium 4 processor with 512-KB L2 cache on 0.13 micron process
including heat sinks, heat sink retention mechanisms, and sockets. Manufacturability is a high priority; hence,
mechanical assembly can be completed from the top of the motherboard and should not require any special tooling.
The processor system bus uses a variant of GTL+signalling technology called Assisted Gunning Transceiver Logic
(AGTL+) signal technology.
