Enhanced Floating-Point and Multimedia Unit:
The Pentium 4 processor expands the floating-point registers to a full 128-bit and adds an additional register
for data movement which improves performance on both floating-point and multimedia applications.
Internet Streaming SIMD Extensions 2 (SSE2):
With the introduction of SSE2, the NetBurst micro-architecture now extends the SIMD capabilities that
MMX technology and SSE technology delivered by adding 144 new instructions. These instructions include
128-bit SIMD integer arithmetic and 128-bit SIMD double-precision floating-point operations. These new
instructions reduce the overall number of instructions required to execute a particular program task and as a
result can contribute to an overall performance increase. They accelerate a broad range of applications,
including video, speech, and image, photo processing, encryption, financial, engineering and scientific
applications.
Features Used for Test and Performance / Thermal Monitoring:
Built-in Self Test (BIST) provides single stuck-at fault coverage of the micro-code and large logic
arrays, as well as testing of the instruction cache, data cache, Translation Lookaside Buffers (TLBs),
and ROMs.
IEEE 1149.1 Standard Test Access Port and Boundary Scan mechanism enables testing
of the Pentium 4 processor and system connections through a standard interface.
Internal performance counters can be used for performance monitoring and event counting.
Includes a new Thermal Monitor feature that allows motherboards to be cost effectively designed to
expected application power usages rather than theoretical maximums.
