Intel® Pentium® III Processor,
256 KB, Level 2 Advanced Transfer Cache
The Advanced Transfer Cache (ATC) consists of microarchitectural improvements to
provide a higher data bandwidth interface between the level 2 cache and the processor
core that is completely scaleable with the processor core frequency. Features of the ATC
include:
•
Non-Blocking, full speed, on-die level 2 cache
•
8-way set associativity
•
256-bit data bus to the level 2 cache
•
Reduced latency interface to cache data (as compared to discrete caches)
Advanced System Buffering
The Advanced System Buffering consists of optimizations in the system bus buffer sizes
and bus queue entries that result in an increase in the utilization of the available
bandwidth on the 100 and 133 MHz system bus.
•
4 writeback buffers
•
6 fill buffers
•
8 bus queue entries
Internet Streaming SIMD Extensions:
The Internet Streaming SIMD Extensions consist of 70 new instructions and includes
single instruction, multiple data for floating-point, additional SIMD-integer and
cacheability control instructions. Some of the benefits to desktop and Internet
applications of Internet Streaming SIMD Extensions include:
•
Higher resolution and quality images can be viewed and manipulated than previously
possible
•
High quality audio, MPEG2 video, and simultaneous MPEG2 encoding and
decoding
•
Reduced CPU utilization for speech recognition, as well as higher accuracy and
faster response times
System Bus
•
The system bus runs at 133 MHz (available on versions denoted with the letter B) allowing for a 33%
increase in available bandwidth to the processor (over 100 MHz system bus)
•
The system bus supports multiple outstanding transactions to increase bandwidth availability
Intel Processor Serial Number:
The Intel® processor serial number provides for improved levels of asset management,
platform identification and information management.
