processors
- 400 MHz System Bus delivers 3.2 GB of
data per second into and out of the
processor
- Level 1 Execution Trace Cache includes 8
KB data cache, as well as an Execution
Trace Cache that stores up to 12 K decoded
micro-ops in the order of program
execution
- Rapid Execution Engine includes two
Arithmetic Logic Units (ALUs) on the Intel
Pentium 4 processor and are clocked at
twice the core processor frequency
- Level 2 Advanced Transfer Cache (ATC) is
512 KB in size and delivers a much higher
data throughput channel between the Level
2 cache and the processor core. 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
Data clocked into and out of the
cache every clock cycle
- Advanced Dynamic Execution engine is a
very deep, out-of-order speculative
execution engine that keeps the execution
units executing instructions
- Enhanced Floating-point and Multi-media
Unit expands floating-point registers to a
full 128-bit and adds an additional register
for data movement

- Internet Streaming SIMD Extensions 2
(SSE2) adds 144 new instructions that include
128-bit SIMD integer arithmetic and 128-bit
SIMD double-precision floating-point
operations
- Data Prefetch Logic functionality that
anticipates the data needed by an application
and pre-loads it into the Advanced Transfer
Cache, further increasing processor and
application performance
