Server Overview

2-3

Additional processor components, such as L1 cache, L2 cache, memory access
crossbar, DDR2 memory controllers, and a JBus I/O interface have been carefully
tuned for optimal performance.

FIGURE 2-2

Motherboard and UltraSPARC T1 Multicore Processor

2.1.2

Performance Enhancements

The server introduces several new technologies with its sun4v architecture and
multithreaded UltraSPARC T1 multicore processor.

Some of these enhancements are:

■

Large page optimization

■

Reduction on TLB misses

■

Optimized block copy

UltraSPARC T1 multicore processor
