Chip-Multitheaded (CMT) Multicore
Processor and Memory Technology
The UltraSPARC ® T1 multicore processor is the basis of the Sun Fire T1000 server.
The UltraSPARC T1 processor is based on chip multithreading (CMT) technology
that is optimized for highly threaded transactional processing. The UltraSPARC T1
processor improves throughput while using less power and dissipating less heat
than conventional processor designs.
Depending on the model purchased, the processor has six or eight UltraSPARC
cores. Each core equates to a 64-bit execution pipeline capable of running four
threads. The result is that the 8-core processor handles up to 32 active threads
concurrently.
Additional processor components, such the DDR2 memory controllers, L1 cache, L2
cache, and the Jbus I/O interface have been carefully tuned for optimal
performance.
