Description

The STLS2F02 is a MIPS based 64-bit

superscalar microprocessor, able to issue four

instructions per clock cycle among six functional

units: two integer, two single/double-precision

floating-point, one 64-bit SIMD and one load/store

unit.

The micro architecture is organized with nine

stages of pipeline and support of dynamic branch

prediction.

The memory hierarchy is composed by the first

level of 64 Kbyte 4-way set associative caches for

instructions and data, the second level of

512 Kbyte unified 4-way set associative cache

and the memory management unit with table

lookside buffer.

The Loongson microprocessor family is the

outcome of a successful collaboration started in

2004 between STMicroelectronics and the

Institute of Computing Technology, part of the

Chinese Academy of Science. Loongson

microprocessors were co-developed by

STMicroelectronics and the Institute of

Computing Technology to address all the

applications requiring high level of performance

and low power dissipation.

Compared to the STLS2E02 processor, the

STLS2F02 has an enhanced architecture

providing higher performances, reduced power

consumption, integrated DDR2 memory controller

and PCI-X bus interface.
