Description
The STLS2E02, 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 64bit SIMD and one load/store
unit.
The microarchitecture is organized with nine
stages of pipeline and support of dynamic branch
prediction.
PBGA452
The memory hierarchy is composed by the first
level of 64KB 4-way set associative cache for
instructions and data, the second level of 512KB
unified 4-ways 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.
