Loongson 2F:

High performance 64-bit superscalar MIPS^®microprocessor

Preliminary Data

Features

■ 64-bit superscalar architecture

■ 900 MHz clock frequency

■ Single/double precision floating-point units

■ New streaming multimedia instruction set

support (SIMD)

■ 64 Kbyte instruction cache, 64 Kbyte data

HFCBGA452 (27x27x2.9mm)

cache, on-chip 512 Kbyte unified L2 cache

■ On chip DDR2-667 and PCI-X controller

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 (MMU) with

translation lookaside buffer (TLB).

■ 4 W @ 900 MHz power consumption:

– Best in class for power management

– Voltage/frequency scaling

– Stand-by mode support

– L2 cache disable/enable option

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.

■ Leading edge 90 nm process technology

■ 27x27 heat spreader flip-chip BGA package

■ MIPS based instruction set (MIPS III

compatible)

Description

The STLS2F01 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.

Compared to the STLS2E02 processor, the

STLS2F01 has an enhanced architecture

providing higher performance, reduced power

consumption, integrated DDR2 memory controller

and PCI-X bus interface.

The micro architecture is organized with nine-

stage of pipeline and support of dynamic branch

prediction.
