Loongson 2F microprocessor
Preliminary Data
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 cache, on-chip 512 Kbyte unified L2 cache On chip DDR2-667 and PCI-X controller 4 W @ 900 MHz power consumption: – Best in class for power management –
Voltage/frequency scaling – Standby mode support – L2 cache disable/enable option Leading edge 90 nm process technology 27x27 heat spreader flip-chip BGA package MIPS based (compatible with MIPSIII) instruction set
HFCBGA452 (27x27x2.9mm)
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, reduc...
