The STLS is a family of 64-bit, superscalar, low power processor designed to address all applications requiring high level of performance and reduced power consumption.
The STLS processors are based on the Loongson2E core technology, licensed by the Institute of Computing Technology (ICT), part of the Chinese Academy of Science. The STLS processor family is the outcome of a successful collaboration begun in 2004 between ST and ICT.
The STLS processors maximize the performance per dollar and per watt, and are therefore the perfect choice for price- and power-sensitive computers, thin clients, web appliances and home media center devices.
These processors provide the versatility of the Linux operating system (OS), a reliable and secure open-source OS that greatly reduces system cost. The instruction set is based on MIPS®, a 64-bit RISC architecture richly supported by software development tools.

Description |
| STLS2F01 |
900 MHz 64-bit superscalar MIPS based microprocessor |
|
| |
| Applications |
The processor is suitable for all applications that require high-level performance and low power dissipation such as affordable though powerful computers.
The STLS family delivers the performance of commonly used desktop and notebook microprocessors with higher efficiency, lower power consumption and reduced costs.
These features also make the Loongson processor family ideal for server client applications in public administrations, small and mid-size businesses, interactive kiosks, school computing labs and internet cafes.
In addition, the Loongson processor benefits form the MIPS technology ecosystem, which is recognized by the silicon design community as one of the best environments for embedded computer systems and consumer applications.
