Loongson Introduces MIPS64 3A2000 & 3B2000 Processors Based on GS464E Architecture

Loongson recently unveiled two new quad core processors Loongson-3A2000 & Loongson-3B2000 targeting respectively consumer electronics and server, and on the company’s new GS464E architecture using MIPS64 cores. Both processors are 4-way superscalar processors built on a 9-stage, super-pipelined architecture with in-order execution units, two floating-point units, a memory management unit, and a crossbar interconnect. According to Imagination Technology, Chinese media reported that 3A2000 CPU was designed at high-performance consumer electronics products such as desktop computers and laptops, 64-bit embedded and DSP applications, and network routers, while 3B2000 will be used in 8 to 16 core server systems, meaning there would be 2 to 4 quad core processors in these servers. I could not find anything about the new processors on Loongson product page, but a white paper describes GS464E architecture in details. Unfortunately, the document is entirely in Chinese, except the abstract and some charts and tables: Loongson GS464E is […]
