MIPS 34K
The MIPS32® 34K™ core family is a revolutionary implementation of the MIPS® MT ASE designed to exploit multi-threading in embedded applications.
Processor derivatives enabled:
The MIPS 34K LinuxLink can also be used as a starting point for Linux development for designs based on the Release 2 of MIPS32 Instruction Set Architecture.
Reference boards/OEM boards enabled:
The MIPS 34K LinuxLink can be used as a starting point for Linux development for designs derived from the Malta board with a MIPS32 34K core from MIPS Technologies.
Notes:
Complete peripheral support for MIPS32 34K family derived integrated processors, or board support for other reference designs, might need to be sourced from manufacturers of the respective processors or reference boards.
Processor Overview
The MIPS32® 34K™ family is a revolutionary implementation of the MIPS® MT ASE designed to exploit multi-threading in embedded applications. Processing multiple software threads in parallel, 34K cores mask the effect of memory latency to deliver significant gains in system performance and cost savings, with a very modest increase in die size. The 34K core family also meets the real-time requirements of embedded applications by giving users the ability to allocate dedicated processing bandwidth to real-time tasks.
