MIPS 4K
The 4K family cores can be implemented with off-the-shelf cell libraries and memories and instruction and data caches can be configured to meet application requirements.
Processor derivatives enabled:
The MIPS 4K LinuxLink can also be used as a starting point for Linux development for designs based on the Release 1 of MIPS32 Instruction Set Architecture.
Reference boards/OEM boards enabled:
The MIPS 4K LinuxLink can be used as a starting point for Linux development for designs derived from:
Notes:
Complete peripheral support for MIPS32 4K 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.
