M4K™ Hard IP Cores
The MIPS32® M4K® Hard IP Cores are technology-specificimplementations of the synthesizable 32-bit MIPS32 M4K core. Available implementationsinclude area optimized and performance optimized cores targeting SMIC 0.18µm.Chip developers or system OEMs who are building complex System-On-Chip (SoC)ASIC devices can significantly reduce design time, resources, and time to-marketby using M4K Hard IP Cores. The target markets for these cores include Microcontrollers,Automotive, Cell phones.- Hard IP cores allow designers to significantly reduce design time, efficiently use resources, and quickly get to market
- Based on MIPS32 architecture for high performance
- Extensive clock gating reduces power consumption without reducing application performance
- Enhanced JTAG (EJTAG) debug with trace and fast download enable quick and easy debugging
- All major operating systems and compiler tool chains, and hundreds of third-party development tools, support the MIPS architecture
- Testability features include BIST and full scan
- Supports CorExtend capability which enables users to significantly enhance the value and competitive advantage of their SoC products
