MIPS32™ 4Kc® Hard IP Core
The MIPS32™ 4Kc™ Hard Core is a technology-specific implementationof the synthesizable 32-bit MIPS32 4Kc core. The implementation is targeted forthe SMIC 0.18um process. Chip developers or system OEMs who are building complexSystem-On-Chip ASIC devices can significantly reduce design time, resources,and time-to-market by using the 4Kc SMIC Hard Core.- MIPS32® 4Kc® hard IP core offers performance of 190 MHz and allows designers to significantly reduce design time, efficiently use resources, and quickly get to market.
- Based on MIPS32 architecture for high performance.
- 8KB Instruction and 8KB Data cache
- TLB and register files arrays reduce power consumption without reducing application performance.
- Enhanced JTAG (EJTAG) debug with trace and fast download enable quick and easy debugging.
- Testability features include BIST and full scan
- All major operating systems and compiler tool chains, and hundreds of third-party development tools, support the MIPS architecture.
