XBurst Embeded CPUs

The XBurst CPU architecture is compatible with MIPSII

MIPS architecture

MIPS is a reduced instruction set computer instruction set architecture developed by MIPS Technologies . The early MIPS architectures were 32-bit, and later versions were 64-bit...

 and has a 8-staged pipeline.
XBurst CPU technology consists of 2 parts:

• A RISC/SIMD/DSP hybrid instruction set architecture which enables the processor to have the capability of computation, signal processing and video processing.
• An innovative pipeline engine which consumes very little power while emitting instructions. The processor core (including L1 cache) consumes 100mw at 1000MHz at a 65nm LP process.
