 Tensilica 
Short Desc. : Xtensa LX3
Overview :
Tensilica's Xtensa LX3 DPU (dataplane processing unit) was designed from the start to be a basic building block in SOC designs. It is ideal for handling complex compute-intensive DSP applications where an RTL implementation may be the only other option. Xtensa LX3 DPUs are configurable and extensible to meet application requirements exactly.
Features : - Backwards-compatible ISA since 1999

- Fundamentally architected for extensibility
- Base instruction set of 80 instructions
- All optional blocks are still available
- Any differentiating designer-defined instructions written in 1999 can be re-used today

- Optional pre-defined execution units

- 32-bit multiplier and/or 16-bit multiplier and MAC
- ConnX Vectra LX DSP engine with 4-way SIMD and one or two Load/Store units
- ConnX D2 DSP engine
- ConnX Baseband engine
- HiFi 2 Audio engine
- Single-precision floating point unit
- Double-precision floating point acceleration

- Differentiate with designer-defined instructions

- Make your specific algorithm run even more efficiently by adding the instructions it needs
- Development tools automatically adapt for full support
