CoolRISC/FILU50™ Core
CoolRISC/FILU50 is an 8-bit microcontroller with an integrated 16-bit fixed point DSP co-processor core. Xemics and Massana have teamed up to develop and deliver this low power, high performance microcontroller + DSP architecture. This core is available synthesized in Verilog format to ease integration with custom logic on the same silicon. CoolRISC/FILU50 is targeted at ultra low power, low voltage applications such as communication systems, medical and digital hearing aid instruments as well as sensor interface and data processing.
Key Features
- High performance 8-bit microcontroller + DSP extension
- The DSP core has a 16-bit architecture with a 40-bit accumulator
- DSP development and implementation in C
- Scan testable with high test coverage
- Complete development environment

FILU50™ Core
The FILU50™ is an ultra-small 16-bit DSP coprocessor core. At 7000 gates it is much less than ¼ the size of standard DSP cores. Tailored for medium complexity numerical operations, it is optimized for minimum area, bridging the gap between microcontrollers and DSPs. A single memory architecture yields the lowest system cost.
The FILU is capable of implementing various DSP functions which are microcoded and are invoked by a host processor (MCU or RISC) via a shared RAM. The Host has Master control of the RAM via control / status bits. The microcoded kernel includes FIR and IIR filters, FFT, correlation, matrix multiply and Taylor series. Extra DSP functions can be microcoded to suit particular applications. The basic set of microcoded functions are hardwired but RAM based functions can extend the functionality after production.
