), a leading provider of semiconductor solutions differentiated by power, security, reliability and performance, has announced the availability of new advanced motor control algorithms optimized for its SmartFusionA[R] customizable system-on-chip (cSoC), allowing design engineers to realize highly reliable multi-motor control in a single IC and reducing system cost and power. The new solution is ideal for safety-critical applications in industrial, avionics, defense and medical markets.

"Many systems require control of multiple motors which results in a dedicated micro-controller for each individual motor," said Paul Ekas, vice president of marketing for Microsemi's SoC product group. "By implementing these algorithms on SmartFusion devices that combine high-performance hardware acceleration In computing, hardware acceleration is the use of hardware to perform some function faster than is possible in software running on the normal (general purpose) CPU. Examples of hardware acceleration include blitting acceleration functionality in graphics processing units (GPUs) and  with the easy-to-program ARM Cortexacents-M3 microcontroller, designers can significantly reduce power and system complexity."

Microsemi's award-winning SmartFusion cSoC combines three features crucial for successful implementation of advanced motor control algorithms: an embedded ARM Cortex-M3 microcontroller, a high reliability flash-based field programmable gate array See FPGA.  (FPGA (Field Programmable Gate Array) A type of gate array that is programmed in the field rather than in a semiconductor fab. Containing up to hundreds of thousands of gates, there are a variety of FPGA architectures on the market. ) plus integrated programmable analog circuitry for motor sensing. This extensive system integration further reduces overall system complexity and operational cost.

The advanced motor control algorithms address DC brushless, AC brushless and three phase motor control applications. These algorithms have been implemented as a combination of extremely fast and efficient hardware subroutines in the FPGA fabric and embedded software on the ARM Cortex-M3. This high-performance architecture yields significant power reduction benefits and performance improvements by offloading the heavy software processing into dedicated hardware. The reduced processing load on the ARM Cortex-M3 provides more processing headroom to perform key system and application layer control task management.
