Actel combines analog with flash memory and FPGA fabric

7 September 2005 Programmable Logic

Actel has unveiled its Fusion technology, which it has billed as the era of the programmable system chip (PSC), designed to bring true programmability to mixed-signal solutions.

The Actel Fusion technology integrates mixed-signal analog capabilities with flash memory and FPGA fabric in a monolithic PSC. The company says the technology brings the benefits of programmable logic to application areas that until now have only been served by discrete analog component and mixed-signal ASIC suppliers.

The new technology takes advantage of the properties of Actel's flash-based FPGAs, including a high-isolation, triple-well process and the ability to support high-voltage transistors. In addition, when used in conjunction with Actel's ARM7 and 8051-based soft MCU cores, Fusion technology represents an exemplary PSC platform.

The Fusion technology will enable designers to design at both very high and very low levels of abstraction, it says. Fusion peripherals include hard analog IP and hard and/or soft digital IP. Peripherals will communicate across the FPGA fabric via a layer of soft gates at the Fusion backbone. Much more than a bus interface, the Fusion backbone integrates a micro-sequencer within the FPGA fabric and will configure the individual peripherals and support low-level processing of peripheral data.

It also gives designers high levels of flexibility by allowing them to easily reconfigure analog block settings to perform widely different functions by simply downloading data from embedded flash memory.

To support Fusion technology, Actel is developing a series of tools to help maximise designer productivity. The tools suite, implemented as extensions to Actel's Libero integrated design environment, will add a comprehensive hardware/software debug capability as well as a suite of utilities to simplify development of embedded soft ARM and 8051 processor-based solutions.
