CML’s proprietary FirmASIC® component technology reduces cost, time to market and development risk, with increased
flexibility for the designer and end application. FirmASIC® combines Analogue, Digital, Firmware and Memory
technologies in a single silicon platform that can be focused to deliver the right feature mix, performance and price for
a target application family. Specific functions of a FirmASIC® device are determined by uploading its Function Image™
during device initialization. New Function Images™ may be later provided to supplement and enhance device
functions, expanding or modifying end-product features without the need for expensive and time-consuming design changes. FirmASIC® devices provide
significant time to market and commercial benefits over Custom ASIC, Structured ASIC, FPGA and DSP solutions. They may also be exclusively customised
where security or intellectual property issues prevent the use of Application Specific Standard Products (ASSP’s).
