FirmASIC^® Hardware, Firmware and Software

A family of FirmASIC^® hardware platforms is available to address, speedily, the majority of today's communications requirements.

Each individual platform has different embedded sub-systems all with analogue interfaces and an extremely low power requirement.

Using the applied Function Image^™ file loaded to the 'platform', the following applications and combinations of functions can be achieved:

Applications and Functions

Wireless Modem Schemes
- FFSK/MSK, GMSK/GFSK, C4FM, 2FSK, 4FSK, 8FSK and QAM
Coding Systems
- Interleaving and FEC and CRC
Wireline Modem Schemes
- V.32bis, V.32, V.22bis, V.22/Bell 212A, V.23/Bell 202, V.21/Bell 103
Signalling
- Audio band and sub-audio band signalling
- Programmable single or multi-tone, DTMF, call progress tones, CLI, CIDCW, CTCSS, DCS, XTCSS
Audio Processing
- Filtering, gain setting (including VOGAD and AGC) and routing, companding, scrambling, pre/de-emphasis, soft limiting and voice transcoding
Filtering
- A comprehensive range of digitally implemented filters
Signal Measurement
- Threshold detection, averaging, hysteresis
Custom and Auxiliary Functions
- Application specific, user-defined, designed to order functions
- ADCs, DACs, GPIO and synthesised system clocks

The Function Image^™ File
A FirmASIC^® product's on-chip functions and features are configured by the loading of a Function Image^™ file. This is a small data file that is uploaded during device initialisation; this file can be loaded automatically from an external EEPROM or via the host µController over the built-in C‑BUS serial control/data interface.

The device's functions and features may be enhanced by subsequent Function Image^™ releases, facilitating in-the-field upgrades.
The use of such a flexible hardware/firmware/software system means that a single hardware platform can be used to address more than one communication system: a real saving in cost, time and materials.

Function Image^™ files are available from the CML Technical Portal area. This is a resource directory on the CML Microcircuits website (www.cmlmicro.com/) designed to provide files and updates to registered FirmASIC^® product users.
