Product design

Design and development services

Network interfaces to suit the client's requirements are configured from our extensive repertoire of logic and software components.

Usually, we work with the client to create a circuit board that includes the appropriate platform (FPGA, memory, and physical interfaces) and we then port the relevant components to that platform.

Logic components include:

MAC layer supporting both Flexilink and legacy Ethernet
network packet forwarding
routing of live streams between audio and video interfaces and the network
routing of packet data between the network and internal software
soft processor optimised for protocol message processing
debug facilities accessed via UDP over Ethernet

Software components are written in a purpose-designed high level language and compiled into code for the soft processor; they include:

SNMP agent
IEC 62379-5-2 signalling
IP-related protocol stacks
updating software in flash memory as specified in IEC62379
fault logging and diagnosis

We have been designing and implementing embedded software and electronic products since 1978, including:

Sinclair ZX range operating software
Multilink and Superlink data network interfaces, both as boxed products and as cards for incorporation into clients' products
FileStore for Multilink networks, also marketed as the AmStore for Amstrad computers: probably the first ever network-attached storage, and with better security and resilience than more commonly-used filing systems
CellStack codecs for video over ATM
Destiny video-over-ATM codes for a major UK CCTV manufacturer

and, of course, the products you will find elsewhere on this website.
