Software Architecture and Engineering

Our software team have extensive experience in the design and programming of a wide range of embedded systems, from microcontroller boards through SoCs and soft processors to set-top boxes, codecs, PVRs and embedded PCs, right through to server programming.

This wide range of expertise makes us ideal for projects that require the development of entire products, from hardware design specified in conjunction with the client and hardware development team through operating systems software and middleware to the implementation of servers that the system communicates with.

Particular areas of expertise or recent experience are listed below.

• Android OS development and porting (with some Android application development experience).
• Extensive Linux expertise, particularly in embedded systems setup and kernel drivers.
• Codec implementation and extensive knowledge of H.264, MPEG-2, MPEG4 part 2, VC-1 / Windows Media 9, AVS, H.263, MP3, AAC, MPEG audio, AC3. Some experience with Theora, Vorbis and VP-8.
• Experience of ARM(v2..v7), ARM Cortex-M3, x86, sh4, Blackfin architectures.
• Specific expertise on ST71xx, TI OMAP3, BF54x . Some expertise on Freescale i.MX35 and i.MX51.
• IPTV technologies and video transports including RTSP, IGMP, HTTP and MMS for video delivery.
• Extensive experience integrating Flash video on embedded devices.
• Linux distributions and the construction of board support packages.
• Significant open source expertise with the Linux kernel, the GNU toolchain (specifically gcc), device drivers and various applications. We have experience of maintenance and upstream patch support for free software packages.
• Coding in C, C++, Java and C# and a range of other languages.
• Windows application and device driver expertise.
• Digital filtering and signal reconstruction.
• Firmware, assembly coding and bring-up of TI 64-series DSPs, Davinci chips, ARM, MIPS, PowerPC, x86, ARC, Microblaze, ST71XX-series SoCs, and a wide range of microcontrollers including Luminary Stellaris, SX-58 and Atmel 89-series chips.
• Networking experience with TCP/IP, ATM, ADSL, X.400. We have worked on X.400/X.500 and RFC822 mail systems and developed IP and ATM stacks.
• Fairly extensive mathematical and theoretical expertise in automata, operating systems, theorem provers, function minimisation, etc.
• Expertise working with international standards (ISO, CCITT, ATM Forum).
• Detailed knowledge of the Windows Media content delivery stack, including Windows Media DRM and MMS.
• Compiler front-end (C, C#, Java) and back-end expertise, specifically a good working knowledge of the GNU toolchain.
• Web applications and web services.
• Extensive Transputer and Occam experience (less useful these days, but somewhat applicable to Tilera-type devices).
