     20'''SH4'''
    2121
     22TitanNit was first established on the SH4 (Super-H) chipset for the atemio and kathrin receivers.
    2223
    23 Currently the only supported architecture is the Super-H (sh4), the chipset is a biendian 32bit RISC chipset originally developed for multimedia devices, gaming consoles and set top boxes and was used in the Sega's Dreamcast.
    24 it has prooved popular because of its low cost and high proformance and has found use in many low power embedded devices because of it low power consumption.
     24The Super-H (SH4) chipset is a biendian 32bit RISC Superscaler chipset, this chipset is aimed at increacing throughput by using called instruction-level parallelism within a single core.
    2525
    26 Titannit is linux based and is based on ST micro electronics opensource linux project made for the Super-H chipset called ([http://stlinux.com/ STLinux]).
     26Originally developed for multimedia devices, gaming consoles and set top boxes and was used in the Sega's Dreamcast.
     27it has prooved popular because of its low cost and high proformance, it has found use in many low power embedded devices.
    2728
    28 The sh4 chipset has been popular with the satellite community because of the quality of the display output and the open source nature of the linux system that runs on it, since its introduction has had many third party firmwares developed for it from different development teams.
     29Titannit SH4 is a linux based and is based on ST micro electronics opensource linux project made for the Super-H chipset called ([http://stlinux.com/ STLinux]).
     30
     31The SH4 chipset has been popular with the satellite community because of the quality of the display output due to inclusion of a high class floating point math unit and high speed bus which is the key components used for drawing graphics, the open source nature of the linux system that runs on it, since its introduction it has had many third party firmwares developed for it from different development teams.
    2932
    3033TitanNit is Team AAF's sucessor to the AAF enigma 2 based firmware, aaf enigma is not currently developed and support has ended to futher develop TitanNit we reccomend that if current AAF Enigma users update to TitanNit for future support.
    3134
    32 Note: There is a possibility that development may spread to other Receiver models and other architectures such as the Proadcom MIPS architecture.  Future development to support more Receivers is at the mercy of the developers and also the Hardware manufacturers.

     36
     37'''Mips'''
     38
     39After the sucess with TitanNit on the SH4 chipset the developers then started development on the Mips chipset for use with the newly introduced Atemio 5000 series receivers.
     40
     41The Mips chipset (Microprocessor without Interlocked Pipeline Stages) is a biendian 32bit RISC chipset, this chipset is aimed at increacing throughput by using deep instruction piplines combined with single cycle instruction processing.
     42
     43Originally developed for the embedded market it has found use in consumer products gaming consoles and set top boxes and was used in the Nintendo 64 and three Sony Playstation products.
     44
     45The chipset has prooved popular in the STB market because of the inclusion in the Dreambox Recievers that has spawned clone and copy cat receivers, but it has a draw back that it lacks finness in the picture quality department over the SH4 based receivers as explained above, it has the advantage that it has a larger user base and therfore more plugins are available currently than the sh4 chipset based recievers.
     46
     47Titannit Mips is a linux based and is based on the open source project [https://github.com/oe-alliance oe-alliance].
     48
     49The Mips chipset has been popular with the satellite community because of open source nature of the dbox based firmwares since its introduction has had many third party firmwares developed for it from different development teams.

     52
     53'''Future Architectures'''
     54
     55There is a possibility that development may spread to other Receiver models and other architectures in the future such as the ARM architecture or PPC.
     56Future development to support more Receivers is at the mercy of the developers and also the Hardware manufacturers who support the TitanNit project.

    4264For performance reasons we have opted to use C programming language [http://en.wikipedia.org/wiki/C_(programming_language) wiki]
     
    4567Python is a higher level scripting language used to define and setup elements in the gui and for an intrim language between the OS that is easily programmable.
    4668This was done so that users can easily develop and manipulate the system and integrate plugins skins etc... into the system but this has a performance hit on these system and can cause them to become slow and laggy and bloated but has the benifit of being easy for the community to develop for with out knowing much about the underlying system.
     69
     70The problem with this system has been that python has become so ingrained into the system and gui and often is now beyond the capibilities for the average user it was intended to used by not to mention it is a semi complicated language to learn to start with.
    4771
    4872TitanNit adresses these key conserns and has developed as much as possible br programming in C to increase the performance of the system but still alowing ease of intergration of plugins and skins using basic scripts.

    7293The TitanNit project is proudly produced by the AAF Dev team and other loyal members and helpers.
    7394development is important aswell as the work they do to help out with such things as skin's, channel logo's and setups, translations, supplemental programs and tools, and plugins and this is a place for them to be recognized.
