                 Q5: What DSP operating systems are available?

   [Researched and written by Chuck Corley chuckc@sr.hp.com. Last updated
   11/22/96]

           Some designers need to use an operating system with a DSP
           processor and others don't. The need for DSP operating system
           seems to depend on the task(s) to be performed.

           For simple DSP tasks where a single function or a few simple
           functions are being performed, an operating system is usually not
           needed and could get in the way.

           When the number and complexity of DSP tasks increase, an operating
           system of some type may be needed in order to allocate system
           resources (RAM, etc.) and to perform multi-tasking, where several
           tasks take turns executing.

           Some people have chosen to write their own DSP 'task-switching' or
           'job allocating' operating system. Whether this is the right
           choice for you depends on how involved your operating system needs
           to be, and how much time you have available to spend writing it.

           Many companies offer pre-written operating systems that execute on
           DSP processors. In exchange for your money they offer to save you
           the time and effort of writing and debugging your own 'operating
           system' or 'task switcher'.

           These companies describe their products as 'real-time' operating
           systems. What 'real-time' means can be debated, but it normally
           means that the maximum time for the operating system to respond to
           an external event is known. The calculation for measuring this
           time involves adding together interrupt response time, task
           switching time, and other processor and operating system
           benchmarks. 'Real-time' also usually means 'fast'. Embedded CPU or
           DSP tasks often require a 'real-time' response time.

           Prices and features vary. Most companies charge for purchasing
           their 'development environment', which allows you to develop code
           which will run on their operating system. Some companies also
           charge a fee for each product you build that includes their
           operating system software. This is usually called a 'target fee'
           or 'runtime license' fee. Some operating systems have no 'runtime
           license' fees.

           It is *very* important to negotiate what the runtime license fee
           will be *in advance*. This is not nearly as big a problem as it
           used to be, but be careful! If this runtime license fee is not
           agreed upon in writing when the development system is purchased,
           you could be in a bad position later. You will have invested a lot
           of time and effort writing software to work with a particular
           operating system, and when your creation is produced you could
           discover that the 'runtime license fee' has increased or is more
           than you can afford. Considering the amount of work you would have
           invested in that operating system, you would be in a very poor
           bargaining position.

           You will also need to decide if having the source code for the
           operating system is important to you. Some companies include it
           for free, while others may charge extra.

           Features for the DSP operating systems are listed below. Some
           vendors claim that a 'No' listing for a feature doesn't
           necessarily mean that their operating system is missing something
           you need. Many companies state that particular features were not
           appropriate for either a 'DSP' or a 'real-time' operating system,
           and so they did not implement them. Other companies stated that
           some features were not appropriate for their targeted users.

           One suggestion for comparing features: Make a list of the features
           you *really* need and compare it against the list below.
