Modulated signals are often scrambled when they are modulated. ![]() If you have found this solution useful then please do hit the Google (+1) button so that others may be able to find it as well. When the complexity issue is coupled with the fact that the majority of DSP algorithms are block oriented vector processing algorithms and it is now becoming possible for high level language compilers to produce code that is 100% optimised. This means that it is increasingly difficult for programmers to learn how to fully optimise their algorithms. The architectures of the latest DSPs are also becoming more complex, for example with the integration of parallel execution units. Modern high performance DSPs are also changing the way we view algorithmic efficiency and an increasing number of projects are written in a high level language because the savings at development time are far greater than the extra cost overhead of using faster processors at deployment. Using the same language for development and deployment often allows the same code to be used for both, with the different I/O requirements handled through the use of conditional compilation of the source. An increasingly common development route is to develop the algorithms on a PC or Workstation and then rewrite the application for the target processor. The development process is therefore very much easier than writing the algorithm in assembly code from scratch. The latest generation of compilers allows high level code to be compiled to a quality of assembly code that is very close to that which would be generated by hand. Integration with real-time kernels and operating systems.Rapid prototyping and algorithm proving.Primary Reasons For Using High Level Languages Another benefit to using a high level language for the system development is that a system can be rapidly prototyped to prove the algorithms and then hand optimised using assembly code for the time critical areas. Today's commercial pressures have moved the "goal-posts" dramatically and typical project development timescales require a larger part of the application to be developed using a high level language. Crosshair shows the pixel coordinates of the cursor on the monitor.The field of Digital Signal Processing is constantly pushing the price / performance envelope of technology and traditionally this has required systems developers to use assembly language for the majority of the time critical signal processing routines.Frames of to custom sizes can shown on-screen.Guides are vertical and horizontal guide lines displayed over the screen to be used as guides.Loupe is an adjustable magnifying glass that shows the specific pixel color under the mouse.Screens overlays common screen resolutions along with the area of webpages visible to common browsers within those resolutions.Rulers measuring pixel size in both X and Y dimensions are shown over the screen and can be rotated 360 degrees.Dimensions show the pixel size (for both X and Y dimensions) of any object within a color range under the mouse.The idea behind the program is that designers can check the size of their work against real-world computer display measurements and be able to measure their work as well. XScope is a utility by The Iconfactory & ARTIS Software that can measure any element displayed on screen.
