Embedded Coder creates code efficient enough for use in embedded systems. Embedded techniques are embedded in, and specific to, a model. Its core library, libfreeswitch, can be embedded into other projects. Flash Video content may also be embedded within SWF files. OpenMath data can be embedded in MathML using the element. It comprises a database specifically targeted for embedded and smaller-scale applications. When needed, JavaScript can also be embedded directly into Java code, using Java comments. AMD builds graphic processors for use in embedded systems. Sensors can be embedded in microLED displays. Extensible Metadata Platform can also be embedded in JPEG 2000. It also includes support for debugging and embedded Git Control. For example, there are tools for modeling and designing logic for embedded controllers. Many transportation systems from flight to automobiles use embedded systems extensively. CAB files are also sometimes embedded into other files. Optionally an uncompressed thumbnail can be embedded.
