IMPLEMENTATION OF VIRTUAL DESIGN ENVIRONMENT FOR EMBEDDED SYSTEM

The ESDL language and the EHDL language are defined for hardware and software in the virtual design environment for an embedded system. ESDL is a superset of the ANSI C standard, which is enhanced by some data type for embedded programming. EHDL is a kind of hardware description language. The designer can use a co\|verification environment, which consists of embedded software debugger and embedded hardware simulator, to debug the embedded system. With the virtual integration environment, software designers can detect hardware\|related bugs early in the design cycle and hardware designers can obtain a truer picture of system functionality. Both hardware and software errors can be encountered and repaired before the fabrication.
