This paper presents a low-power asynchronous implementation of the 80C51 microcontroller. It was realized in a 0.5 µ m CMOS process and it shows a power advantage of a factor 4 compared to a recent synchronous implementation in the same technology. The chip is fully bit compatible with the synchronous implementation, and timing compatible for external memory access. The circuit is a compiled VLSI-program, using Tangram as VLSI-programming language and the Tangram tool set to compile the design automatically to a standard-cell netlist. This design approach proves to be powerful enough to describe the microcontroller and derive an efficient implementation. Further, it offers the designer the possibility to explore various alternatives in the design space.
IDE開發環境，可以掛載SDCC
The BASIC IDE is a new, RAD (Rapid Application Development) IDE (Integrated Development Environment) for the RapidQ programming language. The IDE currently has rich project options, a form designer (similar to Delphi s), and code editor. The BASIC IDE is being coded in Borland® Delphi® . We are currently using Delphi 6, but you should be able to use Delphi 3 or later (Delphi 7 included).
Some of the BASIC IDEs features include:
Form Designer with support for all of RapidQ s components Flexible Code Editor Project Management Written in OO (Object Oriented) Delphi. Some future items that we are working on are:
Code Tip Code Completion CVS Integration Code Editor Macros Point-and-Click access to subroutines, functions, and variables
