MCU 8051 IDE is a free software integrated development environment for microcontrollers based on 8051. MCU 8051 IDE has its own simulator and assembler (support for some external assemblers is also available). This IDE supports 2 programming languages: C (compiling with SDCC) and assembly language. This software seems to run only on linux platforms. Although readme file at sourceforge mentioned about the windows version, no windows version of the software found.
