ISA based system design language in HW/SW co-design environment

To develop newly designed processors, it is usually important to develop a software development environment such as assemblers, dis-assemblers, compilers and simulators, as well as designing of target hardware. This is a serious problem for new processor developments, especially for embedded systems. In order to solve this problem, we are developing an ISA based system design language C' (C-like Design Automation Shell) which develops both the processor's hardware core and related software tools, at once. We present the overview of ISA based system design language C'.
