We present a toolkit for embedded system VLSI design. Toolkit AKKA1 [1], consists of design space exploration through profiling, estimation, partitioning, cosimulation and cosynthesis subtools. Most of tasks in this list can be classified into HW/SW codesign domain. We will describe proposed design flow, starting from design capture and ending with generation of unique synthesis-able VHDL code for HW, and assembler code for SW. Our approach is oriented to control and memory intensive systems. It is illustrated by a Mandelbrot plotter in this paper.
