— This paper presents the comparison of two design methodologies applied to the design of a co-processor dedicated to image processing. The first methodology is the classical development based on specifying the architecture by directly writing a HDL model using VHDL or Verilog. The second methodology is based on specifying the architecture by using a high(More)
The potential computational power of today multicore processors has drastically improved compared to the single processor architecture. Since the trend of increasing the processor frequency is almost over, the competition for increased performance has moved on the number of cores. Consequently, the fundamental feature of system designs and their associated(More)
This paper presents a contribution to the development of rapid prototyping tools based on data-flow description. In this context, the efficiency of automatic translator tools from the data-flow description to C and/or HDL are presented using two design cases. Moreover, this paper presents the novel concept of the automatic synthesis of interfaces based on(More)
This paper presents some strategies for design space exploration of FPGA-based signal processing systems that are specified using the CAL dataflow language. The actor-oriented, high-level of abstraction provided by CAL allows flexible exploration and consequently results in a wide range of feasible design implementations. We have applied and extended the(More)

This chapter presents a new development of rapid prototyping tools for system design based on data-flow specifications. In this context, the efficiency of tools for the automatic translation from the data-flow programs to C and/or HDL are assessed by means of two design cases. The chapter also introduces the new concept of the automatic synthesis of(More)
