Besides, to our knowledge, there is still 121 no available open-source design flow \footnote{There are commercial tools122 such a } for ASIP design even if such a toolwould be valuable in the121 no available open-source design flow for ASIP design even if such a tool 122 would be valuable in the 123 123 context of a System Level design exploration tool. 124 124 \par … … 128 128 only a small fraction of the architecture has to be specialized}, and help ASIP 129 129 designers to focus on compilers, for which there are still many open 130 problems\cite{ CODES04,FPGA08}.130 problems\cite{ARC08}. 131 131 This approach however has a strong weakness, since it also significantly reduces 132 132 opportunities for achieving good seedups (most speedup remain between 1.5x and … … 138 138 %performing efficient instruction selection and/or storage resource (register) 139 139 %allocation \cite{FPGA08}). 140 To cope with this issue, recent approaches~\cite{DAC09, DAC08} advocate the use of140 To cope with this issue, recent approaches~\cite{DAC09,CODES08,TVLSI06} advocate the use of 141 141 micro-architectural ISE models in which the coupling between the processor micro-architecture 142 142 and the ISE component is thightened up so as to allow the ISE to overcome the register 143 I/O limitations, however these approaches tackle the problem for a compiler/simulation143 I/O limitations, however these approaches generally tackle the problem for a compiler/simulation 144 144 point of view and not address the problem of generating synthesizable representations for 145 145 these models.
