taken to process a single frame of size 1 kB, for different bus architectures. It can

be seen that the times required by both variants of the FLEXBUS architecture are

smaller compared to conventional architectures. FLEXBUS and its reconfi guration

policies are also seen to perform close to the ideal case, which assumes no recon-

fi guration overhead, and an ideal reconfi guration policy having full knowledge of

future bus traffi c.

8.6 SUMMARY

In this chapter, we presented custom bus-based communication architectures that

attempt to overcome limitations of commercially available standard bus-based ...
