Fig. 5.4 Moving data back and forth between FPGA and external memory can easily lead to exceed
the available bandwidth
Fig. 5.5 The overall memory bandwidth can be increased by adding to the design multiple memory
devices
According to the previous analysis, since the memory bandwidth required can
exceed that available in current memory devices, a straightforward solution to over-
come this problem would consist in using multiple memory devices as outlined in
Fig. 5.5 . However, although the strategy depicted in the figure could solve memory
bandwidth issues, this strategy would have on the other hand some disadvantages.
In particular, using multiple memory devices to increase the overall memory band-
width would lead to increased costs, power consumption, overall complexity, and
