چکیده |
From high level synthesis point of view, target design can be divided into two parts: controller and datapath.
Single shared bus is a suitable structure for datapath synthesis regarding interconnections costs which suffers
from several drawbacks such as its low data communication bandwidth. It has also been shown that the wordlength
of functional units has a great impact on design costs. A combination of both methods is the core idea of
this paper which is offering an improved communication structure. In this method datapath is partitioned into
groups connected to segmented shared buses and every partition has a different width and all the functional
units connected to a bus partition have the same input/output word-lengths. Having controlled the group binding
and word-length of the functional units, as well as the other synthesis parameters, a high-level synthesis tool is
introduced to implement DSP algorithms in digital hardware. The tool uses a multi-objective optimization genetic
algorithm to minimize the circuit area, delay, power consumption and digital noise by selecting optimal
grouping and word-length for the shared bus structure. Results demonstrate that savings can be made in the
overall system costs by applying this method. |
