S. Sugawa et al., AN AREA-EFFICIENT HARDWARE SHARING FILTER GENERATOR SUITABLE FOR MULTIPLE VIDEO FORMAT CONVERSIONS, IEEE transactions on consumer electronics, 43(3), 1997, pp. 848-854
A software program which automatically generates area-efficient circui
ts for multiple video format conversion filters by using new hardware
sharing technique has been developed. The circuits employing this new
technique share most of hardware between all filters by utilizing the
feature that these filters never operate at the same time. Its perform
ance has been demonstrated by applying the technique to an LSI which c
onverts formats such as NTSC and SDTV for plural types of HDTV monitor
. The number of gates for all filters in this chip was decreased from
99,053 to 23,833 by the software program. As a result, all the hardwar
e was successfully integrated into a single chip.
