Application of bus emulation techniques to the design of a PCI/MC68000 bridge
(Elsevier, 2002)
Bridges easy the interconnection and communication of devices that operate using different buses. In fact, we can see a computer as a hierarchy of buses to which devices are connected. In this paper we design a PCI/MC68000 ...

A Topologically Consistent Color Digital Image Representation by a Single Tree
(Springer, 2021)
A novel, flexible (non-unique) and topologically consistent representation called CRIT (Contour-Region incidence Tree) for a color 2D digital image I is defined here. The CRIT is a tree containing all the inter and intra ...
