two unique features of the v350epc make it the highest perform- ance pci bridge on the market. one is the size of the fifo structure; 640 bytes of fifo storage gives you plenty of buffering to handle con- tinuous transfers of large data streams without tying up the local or pci buses. the dynamic bandwidth allocation feature of the fifos allows you to adjust the ?raining?and ?illing?of the read and write fifos to most efficiently meet the requirements of the data streams. you can balance your bus utilization to maximize over- all system performance. the priority of reads, writes, and fifo flushes can be independently programmed to maintain strict data coherency. the v350epc provides the most flexible, highest performance, and economical way to add pci connectivity to applications like imaging and networking. whether you?e creating a system with the i960 or powerpc cpu as the pci master or designing an intelligent add-in card, or even a processor-less application, the v350epc from v3 semiconductor is the ideal choice. about v3 semiconductor v3 semiconductor has been providing embedded systems designers with innovative products since 1987. v3 products are supported throughout north america, europe, the middle east and the far east by a network of distributors and manufacturers?representatives. for more information on the v350epc, or our other i960? and powerpc processors support components, please contact: cost effective solutions that simplify embedded system design! v3 semiconductor 2348g walsh ave. santa clara, ca 95051 phone: (408)988-1050 fax: (408)988-2601 toll free: (800)488-8410 (canada and us) www.vcubed.com / or www.v3semiconductor.com typical applica tions ?997 v3 semiconductor corp. v3 semiconductor retains the right to make changes to either the documentation, specification or c omponent without notice. i960 is a registered trademark of intel corporation. powerpc is a trademark of ibm corporation. target-only application
