PRODUCT DESCRIPTION
The PI7C8152 is a 2-port PCI-to-PCI Bridge
designed to be fully compliant with the PCI
Local Bus Specification, Revision 2.2. Both the
primary and secondary ports are specified to run
at 32-bit / 66MHz or 33MHz (both ports must be
running at the same frequency in synchronous
mode).
The PI7C8152A supports synchronous bus
transactions between devices on the primary bus
and the secondary bus. The two buses can
operate in concurrent mode, resulting in added
increase in system performance. Concurrent bus
operation off-loads and isolates traffic on a
single bus by allowing a master and target on the
same bus to communicate with each other while
the other bus is busy.
The PI7C8152B has the added capability of
supporting asynchronous bus transactions.
Supported modes of Asynchronous Operation
Primary
Secondary
25MHz to 66MHz
The PCI Local Bus Specification denotes loading
restrictions on the PCI bus. The PI7C8152
allows designers to expand the loading capability
by adding a second PCI bus. On motherboards,
more PCI slots or devices can then be added on
this second PCI bus. On add-in cards, more than
one device can now reside on the add-in card
(PCI Local Bus Specifications specify that each
add-in card may only have one device because
there may only be one connection per PCI signal
in the add-in card connector).
