secondary output. Compositing of more surfaces for future video algorithms is possible by
using the TM32 CPU and/or the memory based scaler prior to invoking the
compositing/display engine. This is subject to CPU and memory bandwidth availability.
The PNX8526 contains a 1394 interface with 5C copy protection. The PNX8526 1394 can
simultaneously transmit two transport streams while receiving one transport stream. The
transmitted streams can be partial transport streams (created by PID filtering of an input)
or one of the two streams can be software generated. In the case of receiving a scrambled
1394 transport stream input, the stream can either use the on-chip de-scramblers, or may
be routed to the external companion CA IC for de-scrambling by the POD/CI CA
module(s).
The PNX8526 contains a variety of peripheral interfaces to support both ASTB and DTV
requirements. There are two smart card interfaces, two USB ports, two I
IrDA data UART and two general purpose UARTs, one of which (UART3) is multiplexed
with an SSI interface for soft modem support. The PNX8526 also contains an integrated
IDE controller, which only requires an external isolation buffer to implement a full disk
interface with sustained speeds up to 10 MB/s. A third-party PCI SuperI/O chip may be
utilized to provide peripheral functionality not contained on the PNX8526. Functions such
as IEEE-1284, 10/100 Ethernet, floppy drive support, UDMA66 IDE controllers and others
are currently available in low-cost, commercially-available parts.
