11 INPUT DATA PORT
The Input Data Port (IDP) compromises two units: the serial input port
(SIP) and the parallel data acquisition port (PDAP). Located inside the
DAI of the SHARC processor it provides an efficient way of transferring
data from DAI pin buffers, the external port, the asynchronous sample
rate converters (ASRC) and the S/PDIF transceiver to the internal mem-
ory of SHARC. The IDP specifications are shown in
Table 11-1. IDP Port Specifications
