2.5.6 Controller Processor Card (DSP/ARM) (P-CPC-G)
The Controller Processor card (P-CPC-G) uses an Advanced RISC Machine (ARM)
processor and a Field-Programmable Gate Array (FPGA) based Universal Asynchronous
Receiver/Transmitters (UARTs) to serve as a hub for all data communication and to
coordinate the main control functions required by the PAGASYS GEN II system. (See
Figure 6.) The Controller Processor card also contains a Digital Signal Processor (DSP)
to carry out all digital audio processing.
In addition to the UART communication interfaces, the Controller Processor card also
includes a network switch, a SATA interface for an on-board hard disk (for primary and
backup data storage), and an SD card interface.
The Controller Processor card also provides an interface for an optional Digital Audio
Network Through Ethernet (Dante) module to provide up to 16 channels of bi-directional
digital streaming over an Internet Protocol (IP) network.
For external communications, the Controller Processor card contains several
communications interfaces, including an Inter-Integrated Circuit (I
2
C) bus, USB Master/
Slave interfaces, and an RS232 port.
The card includes a battery holder for a 3 V Lithium CR16xx coin battery cell, which
supports the processor card real-time clock when power is removed from the Controller
Chassis. The processor card is shipped with the battery inserted in the battery holder, but
the battery is not operational until the Mylar insert is removed from the battery. See the
Controller Chassis Operations section of this document for the procedure to remove and
replace the battery.
