2.8 DSP TI TMS320C6678) Block Diagram
(
The DSPC-8682 PCI-E add-on card adopts TI 8-core DSP TMS320C6678 and its core frequency is 1GHz.

Memory (DDR3)

Four DDR3 memory devices are populated for each DSP on the DSPC-8682 PCI-E add-on card. The
RAM speed is 1333MHz while each DSP connects to four 4G bit (256M x 16) DDR3 devices via DDR
interface.

2.10 SRIO interface

For SRIO connection, It's has two kind of topology to link. The one DSPC-8682 adopts a ring topology
to chain eight DSPs by one lane SRIO interface. One SRIO lane is connected to previous DSP while
another lane is connected to next DSP on DSPC-8682, e.g. the DSP#7 connects the DSP#0 with x1 SRIO
port and connect the DSP#6 with another x1 SRIO port. The other one topology is link to SRIO GEN2
switch IC (CPS-1616) with 1-laneX2 (Supports Up To 5G baud Per Lane) connected to each DSP.
