Figure 5: FPGA-DSP Communication Channels
For developers who want to interface a SMT358 to a C4x or C6x TIM like the SMT302,
SMT331 or SMT332 via Comm-Ports or the Global Bus, a Comm-Port interface and a Global
Bus interface are available from Sundance Multiprocessor Technology IP Centre.
Sundance Datapipe Links
The Comm-Port connections provided on the SMT358 can be used as Sundance Datapipe
Links for fast data transfers between SMT338V2-SMT358 or ‘C6x TIM based boards like the
SMT335.
An SDB interface is used and offers up to 100 MHz on copper and 50 MHz on flat-ribbon
cables like the FMS used on the Sundance range of carrier boards.
