between any of the module sites even with three modules accessing the same destination
module. Access to the PCI bus takes place through TIM site 1. Please see our Web Site at

Figure 4 shows the various dedicated DSP communication channels available on the SMT338
for inter-TIM data transfers.
Figure 4: FPGA-DSP Communication Channels
For developers who want to interface a SMT338 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.
1.4. Sundance Datapipe Link
The Comm-Port connections provided on the SMT338 can be used as Sundance Datapipe
Links for fast data transfers between SMT338-SMT338 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.
