DoGav Systems announces a microcode module supporting
PROFIBUS DP for
PowerQUICC and QorIQ devices
The
new module fully supports the PROFIBUS
(Process
Field Bus) DP
(Decentralized Peripherals)
standard on
Freescale’s PowerQUICC
and QorIQ processors with programmable CPM or QUICC Engine
Controller (e.g. MPC82xx,MPC8306 and P1021), and therefore it is able to offload
a substantial amount of processing resources from the host
processor.
Available immediately, the new module
features include:
-
Slave(s) and Master support
-
Master automatically switches between Slaves
-
Writing directly to memory-mapped
I/O devices or read from them (or both) if instructed to. This
feature significantly frees the host processor.
-
The host processor may add/remove
new Slaves dynamically (Master port only).
-
Master retries to “silent Slave” is
handled automatically. Number of retries is configurable.
-
Corresponding statistics counter is
updated.
-
Maskable interrupts are generated
per various events
-
A number of statistics counters.
-
Generation of frame checksum as well
as frame terminators (0x16)
-
Three types of timestamps are
provided (Receive, Transmit and “Last touch”)
-
Transmit and Receive functions use
the
“classic” buffer descriptors model
-
12Mbps with 8 times oversampling
(device dependent clock).
-
Master support up to 126 Slaves
-
Master automatically generates tokens
-
Each port records all its PROFIBUS
network activities, encapsulates them into Ethernet UDP frames
and send them to PC tracer (PC parser s/w is provided)
-
Customizable. Can be customized to
meet specific customer requirements.
-
Loadable on Freescale's PowerQUICC
and QorIQ devices with programmable CPM or QUICC Engine
Controller
