Billerica, Mass.Operating at 400-Mbytes/s for high-bandwidth data transfers, ICS Sensor Processing (Interactive Circuits and Systems), part of Radstone Embedded Computing, rolls out its ICS-8500 PMC (PCI mezzanine card). It's claimed to be the first available PMC with the performance of FPDP II (front-panel data port), yet it's based on a PCI 2.2 (64/66) PCI bus interface.
A word about FPDP. ICS Sensor Processing invented FPDP back in 1994 as a method of cost-effectively providing high-speed connectivity between two boards. FPDP provides deterministic sustained-bandwidth communications not impeded by contention for bus resources.
What's more, FPDP is now an ANSI/VITA standard, meeting ANSI/VITA 17-1998 specs. It's also widely accepted as an optimum method of achieving high-speed data transfer between sensors and DSPs (digital signal processors).
Transmit Or Receive
Back to the ICS-8500. It can be configured as either a transmitter or a receiver. As such, it should serve well in very high performance applications where the requirement is for multi-channel high-rate sensor data transfers across a single backplane.
Its 400-Mbyte/s speed surpasses the 160-Mbytes/s speed of FPDP. The use of FPDP II also lets the potential bottleneck of VME or PCI backplanes to be bypassed, ensuring that data transfer rates are maximized while minimizing impact on other system functions.
The 400-Mbyte/s FPDP II interface is provided via the P4 connector: when the ICS-8500 is communicating with a non-FPDP II device, it automatically reverts to ANSI/VITA 17 FPDP operation at 160-Mbytes/s.
Available in convection-cooled and conduction-cooled versions, the ICS-8500 offers similar functions to the company's ICS-500-R and ICS-500-T PMCs, but is configurable under software control as either a receiver or transmitter.
The ICS-8500 also features 8-Mbytes of swing buffer memory, setting it apart from products that provide only limited FIFOs.
In Transmit mode, the board provides an FPDP/TM (Transmit Master) interface. In addition to a continuous data transmit capability, a Loop mode of operation is available. In Loop mode, a fixed length of data equal to the programmed buffer length is written to both banks of the swing buffer. When triggered, this data is repetitively generated and transmitted by the FPDP output interface.
In receive mode, the board provides both FPDP/R (Receive) and FPDP/RM (Receive Master capabilities. A key feature is the PMC's ability to perform a corner turning function. This software-enabled feature re-orders multi-channel data from channel ordering by time-to-time ordering by channel.
Device drivers for Wind River VxWorks, Linux, and Windows are available.
