Toro streams 16 high-quality analog channels with unlimited trigger flexibility combined with a C6711 co-processor on a 64-bit PCI card
NASA Tech Briefs' 2002 Product of the Year nominee, Toro, is the solution for complex data acquisition, playback and co-processing challenges. Toro combines 16 simultaneous I/O channels at 16-bit resolution and 250kHz sampling with a C6711 DSP. A revolutionary trigger control system is built into Toro's logic and is easily configured for most complex acquisition schemes: external trigger, analog threshold trigger, re-triggered timed or counted frame, pre/post trigger, multi-card synchronized trigger, cascade triggering. A user-configurable hardware alert log records user-selected real-time events that can be used to confirm capture on prescribed signals, reconstruct perfect channel and event alignment and facilitate troubleshooting. With its extensive feature set, system integration and deployment of leading edge industrial solutions are accelerated. Taking advantage of the TMS320C6711 DSP's efficient cache controller and 16 DMA channels, complex programs are easily mapped in Toro's 32MB SDRAM. Toro's 64-bit PCI interface (32-bit compatible) implemented on a Virtex FPGA, sustains over 80MB/s with zero burdening of the target.
Fast implementation of low latency, multi-channel, DSP-based closed-loop control with Toro
Specific features on Toro address the increasing demand for faster servo-control platforms with high channel density. Micro-motion systems, piezo-controlled devices, fast scanners, MEMS control, photonic switches and other technologies now require servo cycles with high channel count and very fast servo loop. Computational requirements can easily be met with today's processors. The challenge, however, rests on the ability to combine a fast CPU with very low latency A/D and D/A stages and synchronize multiple real-time tasks. Toro's firmware includes three useful mechanisms that minimize latency and interrupt rate to the DSP.
- Fast data transfers and minimal DSP interrupt - Toro's logic is optimized to achieve burst rates of 300MB/sec from the A/D and to the D/A with the least CPU involvement. Successive approximation A/D converters are paired, A/D FIFO depth can be set at one sample per channel, and a DMA channel moves data to memory and interrupts the DSP when complete. Following the servo calculation, new values are written to the DAC FIFO prior to exiting the interrupt routine.
- Automatic DAC update - The update of the output to the newly calculated level is done automatically, without requiring DSP interrupt. This event is timed from the last A/D conversion, by adding a user-programmable delay. Again, the user will fine-tune this delay to be slightly above the maximum calculation time. This automatic update ensures the lowest ADC to DAC latency and also provides a fixed update frequency to the drive system.
- Over-run/Under-run flags - These special registers can be monitored during development or in operation, to fine-tune the DAC delay during development and ensure that input and output queues remain synchronized.
Pismo accelerates your Target & Host-side Development.
Pismo Toolsets are complete software development suites specifically crafted for each DSP card in Innovative Integration's Matador & Velocia Series. As DSP systems increase in complexity, it is essential that development software also advances to provide developers with full control of the hardware while remaining intuitive and user friendly. Pismo does just that, in a package that is easily understood and utilized, without burdening the programmer with unwanted peripheral device-specific code details.
DSP/BIOS simplifies development of high-performance, prioritized multithreaded applications, with a kernel footprint and run-time overhead that are negligible for most applications. Pismo supports and extends each of the features of DSP/BIOS through a seamless integration of C++ class libraries, BIOS compliant drivers for each board peripheral and clear illustrative examples. This allows the developer to quickly utilize numerous peripherals of a DSP board concurrently and at full bandwidth. To accelerate host-side programming and mate it with the target code, Pismo includes Armada, a large collection of software components that are easily invoked and configured for functions such as bi-directional interrupts, sophisticated mailbox communication, efficient data streaming, fast creation of graphs, signal post-processing using Intel's NSP libraries and data logging.
