TORNADO-E DSP Controllers have been designed with the "stand-alone" and "universal DSP tool" concepts in mind. Below are only few of what you get with TORNADO-E DSP Controllers:

stand-alone operation
flexible modular construction with daughter-card modules allows immediate off-shelf configuration for customer DSP application via wide selection of AD/DA/DIO daughter-card modules
compatible system architecture with high-performance fixed- and floating-point DSP
communication with external host and peripherals via dual-channel asynchronous or synchronous protocols with RS232C or RS422 I/F
communication with external host computer via USB I/F
real-time clock with battery bak-up for accurate time keeping
industry standard 3U' form-factor
supported by the industry standard DSP software tools
quick time-to-market

Modular Construction of TORNADO DSP ControllersModular construction

TORNADO-E stand-alone DSP Controllers feature unique and flexible modular construction. TORNADO-E DSP Controllers are actually the "DSP constructor" for stand-alone DSP applications and are based around the mainboard, which includes the on-board DSP, RAM, FLASH/EPROM, dual-channel USART, USB I/F, watchdog timer, general purpose I/O and real-time clock. Although the TORNADO-E on-board resources are already sufficient for a variety of control and networking applications, a wide selection of application specific options, i.e. AD/DA/DIO and DSP Coprocessors, might plug as daughter-card modules into the corresponding PIOX-16 and SIOX daughter-card sites onto TORNADO-E DSP controller mainboard. This incremental modular approach delivers outstanding flexibility and allows virtually any off-the-shelf configuration of TORNADO-E DSP Controllers, which will best meet customer application and will save customer time and money should he require further upgrades and modifications.

TORNADO-E DSP Controllers meet the industry-standard 3U form-factor (100x160mm), which allows easy integration of TORNADO-E DSP Controllers into the industry-standard packages and housing.


System Architecture for TORNADO-E DSP ControllersSystem Architecture

TORNADO-E DSP Controllers feature industry standard 3U form-factor and compatible system architecture and DSP environment across different DSP platforms.

TORNADO-E DSP Controllers comprise of the on-board DSP, RAM, EPROM/FLASH, dual-channel USART, USB I/F, general purpose I/O, watchdog timer, real-time clock and expansion sites for application specific PIOX-16 and SIOX daughter-card modules.

PIOX-16 and SIOX daughter-card sites are standard between different DSP platforms for both TORNADO PC plug-in DSP Systems and stand-alone DSP Controllers and allow easy migration between different DSP platforms at a minimum cost and with minimum software modifications.

TORNADO-E DSP Controllers are the industry-standard DSP platforms, which are well suited for virtually any DSP applications, and are supported by the software development tools from the world leading DSP software brands.

Tms320.gif (2457 bytes)On-board DSP

TORNADO-E DSP Controllers are based around state-of-the-art 32-bit  ..2400MIPS fixed-point TMS320C62xx DSP, 32-bit ..8000 fixed-point TMS320C64xx DSP, 32-bit ..1000MFLOPS  floating-point TMS320C67xx DSP, 32-bit ..150MFLOPS floating-point TMS320C3x DSP, and 16-bit ..160MIPS fixed-point TMS320C54x DSP from TI.


TORNADO-E on-board random-access memory (RAM) can be either asynchronous SRAM, or synchronous burst SRAM (SBSRAM), or synchronous dynamic RAM (SDRAM), or combination of those, depending upon the particular type of TORNADO-E DSP controller. Most of TORNADO-E DSP controllers run at 0ws when accessing the on-board SRAM from on-board DSP.


All TORNADO-E stand-alone DSP Controllers have a socket for EPROM/FLASH chip, which contains the application code in the DSP bootloader format. Once external power is applied via dedicated on-board external power connector, and either external or on-board reset signal is released, then the on-board DSP will start bootloading from the on-board FLASH/EPROM.

BS01755_.WMF (6418 bytes)Dual-channel USART

Dual-channel USART (universal synchronous/asynchronous receiver-transmitter) is used as external communication interface in TORNADO-E DSP Controllers.  It supports the industry standard HDLC/X.25, SDLC, MONOSYNC, BISYNC synchronous protocols at up to 10Mbit/s and popular asynchronous UART protocol at up to 2.5MBaud. External electricall interfaces for each channel of USART include either RS422 (up to 10Mbit/s) or RS232C (up to 115kBaud) interfaces. USART is ideal for high-speed networking, telecom and control applications.

Universal Series BusUSB I/F

Latest revisions of TORNADO-E  DSP Controllers (TORNADO-E6x rev.2x and later, TORNADO-E6202, TORNADO-E33, TORNADO-E54x) feature the on-board USB device interface, which is included as a secondary communication interface with host computers.  It supports the industry standard USB rev.1.x protocol at 12 Mbit/s and allows multiple TORNADO-E DSP controllers and many other USB-compatible peripherals to be connected into one USB network hosted by PC.

DD00921_.wmf (2038 bytes)General Purpose I/O

8-bit on-board general purpose I/O (GPIO) of TORNADO-E DSP Controllers features individual programming of direction and DSP interrupt generation, and is included for direct interfacing to external drivers and signal sources without need of system expansion.

AN02030_.wmf (4070 bytes)Watchdog Timer

On-board watchdog timer of TORNADO-E DSP Controllers is an important component for real-time applications with enchanced reliability. For continuos correct operation of TORNADO-E DSP Controller, system software should provide clearing of watchdog timer every 0.8s. Once the clearing signal for watchdog timer is missed due to system hanging or hardware/software crash, then the watchdog timer automatically generates system reset signal for system restart. System software should allow recovery of system state after restart. Usage of watchdog timer is optional.

BS00847A.gif (3051 bytes)Real-Time Clock (RTC)smallnew.gif (926 bytes)

Latest revisions of TORNADO-E  DSP Controllers (TORNADO-E64xx) feature the on-board real-time clock (RTC) with battery back-up, which guarantees accurate time keeping for 10 years. RTC also includes calendar for up to 2100 year, programmable alarm, and programmable secondary watch-dog timer.

Parallel I/O Expansion (PIOX-16) I/F site

TORNADO-E DSP Controllers feature the on-board PIOX-16 site, which allow installation of a wide selection of application specific high-speed AD/DA/DIO PIOX-16 daughter-card modules. Refer to PIOX-16 I/F site specification for details.

Serial I/O Expansion (SIOX) I/F site

All TORNADO-E DSP Controllers feature the on-board SIOX site, which allow installation of a wide selection of low-cost  AD/DA/DIO and DSP Coprocessor SIOX daughter-card modules. Refer to SIOX I/F site specification for details.

PE06074_.wmf (25028 bytes)Software Debugging

TORNADO-E  DSP Controllers provide the on-board MPSD ('C3x) or JTAG ('C54x/C6x) emulation port for connection to external TI XDS510 or MicroLAB'  MIRAGE-510DX scan-path emulator in order to debug the on-board DSP software. After DSP software has been debugged, it should be programmed into on-board EPROM/FLASH.
