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.
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.
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.
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.
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.
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.
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.
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.
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.
Software development tools for TORNADO-E stand-alone DSP Controllers include industry-standard C/Assembler compilers, multitasking/multiprocessor real-time OS tools, DSP algorithm development tools, DSP/math function libraries, and more... Please contact MicroLAB Systems for more details.
