new products DaVinci devices for high-deﬁnition video designs Texas Instruments has introduced a DaVinci processor with ARM host control and development tools for use in portable, high-deﬁnition (HD) video products. The TMS320DM355 digital media processor provides HD video performance and double the battery life of today’s HD products. Tuned for applications such as digital cameras, IP video cameras, digital photo frames and video baby monitors, the DM355 processor consists of an integrated video processing subsystem, an MPEG-4-JPEG co-processor (MJCP), an ARM926EJ-S core and peripherals. The processor is available in clock speeds of 216 MHz or 270 MHz, which allows for a scalable line of products. Developers can re-use intellectual property (IP) from the DaVinci technology portfolio or use IP from the open-source resources for ARM-based processing to speed them throughout the development process. Other applications that will beneﬁt from implementing the DM355 include commercial products, such as medical imaging, low-cost digital video recorders and portable test equipment. The MJCP video/imaging coprocessor provides HD MPEG-4 SP encode or decode at 720p and 30 frames per second and JPEG encode or decode at 50 Mpixels per second. The video processing subsystem, which is featured on all DaVinci devices, integrates a preview engine, histogram, resizer and processing performance, and up to 270MHz of ARM processing capabilities are still available for product differentiation. The the DM355 digital video evaluation module (DVEVM) development tool includes a suite of peripherals, such as high speed USB 2.0 On-The-Go. The integrated 10-bit D/A converter and video encoder also saves developers up to $2 in the bill of materials. It also includes the production-qualiﬁed HD MPEG-4 and JPEG codecs without the need to pay licensing fees or royalties. Depending on the application, the DM355 consumes approximately 400mW during HD MPEG-4 encoding and 1mW of stand-by power. As an example, this means that consumers using DM355-based digital cameras in video mode can expect to record 80 minutes of HD video using two AA batteries. The DVEVM includes optimized MontaVista Linux, an uboot loader, and drivers for the complete peripheral set. Rounding out the DVEVM are the JPEG, MPEG-4 SP and G.711 codecs plus video input/output, audio in/out, an external EMAC, USB 2.0 On-TheGo and JTAG for test. ORCAD schematics are also available at no charge. www.ti.com on-screen display all in hardware. The MJCP provides the equivalent of 400 MHz of digital signal processing (DSP) to achieve HD video, while the video processing subsystem tasks equate to approximately 240 MHz of performance on a DSP. Combined, the MJCP and video processing subsystem provide the equivalent of up to 640 MHz of DSP Z8 Encore! XP family optimized for fan and motor control The latest addition to the Zilog Z8 Encore! XP portfolio is the Z8F083A series ﬂash microcontroller (MCU). The MCU provides the fundamental features required for electric fans and universal motor control. Functions on-chip include a 2.5 times faster internal precision oscillator and 5 times faster A/D converter over competing products in its class. This equates to faster response times for critical motor control loop operations. Also included are current and temperature monitoring. The series provides a single-pin onchip debugger port for in-system Flash 40 programming and debugging, a feature provided by the entire Z8Encore! XP family. The family supports up to 8kbytes of ﬂash memory, 256 bytes of register RAM, and is pin-for-pin compatible with other members of the Z8 Encore! XP family, allowing a migration path from 1kbytes up to 12kbytes. The Z8F083A Series also includes a targeted peripheral set featuring an up to eight channel, fast 2.8 µs ‘best in class’ successive approximation register (SAR) A/D converter, an ‘on-chip’ 20 MHz internal precision oscillator that eliminate the need of an external crystal or oscillator, and 100bytes of nonvolatile data storage for storing system parameters or user data. The devices also include two enhanced 16-bit timers/counters featuring capture, compare and PWM capabilities, and one analog comparator, providing increased design ﬂexibility in end applications. A development environment uses a USB smart cable and opto-isolated USB smart cable and the family is also supported by the ZDS II integrated development environment with ANSI C-Compiler. www.zilog.com AUGUST - SEPTEMBER 2007 | embedded systems design europe | www.embedded.com/europe 040_ESDE.indd 40 6/09/07 13:20:29 http://www.ti.com http://www.zilog.com http://www.embedded.com/europe
