High Performance Convergent Multimedia Blackfin Processor
The ADSP-BF542 processors were specifically designed to meet the needs of convergent multimedia applications where system performance and cost are essential ingredients. The integration of multimedia, human interface, and connectivity peripherals combined with increased system bandwidth and on-chip memory provides customers a platform to design the most demanding applications. For applications that require additional external memory, the ADSP-BF542 family provides product variants specifically designed to interface to either Standard DDR1 or 1.8V Low-Power DDR memory devices.
IP protection has become a necessary part of today’s embedded applications. The ADSP-BF54x provides a security scheme that balances flexibility and upgradeability with performance through the inclusion of a firmware based solution including OTP memory to enable users to implement private keys for secure access to program code.
The ADSP-BF542 provides peripheral flexibility to complement its high performance processing. These rich system level peripherals are well suited for Industrial multimedia applications where multiple standards are prevalent and system performance is required.
For human interface capability, the ADSP-BF542 provides a 32-bit up/down counter that can sense 2-bit quadrature or binary codes as typically emitted by industrial drives or manual thumb wheels. An 8x8 Keypad interface is also included.
To enhance connectivity a USB 2.0 High-Speed On-the-Go (HS USB OTG) with Integrated PHY has been integrated along with standard serial connections provided by multiple on-chip SPORT, SPI, UART, TWI, and CAN interfaces to provide glue-less interfaces to multiple off chip devices including consumer and communication products, Bluetooth, and other application specific interfaces. This level of integration is perfect for the emerging and constantly changing products and standards in convergent multimedia applications.
For interfacing off chip to storage media including hard drives, CD/DVD-drives, and NAND Flash products, the ADSP-BF542 has implemented a SD/SDIO controller, ATAPI-6 controller, and an 8/16-bit NAND flash controller.
Many multimedia enhancements have also been included on the ADSP-BF542 to offload processor MIPS through hardware integration, expand LCD capabilities, and shorten customer development time. A Hardware acceleration block, the Pixel Compositor, has been developed to execute overlay, color conversion and alpha blending. This block significantly reduces processor core overhead associated with software RGB-YUV color conversion and alpha blending.

At least one model within this product family is in production and available for purchase. The product is appropriate for new designs but newer alternatives may exist.
The plug-and-play architecture of USB allows the emulators to be automatically detected and configured by the host operating system. It can also be connected to and disconnected from the host without opening the PC or turning off the power to the PC. A 3-meter cable is included to connect the emulators to the host PC, thus providing abundant accessibility to hard to reach targets.
The HP USB-based emulator also supports the Background
Telemetry Channel (BTC), a non-intrusive method
for exchanging data between the host and target
application without affecting the target system's
