High-Performance 32-bit Floating-Point SHARC Processor for Automotive Audio

Manufactured by:

Product Details

The third generation of SHARC®­ Processors, which includes the ADSP-21375 and ADSP-21371, offers increased performance, audio and application-focused peripherals, and memory configurations capable of supporting surround-sound decoder algorithms. All devices are pin-compatible and completely code-compatible with other SHARC Processors such as the ADSP-21367 and ADSP-21369. These members of the SHARC Processor family are based on a single-instruction, multiple-data (SIMD) core, which supports both 32-bit fixed-point and 32-/40-bit floating-point arithmetic formats making them particularly suitable for high-performance audio applications.

The ADSP-21371 offers a high performance at a very low cost 266 MHz/1596 MFLOPs -- within the third generation SHARC Processor family. This level of performance makes the ADSP-21371 particularly well suited to address the increasing requirements of the professional and automotive audio market segments while maintaining a low cost. In addition to its higher core performance, the ADSP-21371 includes additional value-added peripherals such as an S/PDIF transmitter/receiver. The ADSP-21371 also provides a direct interface to synchronous SDRAMs with a 32-bit interface that operates at 133 MHz.

Third generation SHARC Processors also integrate application-specific peripherals designed to simplify hardware design, minimize design risks, and ultimately reduce time to market. Grouped together, and broadly named the Digital Audio Interface (DAI), these functional blocks may be connected to each other or to external pins via the software-programmable Signal Routing Unit (SRU). The SRU is an innovative architectural feature that enables complete and flexible routing amongst DAI blocks. Peripherals connected through the SRU include but are not limited to serial ports, SPI ports, and S/PDIF Tx/Rx.

Product Details

Analog Devices’ cost-effective Universal Serial Bus (USB)-based emulator and High performance (HP) Universal Serial Bus (USB)-based emulator each provide an easy, portable, non-intrusive, target-based debugging solution for Analog Devices JTAG processors and DSPs. These powerful USB-based emulators perform a wide range of emulation functions, including single-step and full speed execution with pre-defined breakpoints, and viewing and/or altering of register and memory contents. With the ability to automatically detect and support multiple I/O voltages, the USB and HP USB emulators enable users to communicate with all of the Analog Devices JTAG processors and DSPs using either a full speed USB 1.1 or high speed USB 2.0 port on the host PC. Applications and data can easily and rapidly be tested and transferred between the emulators and the separately available VisualDSP++ development and debugging environment(sold separately).

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 real-time characteristics.
