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.
DEDICATED AUDIO COMPONENTS
- ADSP-21371—S/PDIF-compatible digital audio receiver/transmitter
- ADSP-21371—8 dual data line serial ports that operate at up to 33 Mbps on each data line — each has a clock, frame sync, and two data lines that can be configured as either a receiver or transmitter pair
- 16 PWM outputs configured as four groups of four outputs
- ROM-based security features include JTAG access to memory permitted with a 64-bit key Protected memory regions that can be assigned to limit access under program control to sensitive code
- PLL has a wide variety of software and hardware multiplier/divider ratios
- Available in a 208-lead LQFP_EP package

The SHARC Audio EZ-Extender provides users the ability to evaluate audio application on the ADSP-214xx EZ-Board/ EZ-KIT Lite. Software examples are provided in the latest update of VisualDSP++.
The EZ-Extender consists of three Analog Devices AD1939 audio codecs and provides 24 channels of analog audio out, 12 channels of analog audio in. The primary codec operates in both in I2S and TDM mode and can run at sample rates of 48, 96, or 192 KHz. The other two codec are configured to operate in Dual Line TDM mode. The three codecs together can operate in dual line TDM mode for 24 analog channels out and 12 analog channels in at a sample rate of 192KHz.
The audio input and output is available via multiple RCA connectors. A group of switches are available if a user should decide to evaluate the audio codec inputs and outputs in a differential mode. (NOTE: DB25 to XLR cables are not supplied with the EZ-Extender).
