1.5 GFLOPS Performance and Audio-Centric Peripherals
The ADSP-21371 and ADSP-21375 32-bit/40-bit floating point processors simplify
the development of high-performance
audio products and reduce overall
system cost. Their 266MHz core, on-chip
memory capable of supporting the latest
surround-sound algorithms and audio-centric
peripherals provide superior performance
while maintaining a low cost.
ADSP-21371 and ADSP-21375 are third-generation
SHARC processors based on a SIMD (Single-Instruction, Multiple-Data) SHARC core. They are designed to simplify product development, speed time to market and reduce system costs for a variety of high-performance audio applications including automotive and professional audio
systems, audio/video receivers and digital
audio amplifiers, as well as telecommunications,
industrial and medical products.
Both processor devices are pin-compatible
and code-compatible with other SHARC®
processors such as the ADSP-21367 and ADSP-21369.
On-Chip Memory
ADSP-21375 features 0.5Mbit SRAM and 2Mbit mask-programmable ROM, while the ADSP-21371 offers 1Mbit SRAM and 4Mbit mask-programmable ROM, and a 32-bit external memory interface (133MHz).
The highly efficient external memory interface
simplifies software and hardware development
by speeding algorithm development.
With the glueless connection to both
synchronous (SDRAM) and asynchronous
memory devices, embedded audio designers
can take advantage of the most cost-effective
memory technology for their individual
product
Digital Audio Interface
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 blocksmay be connected to
each other or to external pins via the software-programmable Signal Routing Unit
(SRU). Peripherals that can be flexibly connected
through the SRU include serial ports, SPI ports, and like implemented in the ADSP-21371, an S/PDIF transceiver/receiver.
