SHARC Processor ADSP-21483/ADSP-21486/ADSP-21487/ADSP-21488/ADSP-21489
2021-12-03
■GENERAL DESCRIPTION
●The ADSP-2148x SHARC® processors are members of the SIMD SHARC family of DSPs that feature Analog Devices’ Super Harvard Architecture. The processors are source code compatible with the ADSP-2126x, ADSP-2136x, ADSP-2137x, ADSP-2146x, ADSP-2147x and ADSP-2116x DSPs, as well as with first generation ADSP-2106x SHARC processors in SISD (single-instruction, single-data) mode. The ADSP-2148x pro-cessors are 32-bit/40-bit floating point processors optimized for high performance audio applications with large on-chip SRAM, multiple internal buses to eliminate I/O bottlenecks, and an innovative digital applications interface (DAI).
●Table 1 shows performance benchmarks for the ADSP-2148x processors. Table 2 shows the features of the individual product offerings.
■FEATURES
●High performance 32-bit/40-bit floating-point processor optimized for high performance audio processing
●Single-instruction, multiple-data (SIMD) computational architecture
●On-chip memory—5 Mbits on-chip RAM, 4 Mbits on-chip ROM
●Up to 450 MHz operating frequency
●Code compatible with all other members of the SHARC family
●The ADSP-2148x processors are available with unique audio-centric peripherals, such as the digital applications interface, serial ports, precision clock generators, S/PDIF transceiver, asynchronous sample rate converters, input data port, and more
●For complete ordering information, see Ordering Guide on Page 70
●AEC-Q100 qualified for automotive applications
