SHARC, 44MHz, 150 MFLOPS, 3.3v, floating point
The ADSP-21061L is the newest member of the powerful SHARC ® family of floating point processors. The SHARC ® are signal processing microcomputers that offer new capabilities and levels of integration and performance. The ADSP-21061L is the low power (3.3 volt) version of the ADSP-21061. The ADSP-21061L is a 32-bit processor optimized for high performance DSP applications. The ADSP-21061L combines the ADSP-21000 DSP core with a dual-ported on-chip SRAM and an I/O processor with a dedicated I/O bus to form a complete system-in-a-chip.
Fabricated in a high-speed, low-power CMOS process, the ADSP-21061L has a 25 ns instruction cycle time operating at 40 MIPS. With its on-chip instruction cache, the processor can execute every instruction in a single cycle.
The ADSP-21061L SHARC combines a high-performance floating-point DSP core with integrated, on-chip system features, including a 1 Mbit SRAM memory, host processor interface, DMA controller, serial ports and parallel bus connectivity for glueless DSP multiprocessing.
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.
