ADSP-21061L

The ADSP-21061 is a member of the powerful SHARC family of floating point processors. The SHARC-Super Harvard Architecture Computer-are signal processing microcomputers that offer new capabilities and levels of integration and performance.

The ADSP-21061 is a 32-bit processor optimized for high performance DSP applications. The ADSP-21061 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-21061 has a 20 ns instruction cycle time operating at up to 50 MIPS. With its on-chip instruction cache, the processor can execute every instruction in a single cycle. Table I shows performance benchmarks for the ADSP-21061/ADSP-21061L.

The ADSP-21061 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.
