ADSP-21261 is a 150MHz SIMD on-chip dual-ported SRAM SHARC processor for use in cost sensitive and signal processing applications. The ADSP-21261 is based on the SHARC (SIMD) core that supports execution of 32-bit fixed-point and 32-/40-bit floating-point arithmetic formats. With its core running at 150MHz (6.67 ns instruction cycle time), the ADSP-21261 is capable of executing complex Fast Fourier Transform (FFT) operations-1024-point complex FFT in 61us. The processor’s single-instruction, multiple data (SIMD) mode effectively doubles the processor performance. The ADSP-21261 offers a high level of integration, including 1Mbit of on-chip dual-ported SRAM and 3Mbits of mask programmable ROM memory.
