ADSP-21065L-EP Enhanced Product GENERAL DESCRIPTION
The ADSP-21065L-EP is a powerful member of the SHARC®
Table 1. Performance Benchmarks
family of 32-bit processors optimized for cost sensitive applica- tions. The SHARC (Super Harvard Architecture) processors
Benchmark Timing Cycles
offer the highest levels of performance and memory integration Cycle Time 16.5 ns 1 of any 32-bit DSP in the industry—they are also the only DSPs 1024-Point Complex FFT in the industry that offer both fixed and floating-point capabili- (Radix 4, with Digit Reverse) 301 s 18,221 ties, without compromising precision or performance. Matrix Multiply (Pipelined) The ADSP-21065L-EP is fabricated in a high speed, low power [3 × 3] × [3 × 1] 148.5 ns 9 CMOS process, 0.35 μm technology. With its on-chip instruc- [4 × 4] × [4 × 1] 264 ns 16 tion cache, the processor can execute every instruction in a FIR Filter (per Tap) 16.5 ns 1 single cycle. Table 1 lists the performance benchmarks for the IIR Filter (per Biquad) 66 ns 4 ADSP-21065L-EP. Divide (y/x) 99 ns 6 The ADSP-21065L-EP SHARC combines a floating-point DSP Inverse Square Root 148.5 ns 9 core with integrated, on-chip system features, including a 544K bit SRAM memory, host processor interface, DMA con- DMA Transfers 240M bytes/s troller, SDRAM controller, and enhanced serial ports.
