Overall Architecture Framework of ADI DSP Products
ADI’s DSP product lineup can be likened to a multifunctional toolbox, offering different architectural “tools” tailored to various signal processing tasks—ranging from control-oriented applications to high-performance floating-point computing, with broad coverage.
Currently, ADI’s DSP products are mainly divided into the following five major series:
| Series Name | Architecture Type | Brief Description | Application Areas |
|---|---|---|---|
| Blackfin | Fixed-point / Low-power | General-purpose, low-power + embedded control | Audio, video, communication, industrial control |
| SHARC | Floating-point | High bandwidth, suitable for large data stream processing | Audio processors, radar, imaging systems |
| TigerSHARC | SIMD Floating + Fixed-point | Ultra-high throughput, multi-core parallelism | Communication infrastructure, military radar |
| SigmaDSP | Dedicated Audio DSP | Low-cost, efficient audio processing | Consumer audio, in-car audio |
| ADSP-21xx | Fixed-point / Control-oriented | Classic, mature, suitable for control | Industrial control, small embedded systems |
