ChipWrights’ ViSP Technology Excels in Image Processing
ChipWrights' Visual Signal Processor (ViSP) technology excels in 2D processing for still image and video data. ChipWrights' enhanced vector architecture enables the processor to work on up to 64 data items simultaneously, while providing high memory bandwidth via an interleaved on-chip memory. This provides the performance of the fastest VLIW processors while maintaining the power and cost characteristics necessary for battery-operated consumer devices.

ChipWrights' ViSP Architecture Delivers High Performance at a Low Cost:
- High performance at consumer-level price and power points
- Low-cost integrated IO for almost any application
- Rich software feature set from the integrated ARM® core
- Flexibility from programmability to support any application
| ChipWrights ViSP Architecture | |
| ChipWrights uses a single-instruction-multiple-data (SIMD) architecture to maximize the logic and power that are devoted to handling data. While other vendors add SIMD as an accessory to their older architectures, it is at the core of what the CWvX processors do. The instruction set, address indexing schemes, and data access mechanisms are tuned for image and video processing. Even the system Direct Memory Access engines are architected to move data in 2D patches. | |

ViSP Vs. DSP
"Most general-purpose DSPs are designed for communications applications - they don't exploit the parallelism possible in image processing because that's harder to find in communications.
Our new DSP architecture—the CWvX Visual Signal Processor—applies techniques from vector architectures to achieve high performance while meeting the low cost and low power needs of portable image-processing devices."
