摘要： A low cost camera by implementing the major functions in host software is provided. This is accomplished by sending raw, digitized data from the camera directly to the host. The increased volume of raw data is handled by either an improved compression/decompression scheme using lossless compression, using lossy compression or using a shared bus with higher bandwidth. By moving such functions as color processing and scaling to the host, the pixel correction can also be moved to the host. This in turn allows the elimination of the frame buffer memory from the camera. Finally, the camera can use a low cost lens by implementing vignetting, distortion, gamma or aliasing correction with a correction value stored in a register of the camera for later access by the host to perform corrections.

摘要翻译： 提供了通过实现主机软件的主要功能的低成本摄像机。 这是通过将原始的数字化数据从相机直接发送到主机来实现的。 原始数据的增加量通过使用无损压缩的改进的压缩/解压缩方案，使用有损压缩或使用具有较高带宽的共享总线来处理。 通过将颜色处理和缩放等功能移动到主机，像素校正也可以移动到主机。 这又允许从相机中消除帧缓冲存储器。 最后，相机可以通过使用存储在相机的寄存器中的校正值来实现渐晕，失真，伽马或混叠校正来使用低成本的镜头，以供主机稍后访问以执行校正。

摘要： Resets on a data processing system are targeted to specific locations of that processing system and have different effects. Some resets are transparent to instruction execution while other resets will interrupt the normal execution of instructions. In addition, in a multi-zone environment resets in one zone do not automatically propagate to the other zone; instead, each zone generates its own resets.

摘要： New and improved methods and apparatus for transmitting data over a data bus. The invention provides a bus system including an external shared bus, an external bus interface, and a resource bus. The external bus interface can be configured to move data between the external shared bus and the resource bus. The bus system can also include a data processing pipeline coupled to the resource bus. The data processing pipeline can include a plurality of components for processing data. Some of the data processing components can be coupled to the resource bus.
