BA116 - JPEG encoder
Description
The BA116 is a JPEG Intellectual property (IP) core intended for high-speed encoding of grayscale, color or multi-scan images using ISO/IEC 10918-1 baseline coding standard.
The encoder supports all features of the baseline standard, including restart markers, DNL, user-definable comments and application markers.
The BA116 is able to encode abbreviated-format or full-format images. If preferred, pre-defined default entropy and quantization tables are available.
Its autonomous behavior, its simple FIFO-like interfaces and its 100% synchronous structure allow integrating the IP very easily in a complex system with little effort.
The ease of integration of this powerful IP core is reinforced by the stand-alone ability of the encoder that can be used in systems with very little CPU intervention.
