Evatronix announces availability of the JPEG 2000 Encoder IP core. The encoder has been optimized for FPGA designs and takes a minimum number of slices while providing full compatibility with ISO/IEC 15444-1 standard that defines the JPEG 2000 format. The JPEG 2000 Encoder IP core allows pictures of virtually any resolution to be compressed. It is one of the first JPEG 2000 encoders to allow processing of Ultra HD images.
Other benefits include configurability of image’s tile size, which can be adjusted to user’s needs and thus significantly increase compression efficiency. As the tile parts are interlaced in the codestream, the available progression applies to the whole image. Also, for even more control over the quality of a final result, compression level can be set through configuration of a bunch of parameters.
Full hardware implementation of TIER-1 and TIER-2 EBCOT encoder allows setting up to 32 different arithmetic entropy coding styles, which give user the ability to precisely set size and quality of output bitstream while eliminating the need to employ any external CPU. Implementation of optimal estimation for transaction rates and up to 7 DWT decomposition levels further increase the core’s ability for customization towards a specific application.
