IP-core Architecture Overview

​Encoder Architecture

Multiple Component Transformation (MCT)

The first stage of the encoder is the Multiple Component Transformation, It may be used to improve compression efficiency, by decorreleting the luminance from the chrominance, e.g. converting RGB to YCbCr. 3 modes are accessible: Pass-through, reversible Lossless transform (RCT, prescribed for Lossless encoding)) and the irreversible transform (ICT).. Both, RCT and ICT, transformations are implemented with 18-bit fixed point precision.

Discrete Wavelet Transform (DWT)

A bi-dimensional wavelet decomposition of the sub-bands is performed with either the Le Gall (5/3) filter bank or the Daubechies (9/7) filter bank. The 5/3 filter is recommended for lossless encoding while the 9/7 filter offers a better compression efficiency for lossy encoding. Used with an 18-bit fixed point precision.

Quantizer

The coefficients of the wavelet sub-bands are quantized. The quantization steps are defined by the user and can be different for each sub-band.

Entropy encoder

Each wavelet sub-band is divided into several code-blocks and encoded using an Entropy Encoder. The encoder is divided into two blocks: the Context Modeler and the Arithmetic Encoder. The Context Modeler successively encodes each bitplane of the code-block by sending information describing the neighborhood of each bit to the Arithmetic Encoder. With this information the Arithmetic Encoder encodes each bit in order to generate the compressed bit-stream.

Rate Allocator

In order to maximize image quality within the bitrate boundaries fixed by the user, the Rate Allocator selects the information encoded by the Entropy Encoder that will be included in the final code stream.

JPEG 2000 Generator

The JPEG 2000 Generator is responsible for generating the final codestream so as to provide a fully compliant JPEG 2000 image. This codestream generator is also responsible for the codestream structure accordingly to the scalability order selected by the user: by Resolution (R), by quality Layer (L), by Position (P) or by Component (C).

External memory

A first memory buffer is used to provide the most efficient DWT processing. This buffer, containing one DDR-SDRAM external memory, enables the encoder to provide a buffer of at least one frame. A second memory buffer is then provided to compute efficiently the rate allocation. This buffer is also based on one DDR-SDRAM memory. The DDR-SDRAM types included will depend on the user specification and required product solution.
intoPIX provides the optimal memory controller management that ensures the memory interfacing of the J2K cores and other processing .

Interfaces

Input and output interfaces are based on FIFO protocols, and a burst of two pixels (in RBG, XYZ or YUV) is required at the input interface.

Process Controller

Taking full advantage of JPEG 2000 intra-frame coding, the intoPIX Encoder Process Controller accurately manages the frame stream. When there is no video to encode the processor will continue to provide the latest encoded frame, or stop outputting compressed data according to the user command. This process also configures the different JPEG 2000 options for the full encoding chain.

​Decoder Architecture

JPEG 2000 parser
The JPEG 2000 parser analyses the main and tile-part headers of the JPEG 2000 codestream and sends the compressed bit-stream to the entropy decoder.

Entropy decoder
The reconstruction of each wavelet sub-band divided into several code-blocks is achieved by two blocks: the Context Modeller and the Arithmetic Decoder. The Context Modeller successively decodes each bit-plane of the codeblock by sending information describing the neighbourhood of each bit to the Arithmetic Decoder. With this information, the Arithmetic Decoder decodes the bit-stream.

Inverse Quantizer
The coefficients of the wavelet subbands are inverse quantized. The quantization steps are defined in the main header of the JPEG 2000 file and can be different for each subband.

External memory
A frame memory buffer is used at the Inverse Quantizer output and enables an efficient IDWT processing. This buffer, containing a DDR-SDRAM external memory, always keeps at least one valid frame that can be repeated when convenient.

Inverse Discrete Wavelet Transform (IDWT)
A bidimensional wavelet recomposition of the subbands is achieved. Two filter banks, with a 18-bit fixed point precision, may be used: either the Le Gall (5/3) filter bank prescribed for lossless encoding or either the more complex Daubechies (9/7) filter bank for lossy encoding.

Multiple component transformation (MCT)
In the JPEG 2000 standard, in order to improve compression efficiency, multiple component transformations can be used. Depending on the wavelet filters used, different transformations are defined. The reversible transform (RCT) is used with the 5/3 filter, and the irreversible transform (ICT) with the 9/7 filter. Both transformations are implemented with a 18-bit fixed point precision.

Error Handling
The decoder is designed to detect errors in the input data and detection achieved at the main headers, and at the
coherence of tag trees. When an error is detected, specific error codes are sent to the device managing the decoder. In the case of a corrupted frame codestream, the decoder can try to decode the next frame. This can be repeated until a correct frame is encountered. If no frame can be decoded during the elapsed time determined by the frame rate, the previous correctly decoded frame is sent to the output to prevent display artifact.

Process Control
Taking advantage of the JPEG 2000 intra-frame coding, the decoder controller can manage the stream at the frame accuracy (or below with Ultra Low Latency mode). When there is no data to decode at its input, the decoder can loop on the latest decoded frame, output a black frame or stop to output frames. By controlling the input stream and the output options, the decoder controller can manage pause, step by step, slow-motion, fast forward and rewind, and random access.
Interfaces The input receives data by 32-bit bursts of in Little or Big-Endian representations. A burst of two pixels (RGB, XYZ or YUV) is output. The output clock depends on the sequence frame rate and picture size.
