SVE-JPEG-E SpeedView Enabled JPEG Encoder Core

On this page: Description | Features | Applications | Block Diagram | Functional Description | Support | Verification | Deliverables

The SVE-JPEG-E core implements a high-performance image encoder that produces SpeedView™ enabled JPEG data streams.

Integrating the SpeedTags™ technology the SVE-JPEG-E outputs compressed streams that are compatible with SpeedView™, a member of Scalado’s CAPS™ imaging suite which is focused on providing enhanced functionality to camera equipped mobile devices. CAPS™ compatibility combined with a hardware architecture being able to process more than 500MSamples/sec, makes the SVE-JPEG-E a unique solution for mutli-megapixel applications.

Furthermore, the SVE-JPEG-E can be configured to output streams compatible to baseline JPEG, or non-standard motion-JPEG streams. Finally the core can be enhanced with a bit-rate control block, which may benefit applications that have tight bandwidth constraints.

Designed for ease of integration the core includes FIFO-like pixel and stream input/output interfaces. The deliverables include a software bit-accurate model that facilitates system on chip verification.

Block Diagram

Functional Description

The SVE-JPEG-E core is configured by feeding it with JPEG headers, which contain table specification, image format, and encoding options data. The core's configuration can be modified after the encoding of one or multiple frames. Image samples in any color space format are input to the SVE-JPEG-E in a MCU block by MCU block, raster scan order.

Consuming a single clock cycle per image sample, the SVE-JPEG-E can address the most demanding frame-based video compression applications. The SVE-JPEG-E outputs a complete JPEG data stream, including JPEG headers, the size of which can be dynamically controlled if the optional rate-control block is used. Output JPEG stream can be either compatible to JPEG standard or to CAPSTM imaging suite.

Support

The SVE-JPEG-E core as delivered is warranted against defects for ninety days from purchase. Thirty days of phone and email technical support are included, starting with the first interaction. Additional maintenance and support options are available.

Verification

The SVE-JPEG-E core has been verified through extensive simulation and rigorous code coverage measurements. It has also been proven in FPGA technologies.

Deliverables
