Abstract | In complex SoC design, the reusable IP is very useful to achieve the whole system with high verification. Based on this issue, a hardware and software (HW/SW) co-design approach can obtain maximum performance, and is easily integrated with the other functions to complete the system. This paper presents the multi-standard audio decoder design with hardware/software co-design flow. First we need to generate the deliverable IP as the hardware design part, and then construct the other modules as software design part. In order to save the hardware cost, the hardware accelerator is applied with the fast algorithm and some techniques on architecture design. Not only just an implementation on the complex system design, our design flow can help designer to profile and analyze the performance in system level. With an aid on it, we can provide a multi-standard decoder with hardware accelerator to improve system performance. The implement result shows that it only needs 3.6 MHz in real-time constraint. With this low operation frequency, the multi-standard audio decoder with HW/SW co-design approach can take advantage on low power constrained application, especially on portable device. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
