Multimedia Codecs on various ARM Platforms by Tata Elxsi Limited

Audio and Voice Solutions

Product Description

Tata Elxsi offers a rich set of licensable Audio/Video components on ARM7, ARM9, ARM9E Platforms, targeted to help OEM/ODM's to get to market faster, and save technology development efforts.

Tata Elxsi A/V Codec libraries are standards based reusable components with extensive well-documented APIs. In most cases the codecs are designed to be OS independent and allows quick customisation of the existing code to target hardware. All the codecs are Fixed-point arithmetic implementation using ANSI C and ARM Assembly coding

TEL’s codec solutions keep the below mentioned aspects as the defining criteria’s in the design stage:

• Re-entrant and multithread safe
• Re-locatable
• No memory leaks and corruptions
• Least usage of memory and MIPS
• No global writes
• Shall be adaptive for limited "large sized" contiguous memory
• Shall be adaptive for memory partitioning
• Core codecs suitably abstracted through a rich set of APIs
• Features supported by codecs shall not be dependent on the APIs
exposed for system
