Title: Porting and Optimization of Audio Codecs on ARM, RISC-V and RX MCUs

Description: Work involves three phases

1. E2A (Literature Survey and Case Study): In this phase, Intern will be asked to do following

• Perform literature survey on topics provided by reviewing materials available from the

Company and other sources

• Synthesis of ideas and organizing them in a logical and coherent fashion in form crisp

notes on the subject (Notes.pdf)

• Document the findings as a technical brief that can be published to the external world

(tbrief.pdf)

• Solve the identified quiz, problem set and lab projects to demonstrate clarity on the

topics provided.

2. E2B (Performance Library): In this phase, Intern will be asked to optimize signal processing

algorithms available in Performance libraries like ARM CMSIS-DSP, Intel MKL and meet/beat

the performance of functions provided by Silicon Vendors.

3. E3 (Production): In this phase, Intern will be asked to optimize 2 to 3 codecs on ARM, RISC-

V and RX MCU platforms. Base code which need to be optimized will be provided by the

Company.

Duration for Phase 1 and 2 is 2 months and Phase 3 is for 3 months.

Skill sets:

1. Programming: Proven low level programming skills in C and Assembly and High level

design/programming Matlab or Python.

2. Theory: Strong foundational knowledge in Computer Architecture and Digital Signal

Processing.

3. Writing: Ability to author technical briefs/papers that can be published and write crisp notes

that assist future work.

4. Reading: Ability to read graduate level text books in Computer Architecture, Digital/Audio

Signal Processing and Audio Coding and solve problems provided in it. Ability to read

IEEE/ACM Papers and implement ideas noted in them.

Traits expectation:

1. Communication: Can articulate the work product and issues in a way that fosters team work

and win-win for all parties.

2. Time Management: Deliver tasks assigned to them on time and quality.

Expected learning:

1. Algorithms in Signal Processing/Audio Coding

2. Performance Engineering in MCUs
