IoT integration in Consumer products - Embedded Systems, Architecture, Design, Optimization, Manufacturing, Production support.

Entrepreneur, Co-Founder and CEOChipmonk created M2M/IoT products and solutions, offering Software as a Service (SaaS) and Platform as a Service (PaaS) in Industrial IoT space. Created IoT solution (named OLLO™) for Industrial Process Monitoring, predictive maintenance, Analysis and Optimization. Build the startup operations from scratch. Developed business plans, worked on fund raising, debt planning and equity investments, managed statutory and regulatory compliances with close tracking on expenses ensuring low cash burn rate.Created organization structure as is deemed necessary for a Product Company with eye on short term impacts and long term sustenance plan. Did segregation of what should be done in-house and made partnerships with suppliers and sub-contractors.Creating product roadmap and marketing strategy and execution plan. Defined Product specification, resource planning, defined use cases/customer expectation, priorities and releases. Hired and trained teams for product development (SW/HW), installations and customer support

Major Project Highlights Design of an IrDA controller. Micro-architecture, algorithms and digital logic, RTL design, synthesis and SoC integration. This IP was initially synthesized on 90nm node and later on integrated for two major Japanese Foundry customers. Work continued on customizing for higher technology nodes.Design of JPEG/JPEG-XR Encode/Decode IP Core. Feasibility analysis, micro-architecture, defining product specification/requirements. Architecture for Pre-filters Module. JPEG-XR uses overlapped pre-filter before core transform. The pre-filter design/implementation is under patent filing Design of Multi-protocol Serial peripheral. The protocols integrated are UART, I2S, AC97, I2C, SPI, PCM and IrDA. Feasibility analysis and architecture. Samsung received two patents on MPSI architecture. Also we received Award of Merit in Samsung Worldwide Paper Conference 2009 for the MPSI concept.

Worked on baseband signal processing core implementation for Hardware Demodulator for DVB-H (Digital Video Broadcast) and ISDB-T (Integrated Services Digital Broadcasting – Terrestrial) standards. This was a Co-processor implementation integrated in ARM architecture. Worked on co-processor verification, writing test-benches and firmware implementation.At TI has also worked in Imaging and Audio group. Was responsible for system power management and integration for a range of Digital Multimedia platform SoC based reference designsWorked on TI imaging cores. Was responsible for Requirements definition to final integration and testing plan. Did Power management for imaging core and integrating the power management scheme into the Software Framework. Also worked on Digital Still Camera Reference Design porting

As Principal Engineer for Multimedia group at Avedis Microsystems worked on MP3 decoder, MP3-PRO decoder, and MPEG4 hardware accelerators like Motion estimation and DCT/IDCT blocks. Also did IP roadmap for Short range wireless. At Avedis worked briefly on IEEE802.15.3 OFDM baseband.MPEG4 Hardware Accelerators Motion Estimation and DCT/IDCT were implemented as hardware accelerators for a DSP based MPEG4 platformMP3pro First developed MP3 core which was then extended with PRO functionality. IEEE802.15.3 OFDM WLAN baseband implementation support: This project was secured as a common development roadmap with risk sharing and co-ownership of Intellectual Property. Consulted in the initial design phase for OFDM transceiver chain implementation for IEEE802.15.3

5GHz OFDM WLAN Baseband transceiver implementation: Started with MATLAB simulation of the complete PHY transceiver (IEEE802.11and HiperLAN2). The MATLAB model was then converted to Fixed point C model. The C model was used generating the test vector in compliance with the standard and also for fixing the accumulator ranges and number of bits of computations required at each step to ensure required compliance. A 32 bit RISC processor (ARC Tagent A4) was used as a control processor. The baseband frequency was fixed to 60MHz. The most complex blocks (time and space) for implementation in the transceiver chain were Receiver synchronization, Viterbi decoder and IFFT/FFT.

Worked on defining the Software Architecture for Smart Phones. The architecture was a layered architecture with abstractions defined at OS layer, Platform layer and UI/Application layer. The co-processor engines were defined as components/tasks with dynamic interfacing on running a application chain. The OS used was VxWorks

Working in Embedded Software Group. Providing solutions for Digital Televisions and DVD marketAudio Video Recording Platform layer software development for MPEG2 recorders. Modules worked on are digital encoder, on screen display, sub picture unit, mixer and display plane. The peripherals include1394 Link interface, UART, IIC and IDE interface. OS used was VxWorksWorked as a Project Manager for this project. I was part of the team to scope the project and define the requirements. For the part of the project to be executed at Bangalore, the project planning, resource management, execution and tracking was done by me. I also did the driver layer implementation for Digital Encode and Mixer modules. Digital Media BroadcastPlatform layer software development for Single Chip Set Top Box solutions. This project was a multi-site project with team size of three engineers. Our contribution was mainly for audio video graphics and channel decoder and demodulator. For this project the team traveled to Philips Semiconductor, Southampton. I was part of the team working on component integration, validation and verification.
