Chennai, NFAPost: Indian Institute of Technology Madras Researchers have successfully booted up ‘MOUSHIK,’ an indigenously-made Microprocessor. MOUSHIK is a processor cum ‘system on chip’ that can cater to the rapidly-growing IoT devices, an integral part of Smart Cities of a Digital India.

‘MOUSHIK’ was conceptualised, designed and developed at the Pratap Subrahmanyam Centre for Digital Intelligence and Secure Hardware Architecture (PS-CDISHA) of the RISE Group, Department of Computer Science and Engineering, IIT Madras.

The impact of the completely-indigenous development process is the showcasing of an Indian ecosystem for designing, developing and fabricating end-to-end systems within the country, leading to self-sufficiency. The Project is funded by the Ministry of Electronics and Information Technology, Government of India.

Elaborating about the processes behind ‘MOUSHIK,’ Prof. Kamakoti Veezhinathan, Reconfigurable Intelligent Systems Engineering (RISE) Group, Department of Computer Science and Engineering, IIT Madras, said, “There are three steps involved in the making of a microprocessor, namely Design, Fabrication and Post-Silicon Boot-up. All three processes for MOUSHIK were undertaken in India, demonstrating an ‘Atma Nirbhar’ ecosystem in Digital Design Productisation.”

Prof. Kamakoti said, “The Design of the Microprocessor, Motherboard Printed Circuit Board Design, Assembly and Post-Silicon Boot-up were done at IIT Madras. The foundry-specific backend design and fabrication was undertaken at Semi-Conductor Laboratory of Indian Space Research Organization (ISRO) in Chandigarh and manufacturing of this motherboard was done at Bengaluru. Shakthi MOUSHIK SOC will constitute the heart of an indigenously-developed motherboard called ‘Ardonyx 1.0.’”

MOUSHIK is an Indigenous RISC-V Microprocessor and is the third chip of the SHAKTI family, all of which were conceptualised and developed by this Centre and were first time ‘silicon successes.’

The Field Applications of ‘MOUSHIK’ include

1.    Smart cards including Credit cards, ID Cards, Debit cards, Travel Cards for Metros and Driving Licenses

2.    Electronic Voting Machines (EVMs)

3.    Office Management Systems including Attendance, surveillance cameras and safe locks

4.    Personalised Health Management Systems

5.    Consumer Electronics including but not restricted to Washing Machines and Water pump monitoring systems

The Technical Aspects of the MOUSHIK Processor Silicon are:

  • The MOUSHIK Silicon is manufactured using 180 nanometer technology
  • Die size of 5.315 X 5.155 sq.mm
  • It has 103 functional IOs
  • Package – 256 pin CQFP Package
  • Core Voltage – 1.8v
  • IO Voltage – 3.3v
  • Gate Count – 647k
  • Instance Count – 210k
  • DFT – SCAN, JTAG

The SHAKTI microprocessor system design is based on RISC-V ISA (Instruction Set Architecture). RISC-V is an open, free ISA enabling a new era of processor innovation through open standard collaboration. ISA is the programming or machine language and provides commands to the processor instructing it on the functions to be executed.
