Shakti- India's First Microprocessor

By Kajal Vats|Updated : August 19th, 2020

Hi Gradians!

Every Engineer must be aware of his/her responsibility towards the nation as Engineers play a significant role in every walk of life. It's their responsibility to convert knowledge of basic sciences into products. An Engineer is a versatile mind who has an ability to build bridges between sciences, technology and society. In this world of technology it's a dream that we develop everything on our own.

 

In today's article we are going to discuss about one such innovation by the Engineers of IIT Madras making a contribution to the nation’s technological and industrial progress- Shakti India's first Microprocessor.

About Shakti

Shakti is an achievement for our country and is designed & developed by the students of IIT Madras. It is built with a microchip that is manufactured or created at ISRO (Indian Space Research Organization) Chandigarh.

This microprocessor will never get outdated as it is made with all the international standards and it is one of the few open-source microprocessors available in the world market.

Shakti" processors are based on RISC-V ISA,  It delivers the free, extensible software and hardware freedom on architecture. It is the revolutionary Processor where it laid a path to computing design and innovation for the next 50 years.

Processors of Shakti

The Base Processors:

They are classified as:

  • E – Class Processor: The E-Class processor is the embedded processor. It is mainly used to run the basic RTOS like Zephyr and eChronos which are more commonly used in sensors, robotics, and smart cards. It is an open-source IP which supports the RV 32/64 – iMac. It only supports the machine and user modes.
  • C – Class Processor: The C-Class Processor is the controller class processor that is used for the medium-range applications. This processor is highly optimized and designed with the MMU support and it runs on the operating systems like LINUX. This processor will completely support the RISC – V ISA.
  • I – class Processor:The I – Class processor is completely made with features like multi-threading, nonblocking caches, and more which are completely performance-oriented. The range of this processor is between 1.5 to 2.5 GHz.

The Multi-Core Processors:

They are classified as:

  • M – Class Processor: The M – Class Processor is designed with eight different cores that are made with both C and I class cores.
  • The S – Class Processor: The S – Class Processor is used in the Enterprises server and  Work Stations. The core of this processor is the expanded version of the I – Class processor which supports the concept of multithreading.
  • The H – Class Processor: The configuration of the H – Class Processor is SoC which is used in the Analytics workloads.  It is made with both C – Class and I – Class processors.

The Experimental Processors:

They are classified as:

  • The T – Class Processor: The T-Class processor is another type of C-Class processor which is used for object-level security.
  • The F – Class Processor: The version of fault-tolerant of the base processors is named as T – Class processors. The main features of this processor include DMR, TMR, lock-step configurations, and bus fabrics.

Importance of Shakti

  • It's unique design makes it useful in various sectors
  • Made for embedded low power wireless systems and networking systems.
  • It reduces the demand of Imported Microprocessors used in communication leading to strong security.
  • It supports digital nation and encourages more such inventions

It's our responsibility to reduce our dependency on imported products by giving useful innovations to our country like our own first Microprocessor.
