[🇮🇳] Vikram and Kalpana: Isro develops high-speed microprocessors for space missions

Krishna with Flute · Mar 18, 2025

ISRO is Amazing. They make all the things required inhouse. TO make cheap for specific purpose is a big big achievement. ISRO had developed Lithium Ion battery for space application which later on went into TATA vehicle making it leading EV manufacturer of the country.

Vikram and Kalpana: Isro develops high-speed microprocessors for space missions

Vikram and Kalpana: Isro develops high-speed microprocessors for space missions
The Indian Space Research Organisation (Isro) and the Semiconductor Laboratory (SCL) in Chandigarh have jointly developed two cutting-edge 32-bit microprocessors, Vikram 3201 and Kalpana 3201, specifically designed for space applications.

The first production lots of these microprocessors were handed over to Dr. V. Narayanan, Secretary, Department of Space and Chairman, Isro.

WHAT IS VIKRAM 3201?

Vikram 3201 is India's first fully indigenous 32-bit microprocessor qualified for use in the harsh conditions of launch vehicles.

A 32-bit microprocessor is a type of microprocessor with a data bus, registers, and address bus that are 32 bits wide. This means it can process 32 bits of data at a time, handle memory addresses of up to 4 GB, and execute 32-bit instructions.

It is an advanced version of the 16-bit Vikram 1601 microprocessor, which has been operational in Isro's launch vehicles since 2009.

Vikram 3201 supports floating-point computations and offers high-level language compatibility, particularly with Ada. The processor was fabricated at SCL's 180nm CMOS semiconductor fab, aligning with India's "Make in India" initiative.

WHAT IS KALPANA 3201?

Kalpana 3201 is also a 32-bit SPARC V8 RISC microprocessor based on the IEEE 1754 Instruction Set Architecture. It is designed to be compatible with open-source software toolsets and has been tested with flight software, making it versatile for various applications.

Optimized for efficiency and performance, with a focus on simple and fast instructions.

The initial lot of Vikram 3201 devices was successfully validated in space during the PSLV-C60 mission, demonstrating its reliability for future space missions. This development marks a significant milestone in achieving self-reliance in high-reliability microprocessors for launch vehicles.

In addition to the microprocessors, Isro and SCL have also developed other critical devices, including a Reconfigurable Data Acquisition System and a Multi-Channel Low Drop-out Regulator Integrated Circuit, contributing to the miniaturization of avionics systems in launch vehicles.

An MoU was signed for the development of miniaturized unsteady pressure sensors for wind tunnel applications, further enhancing collaboration between Isro and SCL.

retahrded baby steps is still better than no steps

among the highestly tightly guarded stuff hai, those lithography machines/forges etc

jo bhi bolo @Bilal9 bhai, us gangouse can into tech 😛

Sharma Ji · Mar 18, 2025

also, for space and even military apps.. old chips only they are using !

the F 22, famously, ancient software.. there's bits about it online

Sharma Ji · Mar 18, 2025

someone said something to the extent of there being more high tech nano stuff in your random mobile than there is on that fighter jet.. something like that.

makes sense even, 'if it ain't broke..'

5th gen is not a silver bullet to mil aviation blues.. wait for it, bhai.. ek Raptor bhi shot down hoga, same Buk type 70s Soviet tech gonna score a kill.

I speak to my SOC and Chip Industry friends all the time, some of them Indian. No offense - but Indian ISRO boasting about developing 32 bit SRAM chips is like an entity boasting about stone age stuff like siege weapons. It is what it is. It makes good newspaper and media copy though, for the lay Indian people who have no idea about the chip industry. Good vote-getter propaganda.

There are far better and more advanced things that India can and should boast about.

It is not about 32 bit. It is about customisation for space use and that to India specific. Many such cheapest were developed in past. One is used in Brahmos. It takes guidance from GPS, Glonas and Gagan at a time to enhance accuracy and boost redundancy.

Yawn. That Radiation-hardened-by-design (RHBD) process is also as old as the 1970's.
Next you will be telling me that Indian ISRO has developed Cassette Tape and 33 RPM records which are brand new earth-shaking technology.

What you do not understand is that the Chip technology is contemporary, but its customization makes it special for space use. Even lower computing speed chips are made for washing machines and other home appliances as they work batter for specific purpose. This is not a rocket science.

Welcome to 2013 when $2 per piece Android phone (SOC) chips mounted on a cheap Android phone were sent to space.

Whether these 32 bit SRAM Indian chips work "batter" for specific purpose (space) is debatable. They are - in real terms, stone age technology made in India.

Instead of coming up with stories yourself (none are engineers here that I can see) - go ask one of the Indian electrical engineers who will know better.

Many chips in Washing machines, Automobiles and other appliances are very law in processing power. However, because of the customized programming, they work beautifully for particular sort of functioning because they are specifically made for that. Making application specific Chip is a very common development in industries, aviation and space. There are chips which are specifically made for aviation and make aviation single chip possible. However, those who has decided to find fault are beyond repair.

Then you must be knowing Vinod Dham, an Indian who made first Pentium Chip. Indians made it in US so Indians can make it here as well. Our well-wishers in Bangladesh and Pakistan thinks that we cannot make it but in past those who had thought that India cannot make it are proved each and every time. When US denied India supercomputer CRY XMP, Rajiv Gandhi established C-DAC and entrusted Vijay Bhatkar to make supercomputer. In a short span of time with 10 time faster supercomputer. We are on the verge of becoming a big player in Chip manufacturing like mobile. A decade back, we had 2 mobile companies. Today our mobile export is about 23 BN USD.
