Mirafra Technologies, a Bengaluru, India-based semiconductor design services company, has developed and taped out a 22-nm SoC called Ramanujan. The project is part of an internal effort to provide full end-to-end silicon delivery capability, rather than an attempt to enter the merchant chip market.
In an exclusive conversation with EE Times, Alok Kuchlous, co-founder and CEO of Mirafra, said the chip is intended as a demonstration vehicle to show that an Indian services firm can take responsibility for an entire SoC program—from architecture definition through physical design, software bring-up, and lab validation.
Chip architecture and design
Ramanujan is built around a dual network-on-chip (NoC) architecture that separates application processing from secure boot and system control functions, while allowing AXI-based (Advanced eXtensible Interface) communication between the two domains. The SoC integrates a single-core Arm Cortex-A55 application processor alongside a separate InCore RISC-V Azurite core for system and secure functions. The SoC supports external memory through SDRAM, Flash, and HyperRAM interfaces, along with on-chip SRAM and standard DMA-based data movement.
