A configurable 32 or 64-bit RISC-V core called Zilla has been designed, verified, and validated on FPGA in-house at Vivartan.

Research Programs

Promotion of Research and Development through incubation centers at engineering colleges in Mysore and Bangalore.

Achievements

Publications, implementation of working processors, & making graduates industry-ready through VLSI training & real-world projects.

Introducing Zilla RISC-V Core

Vivartan proudly introduces Zilla, our in-house developed RISC-V based processor core. Zilla represents a significant step in India’s journey toward self-reliance in semiconductor technology. Built from the ground up by our engineers, Zilla is designed to deliver flexibility, scalability, and performance across a wide range of applications.

  • Based on Open-Source RISC-V ISA – ensuring extensibility and community-driven evolution.
  • Configurable 32-bit or 64-bit datapath – adaptable to diverse use cases.
  • Instruction Set Support – Integer (I), Multiply/Divide (M), and custom instructions.
  • Custom Multiplier and Divider Units – optimized for performance.
  • Five-Stage Pipeline Architecture – balancing throughput and efficiency.
  • AXI-4 Lite Memory Interface – seamless data and instruction access.
  • Integrated Debug Module – compliant with RISC-V debug specifications.
