Shakti – C Class Processor

Shakti - C Class Processor

C Class : The C Class is a controller class of processors, aimed at mid-range application workloads. The core is a highly optimized, 5-stage in-order design with MMU support and capability to run operating systems Linux and Sel4. These processors are targeted at compute/control applications in the 0.5-1.5 Ghz range. The C-class will supports the full RISC-V ISA. The C Class is also the basis for our Tagged-ISA and Fault tolerant cores.


Architectural Features

Overview :

  • An in-order 5-stage 64-bit microcontroller supporting the entire stable RISC-V ISA.
  • Targets mid-range compute systems: 200-800MHz (can be customized for 2 Ghz applications)
  • Supports RISC-V Linux, secure L4
  • Variants for low-power and high-performance.
  • Positioned against ARM’s Cortex A35/A55.
