SHAKTI is a family of processors based on the RISC-V ISA and targets all the major segments of the processor spectrum, ranging from IoT class controllers to server/HPC class server parts. One of the class in series of processors, the I-Class is aimed at mobile and desktop environments. The design is highly parametrized to facilitate quick design space exploration. It is an Out-of-Order core, with pipeline depth of 8 stages, based on merged register file approach.

Another class of series of processors, the F-Class, employs ECC to tolerate errors in registers and memories and uses space and time redundancy based techniques to tolerate errors in ALU.

In this talk, we will present the design and performance characteristics of I-Class processor and fault tolerant techniques employed in ALU of the F-Class.
