Abstract
A processor includes a register file and an execution unit. The execution unit includes a hash circuit including at least a state register, a state update circuit coupled to the state register, and a control circuit. Based on a hash instruction, the hash circuit receives from the register file and buffers within the state register a current state of a message being hashed. The state update circuit performs state update function on contents of the state register, where performing the state update function includes performing a plurality of iterative rounds of processing on contents of the state register and returning a result of each of the plurality of iterative rounds of processing to the state register. Following completion of all of the plurality of iterative rounds of processing, the execution unit stores contents of the state register to the register file as an updated state of the message.
