Webdata path execute the beq instruction. Make sure your datapath can loop correctly. Non mandatory part - adding more functionality So far the datapath only implements a subset of all MIPS instructions. To support more instructions more hardware must be added to the datapath. • Extend the circuit and add support for the sll (shift logical left ... Webper instruction, which fixes some shortcomings of the 1-cycle implementation. • Faster instructions (R-type) are not held back by the slower instructions (lw, sw) • The clock cycle time can be decreased, i.e. faster clock can be used • Eventually simplifies the implementation of pipelining, the universal speed-up technique.

WebDatapath and Control . Datapath: Memory, registers, adders, ALU, and communication buses. Each step (fetch, decode, execute, save result) requires communication (data transfer) paths between memory, registers and ALU. Control: Datapath for each step is set up by control signals that set up dataflow directions on communication buses and WebA datapath is a collection of functional units such as arithmetic logic units (ALUs) or multipliers that perform data processing operations, registers, and buses.
