Abstract: A method and system of modularized design for a microprocessor are disclosed. Embodiments disclose modularization techniques, whereby the overall design of the execution unit of the processor is split into different functional modules. The modules are configured to function independent of each other. The microprocessor comprises different components such as a cache logic (201), a clock generation unit (202), a dispatcher (203), a special asynchronous interface (204), an interrupt unit (205), a register file (206) and a multiplexer unit (207). Temporary storage of data in the register files is eliminated, and thus data fetch latency is eliminated. The asynchronous transfer triggered execution architecture increases speed of execution.
