Abstract
An integrated circuit coupled to an external serial bus is presented. A method for prefetching data from an external serial bus is presented. The integrated circuit comprises a serial interface, a data cache, and a prefetch control unit. The serial interface detects a data address on the serial bus and reads data elements from data storage units. The data storage units may be internal or external to the integrated circuit. The data cache is coupled to the serial interface via an internal bus. The prefetch control unit instructs the serial interface to prefetch a data element associated with the data address by reading the data element from a target data storage unit associated with the data address. The data element and the data address are written to the data cache. When a read request is detected, the data element can be quickly accessed from the data cache.
