Abstract
The invention relates to a command controller and a prefetch buffer, and in particular, to a command controller and a prefetch buffer for accessing a serial flash in an embedded system. An embedded system comprises a serial flash, a processor, a plurality of access devices, and a prefetch buffer. The processor and the plurality of access devices send various commands to read data from or write data to the serial flash. The prefetch buffer temporarily stores a predetermined amount of data before data being read from or written to the serial flash.
