Abstract
It needs a circuit between the digital circuit and the analog circuit to make the serial data become the parallel data. So I based on the theory of Serial Peripheral Interface Bus to design the circuit. And to introduce the block diagram, finite state machine, and timing diagram. Then show the IC design flow, like synthesis, pre-simulation, APR, and post-simulation. Finally the circuit can make the serial data become the parallel data. Medicine warehousing flow made in web pages can save a lot of time and papers. And the data are more reliable. According to the user’s requirements, I can design the medicine warehousing flow and the web pages of the flow. By using the upload files, barcode machine, and automatic check of the web pages, the web pages can help the users very well.
