Title: Method for series port materialization of cpu with high speed input/output device
Inventor: LEE KANG HO
IPC: G06F13/00
Filed: 1998-12-31
Abstract: PURPOSE: A method for series port materialization of CPU with high speed input/output device is disclosed to provide a series port that enables safe reading of data by using series port function of a high speed CPU that does not require additional hardware. CONSTITUTION: A method for series port materialization of a CPU with a high speed input/output device is composed of selection, notification, generation, conversion, and repetition. An 'Every Transition' mode is selected to measure the high speed input device's(HSI) pulse input method by the downturn edge(S410). Inputed packed data is achieved by 1 bit's start bit and 8 bit data is accomplished by 1 bit's stop bit. When the packet data is Inputted, an interrupt occurs at the downturn edge, which notifies the data input(S420). The interrupt routine designates 'Every Transition' to enable downturn edge to measure every pulse input methods(S430). Where a CAM buffer's stop bit arrives, is selected to generate a software timer interrupt(S440). By using the time of interrupt generation point, 1 bit's temporary data value is achieved(S450). When the interrupt is occurred by the high speed output device's(HSO) CAM buffer(S460), temporary data value of 1 bit is converted into 1 it of permanent data value(S470). The process is progressed to S410 and pulse input method is converted to 'Every Negative Transition' and above process is repeated.
