Title: Innovations of Cheng-Chi Fang
Introduction
Cheng-Chi Fang is an accomplished inventor based in Union City, California. He holds three patents that showcase his expertise in device controllers, particularly in the realm of data management and error monitoring.
Latest Patents
One of his notable inventions is the Autodisk Controller. This device controller operates in monitor mode, allowing it to track the address of incoming data blocks. When a target address is reached, it switches to buffer mode, where it can monitor various parameters and report any status or errors to a microprocessor. This innovation significantly reduces the workload on the microprocessor by handling error checks for Id errors, EDC errors, copyright errors, addressing errors, and data area errors. Additionally, the Autodisk Controller monitors the memory buffer to determine when it is full.
Another significant patent is the Autohost Controller. This device controller interfaces a host computer with an external storage device. At the end of a read operation, it fills a memory buffer with contiguous data blocks. During subsequent read operations, the Autohost Controller checks if the requested data is within the memory buffer and directs the device controller to transfer the data without needing intervention from an external microprocessor. If the Autohost Controller does not intervene, the device controller operates under the control of the microprocessor as usual.
