Latest Patents
One of Ta-Wei Chien's latest patents is focused on buffered asynchronous communications elements with receive/transmit capabilities. This invention incorporates user-selectable FIFOs as both transmitter and receiver buffers to reduce CPU interrupt overhead. The asynchronous communications element features a receiver shift register that receives serial data transfers from a communication station. Additionally, a receiver FIFO receives parallel data transfers from the receiver shift register for transfer to the CPU. A transmitter FIFO receives parallel data transfers from the CPU, while a transmitter shift register handles the serial transfer to the communications station. The design includes a transmitter time delay to eliminate multiple interrupts for a transmitter FIFO 'empty' condition already indicated to the CPU. Furthermore, programmable interrupt levels on the receiver FIFO allow for adjustments based on variable CPU latency times. A receiver time delay interrupt signals the CPU when data characters in the receiver FIFO exceed specified time limit conditions. The receiver and transmitter FIFOs can be individually and simultaneously disabled, with a single-bit register flag indicating their status.
