Abstract
A method and system provides for increasing the throughput of serial data in a computer system when a data packet is of unknown length. The method and system includes initializing a first count register to count a length field of the data packet, the length field including a value indication of the length of the data packet. The method and system further includes storing a count for a minimum data portion in a second count register and receiving the data packet from a serial device of the computer system. The method and system further provides for transferring the length value to the RAM of the computer system and loading the count for the minimum data portion into the first count register to provide primary chaining of the first count register to the second count register. The method and system finally provides for comparing a minimum data packet length to the length value in the RAM to determine whether to utilize secondary chaining of the first count register with the second count register.
