    Abstract: A microprocessor configured to detect subroutine call instructions having a target address indicative of a DSP function is provided. The detection of such instructions may be performed, for example, in an instruction decode unit within the microprocessor. Subroutine call instructions detected in this manner are routed to a digital signal processor coupled near the microprocessor or possibly integrated into the microprocessor. The microprocessor may be configured to store an indication that the DSP is enabled. If the DSP is not enabled, then the microprocessor executes the original routines stored at the target address of the instruction. Although the routines may not be as efficient in performing the DSP function, the program employing the function may still operate properly in the absence of the DSP. In this manner, a computer system may initially operate without the DSP included. If a user later decides to upgrade the computer system with a DSP, then the microprocessor may dispatch DSP functions to the DSP. Until the upgrade occurs, the microprocessor may execute the functions.

    Abstract: A serial communication system including a serial communication port structure for starting and stopping an internal clock. This internal clock is designed, in operation, to generate a clock output signal to be transmitted to a device external to the system in which the serial communication port is incorporated. By emitting a clock output pulse train of predetermined length, the serial communication port can effectively control the passage of time as sensed by the external device. The location of data boundaries relative to the clock phase is programmable such that the data boundaries coincide with active clock edges.

    Abstract: An improved vocoder system and method for estimating pitch in a speech waveform. The method comprises an improved correlation method for estimating the pitch parameter which more accurately disregards false correlation peaks resulting from the contribution of the First Formant to the pitch estimation method. The vocoder performs a correlation calculation on a frame of the speech waveform to estimate the pitch of the frame. According to the invention, during the correlation calculation the vocoder performs calculations to determine when a transition from unvoiced to voiced speech occurs. When such a transition is detected, the vocoder widens the correlation sample window. The present invention thus determines when a transition from unvoiced to voiced speech occurs and dynamically adjusts or widens the sample window to reduce the effect of the First Formant in the pitch estimation. Once this frame and the next have been classified as voiced, the correlation sample window can be reduced to its original value. Therefore, the present invention more accurately provides the correct pitch parameter in response to a sampled speech waveform.

    Abstract: A network interface transmits data packets between a host computer and a network and includes a first in first out (FIFO) buffer memory with an adaptive transmit start point determined for each data packet. The network interface receives data packets from the host computer via a peripheral component interconnect (PCI) bus. A FIFO control determines the byte length of each data packet based on the header information contained in the first few received bytes of the packet. The FIFO control also measures a minimum fill time indicating the time necessary to fill the FIFO buffer memory with a predetermined minimum amount of data necessary before transmission by the FIFO buffer memory. The FIFO control calculates the time to fill the FIFO buffer memory with each packet based on the determined length and the measured minimum fill time. The time to empty the packet from the FIFO buffer memory is also calculated based upon the length of the packet and predetermined network transmission rates. If the time to empty the packet from the FIFO buffer memory is greater than or equal to the time to fill the FIFO buffer memory, the transmit start point is set to the predetermined minimum amount; otherwise, the transmit start point is adjusted in accordance with the difference in time between filling and emptying the FIFO buffer memory with the packet, a FIFO fill rate based on the measured minimum fill time, and a coefficient that accounts for latencies in the PCI bus. The network interface thus provides an optimal transmit start point for each data packet, minimizing latency and underflow conditions during network transmission.
