  • Patent number: 6751724
    Abstract: Embodiments of the present invention relate to instruction fetching in data processing systems. One aspect involves a data processor (202) to execute instructions and to fetch instructions from a memory (208) according to a fetch size. This data processor (202) comprises a first input (212) to receive instructions, control logic (402) to decode the instructions, and an instruction pipeline (400) coupled to the first input (212) and the control logic (400). The instruction pipeline (400) is responsive to a first signal (214) to set the fetch size to one of a first size and a second size. The data processor (202) therefore allows an instruction fetch policy to be altered based on the characteristics of an accessed device in order to achieve improved performance.

  • Patent number: 6229991
    Abstract: By employing AFC range extension, a high frequency communication device (100) can use a low cost, low accuracy crystal (119) in its reference oscillator (118). AFC range extension involves varying receive bandwidth of the communication device (100) to facilitate AFC or automatic frequency control. In particular, the receive bandwidth is set to a first, wide setting for AFC acquisition purposes (208). Frequency error associated with a received AFC signal is determined (212) and receive reception is adjusted (218) to reduce frequency error in the communication device (100). Once the frequency error is below a predetermined threshold (214), the receive bandwidth is set to a second setting different from the first setting for normal reception (220).
