  • Patent number: 7027539
    Abstract: A wireless communication device processes N Radio Frequency (RF) bursts contained within N slots of a digital communications time divided frame, wherein N is a positive integer greater than one. The wireless communication device includes an RF front end, a baseband processor, and an equalizer module. The RF from end is operable to receive the plurality of received RF bursts and to convert the RF bursts to corresponding baseband signals. The baseband processor operably couples to the RF front end, is operable to receive the baseband signals, is operable to pre-equalization process the baseband signals to produce processed baseband signals, and is operable to post-equalization process soft decisions. The equalizer module operably couples to the baseband processor and is operable to equalize the processed baseband signals to produce the soft decisions. These RF bursts may be contained in adjacent slots or, in non-adjacent slots, or in a combination of adjacent slots and non-adjacent slots.

  • Publication number: 20050273589
    Abstract: A method and system is provided for efficient execution of code in memory by a processing device and may comprise determining whether a first type of memory is present. If the first type of memory is present, at least a portion of code stored in the first type of memory may be copied to a second type of memory and executed in the latter. The first type of memory may be NAND flash memory and the second type of memory may be SDRAM. A loader image may be copied from the first type of memory to an instruction memory and a jump made to the entry of the copied loader image. Code for the loader image may then be executed. Vectors may also be copied from the first type of memory to the instruction memory and mapped to a startup address.
