Abstract:
Various embodiments of the present invention provide circuits and methods for improved virus processing. As one example, such methods may include providing a system memory, a general purpose processor and a virus co-processor. The methods further include receiving a data segment at the general purpose processor, and storing the data segment to the system memory using virtual addresses. The data segment is accessed from the system memory by the virus co-processor using the virtual addresses. The virus co-processor then scans the data segment for viruses and returns a result.
Abstract:
An OFDM receiver has a DC offset estimator configured for determining a DC offset, in I and Q components of a received OFDM signal having been output by an analog front end, based on filtering prescribed subcarrier components from a preamble segment of the I and Q components. The OFDM receiver removes the determined DC offset from the I and Q components, resulting in respective corrected I and Q components having minimal DC offset.
Abstract:
Circuits and methods for detecting, identifying and/or removing undesired content are provided. According to one embodiment, a method for virus processing is provided. A general purpose processor receives and stores a data segment to a first memory at a virtual address. The first memory contains paging data structures for translating virtual addresses to physical addresses. The general purpose processor directs a virus processing hardware accelerator to scan the data segment based on virus signatures compiled for the virus processing hardware accelerator and stored in a second memory. The first memory includes a first virus signature compiled for the general purpose processor. The virus processing hardware accelerator retrieves the data segment by accessing the first memory based on the virtual address and cached information, stored within one or more translation lookaside buffers local to the virus processing hardware accelerator, relating to most recently used entries of the paging data structures.

Abstract:
Methods and systems for a more efficient transmission of network traffic are provided. According to one embodiment, a method is provided for performing segmentation offloading, such as TCP segmentation offloading (TSO). An interface performs direct virtual memory addressing of a user memory space of a system memory on behalf of a network processor to fetch payload data originated by a user process running on a host processor. Then, the network processor segments the payload data across one or more packets.

Abstract:
An OFDM receiver has an autocorrelation circuit configured for generating autocorrelated power values from samples of received short preamble symbols in a received data packet, and a median filter configured for generating a median autocorrelation value from at least a prescribed minimum number of the autocorrelated signal values. A comparator is configured for detecting a symbol boundary, identifying an end of the short preamble symbols, based on the autocorrelated signal values falling below a threshold that is based on the median autocorrelation value. Hence, the threshold used to identify the symbol boundary is dynamically calculated on a per-packet basis, eliminating errors due to varying energy levels or propagation characteristics from different packet sources; moreover, the median autocorrelation value minimizes effects due to noise components, minimizing false detection errors.
Abstract:
An OFDM receiver configured for measuring frequency error based on comparing prescribed pilot tones from a prescribed group of consecutive symbols in a received OFDM signal. A complex conjugate generator is configured for generating complex conjugates of the prescribed pilot tones of a first subgroup of the consecutive symbols. A multiplier is configured for generating a complex pilot product, for each symbol subgroup position, by multiplying the pilot tones of a second subgroup symbol at the corresponding symbol subgroup position with the respective complex conjugates of the first subgroup symbol at the corresponding symbol subgroup position. A complex summation circuit sums the complex pilot products of the symbol subgroup positions to obtain an accumulated complex value. A error calculator calculates the frequency error from the accumulated complex value for use in correcting frequency offset.
