摘要： A computation efficient polyphase channelization system enables one of many user FDMA signals to be channelized through multiple FFT response frequency bands forming an aggregate frequency band where K-point FFT channels are greater than the decimation factor M to produce FFT overlapped responses that have a smooth aggregate response without disjointed band gaps for reduced distortion using a clockwise commutator having M channels feeding M filter blocks, each of which having β polyphase filters, and having a ring switch to provide smooth filter responses that then drive β K-point FFTs to provide a β set of K vector FFT responses that are then combined in a post processing system for producing K channelized outputs.

摘要： A method of operating a data processing system having a main memory divided into memory pages that are swapped into and out of main memory when the main memory becomes short. The data processing system has an operating system that sends page store commands specifying memory pages to be stored in a swap file and page retrieve commands specifying memory pages to be retrieved from the swap file and stored in the main memory. The present invention provides a swap driver that utilizes compression code for converting one of the memory pages that is to be swapped out of main memory to a compressed memory page. The data processing memory includes a compressed page region that is used to store the compressed memory pages. A page table in the compressed page region specifies the location of each compressed page and the page address corresponding to that page. The swap driver compresses at least one of the memory pages specified in one of the page store commands to provide a corresponding compressed memory page and causes that compressed memory page to be stored in the compressed page region. The swap driver also searches the page table for a page identified in one of the retrieve commands. The swap driver causes that page to be moved to a corresponding area of main memory after decompressing the page if the swap driver finds an entry in the page table indicating that the page is stored in the compressed page region.

摘要： To support speculative execution in a processor, a speculative look aside table stores information about deferred exceptions. Labels attached to predicates in the predicate register file of the processor serve as indices to a speculative look aside table. When an exception is generated for a speculative operation, the speculative look aside table is updated. Deferred exceptions are detected and handled when the processor reads the corresponding entry in the speculative look aside table during an explicit or implicit check operation.
