Abstract: Compressing data includes hashing a first token length of an incoming data steam into a hash table, where the first token length includes a plurality of bytes. A second token length of the incoming data stream may be hashed into the hash table. The second token may be larger than the first token length and includes the plurality of bytes. The method may further include automatically comparing which token length enabled more efficient data compression, and automatically adjusting at least one of the first and second token lengths based on the comparison.

Abstract: A trace assist unit operable with a plurality of processor cores is described. The trace assist unit comprises a plurality of physical buffers, and loading circuitry and unloading circuitry that are communicatively coupled with the plurality of physical buffers. The loading circuitry receives trace events from various ones of the plurality of processor cores, each of the trace events having a respective category from a plurality of predefined categories. The loading circuitry writes the trace events to respective ones of the plurality of physical buffers that are assigned to the respective categories of the plurality of predefined categories. The loading circuitry transmits, responsive to one or more predefined conditions, an unload signal to the unloading circuitry to unload contents of a selected physical buffer of the plurality of physical buffers to an external memory.
