Abstract: Methods and apparatus for utilization of preset evaluation to improve input/output performance in high-speed serial interconnects are described. In some embodiments, performance of a link is evaluated at a plurality of equalization values and one of the plurality of equalization values is selected for the link based on comparison of a plurality of margin values that are to be determined for each of the plurality of equalization values. Other embodiments are also claimed and/or disclosed.

Abstract: Methods and apparatus for provision of equalization effort-balancing of transmit (TX) Finite Impulse Response (FIR) and receive (RX) Linear Equalizer (LE) or RX Decision Feedback Equalizer (DFE) structures in high-speed serial interconnects are described. In some embodiments, data corresponding to a plurality of transmit equalization values and a plurality of receive equalization values for each lane of a link having a plurality of lanes is detected. At least one of the plurality of the transmit equalization values and at least one of the plurality of the receive equalization values are selected for each lane of the plurality of lanes of the link based on detection of saturation in a Decision Feedback Equalizer (DFE) tap of a corresponding lane of the link. Other embodiments are also claimed and/or disclosed.

Abstract: A cache memory data compression and decompression technique is described. A processor device includes a memory controller unit (MCU) coupled to a main memory and a cache memory. The MCU includes a cache memory data compression and decompression module that compresses data received from the main memory. The compressed data may then be stored in the cache memory. The cache memory data compression and decompression module may also decompress data that is stored in the cache memory. For example, in response to a cache hit for data requested by a processor, the compressed data in the cache memory may be decompressed and subsequently read or operated upon by the processor.
