Publication number: 20150379175Abstract: An updated integrated circuit (IC) design is generated by applying a histogram-based algorithm to an invalid, current IC design. The histogram-based algorithm includes worst negative slack (WNS) optimization followed by total negative slack (TNS) optimization. WNS optimization uses the slack histogram for the current IC design to generate an invalid, but improved, intermediate IC design. TNS optimization uses the slack histogram of the intermediate IC design to generate the updated IC design.Type: ApplicationFiled: June 30, 2014Publication date: December 31, 2015Applicant: Freescale Semiconductor, Inc.Inventors: Mohit Parnami, Sorabh Sachdeva

Publication number: 20150379181Abstract: This disclosure describes a multi-height routing cell and utilization of the multi-height routing in an integrated circuit to reduce routing congestion in a standard cell design floorplan. The multi-height routing cell includes a bypass connection, or “tunnel,” that routes a signal through a non-routing layer and under an impeding power rail. The multi-height routing cell includes bypass connectors on both sides of the bypass connection that provide connection points for which to connect standard cells on opposite sides of the impeding power rail. As such, the multi-height routing cell provides a route underneath the impeding power rail and, in turn, reducing routing congestion in the standard cell design floorplan.Type: ApplicationFiled: September 2, 2015Publication date: December 31, 2015Applicant: FREESCALE SEMICONDUCTOR, INC.Inventors: Colin Macdonald, Anis M.

Publication number: 20150379971Abstract: A display processor device is for processing display image data by overlaying a multitude of image layers. Pixel values of at least one of the image layers are stored in a memory and may comprise pixels values having a single predefined value, such as transparency. The display processor has a fetch unit for selectively fetching stored pixel values from the memory by skipping stored pixels values having the single predefined value according to a fetch mask indicative of pixels values having the single predetermined value. Advantageously the bandwidth for accessing the memory is reduced, because less pixel data values need be retrieved. Power consumption may be reduced, and slower memories may be applied.Type: ApplicationFiled: February 12, 2013Publication date: December 31, 2015Applicant: Freescale Semiconductor, Inc.Inventors: Michael STAUDENMAIER, Vincent AUBINEAU, Anton ROZEN

Publication number: 20150382316Abstract: A method of searching of base stations in a mobile communication system has a first stage of detecting at least one slot boundary, a second stage of detecting at least one frame boundary and a scrambling code group, and a third stage of detecting a scrambling code. Multiple possible base stations are identified by determining a first threshold based on correlation values of correlating the input signal with a primary synchronization channel code. For each hit, the input signal is aligned to the corresponding slot boundary, an average correlation value is based on all correlations with secondary sequences, and a second threshold based on the average correlation value is set. Any delay and codewords that have a correlation value above the second threshold are correlated with the codes in the detected group so as to determine multiple base stations.Type: ApplicationFiled: February 15, 2013Publication date: December 31, 2015Applicant: Freescale Semiconductor, Inc.Inventors: Tudor BOGATU, Lucian PANDURU

Publication number: 20150380067Abstract: A system provides synchronous read data sampling between a memory and a memory controller, which includes an asynchronous FIFO buffer and which outputs a clock and other control signals. An outbound control signal (e.g., read_enable) is used to time-stamp the beginning of a read access using a clock edge counter. The incoming read data is qualified based on the time-stamped value of the read_enable signal plus typical access latency by counting FIFO pops. The system performs correct data sampling irrespective of propagation delays between the controller and memory. The system may be implemented in a System on a Chip (SOC) device having a synchronous communication system.Type: ApplicationFiled: June 29, 2014Publication date: December 31, 2015Applicant: Freescale Semiconductor, Inc.Inventors: Prabhjot Singh, Hemant Nautiyal, Amit Rao
