摘要： A method for reducing logic and delay within a logic structure that includes searching logic structures to be analyzed, finding a plurality of latches within a logic structure to be analyzed, determining if any respective latches of the plurality of latches have sufficiently positive slack within an input and output path thereof and optionally excluding the respective latches from being analyzed, determining if there is at least one remaining latch to be analyzed, and determining whether inverters are disposed within an input path and an output path of the at least one remaining latch. The method further includes obtaining logic functions of the input path and output path of the at least one remaining latch when inverters are found, modifying the logic functions using DeMorgan's Theorems, determining whether timing violations exist with the modified logic functions, and annotating hardware description language based on the modified logic functions when no timing violations exist.

摘要： A system and method in which the receiving chip separately latches each half of the data received from the double data rate bus. Each half is launched as soon as it is available; one on the normal chip cycle time and the other is launched from a Master (L1) latch a half cycle into the normal chip cycle time. The first launched half of the data proceeds through the chip along its standard design chip path to be captured by the chips driving interface latch and launched again after one cycle of latency on the chip. The second half of the data proceeds through the chip one half cycle behind the first half, and is latched a half clock cycle later part way through the path into a Slave (L2) latch. On the next edge of the local clock, the data then continues from the L2 latch to the driving double data rate interface. This allows a half cycle set up time for the second half of the data so that it can be launched again, maintaining a one-cycle time on the chip.

摘要： A double data rate launch system and method in which the two-to-one multiplexer select signal delay is programmable and can be adjusted individually for each system. This allows the amount of delay to be minimized based on the actual set up time required, not the worst-case set-up time. The select signal to the multiplexer is delayed sufficiently to compensate for non-uniformity of duty cycle of data at the inputs to the multiplexer. Compensation of the non-uniformity allows the data on the wire to have a uniform duty cycle for all data transferred regardless of which latch is sourcing the data. The multiplexer that selects data from the two latches which are launching data on the edge of different clocks has a select line that is delayed by a variable amount to tune the select such that the data is clean at the input to the multiplexer on all ports.

摘要： A method and hardware design is disclosed for allowing the bring-up of a large scale system of interfaces that need to undergo a sequence of calibration steps. The method involves the use of a flexible broadcast scheme whereby groups of interfaces within a chip are assigned to groups to which commands can be broadcast. The scheme allows for the maximum amount of flexibility, allowing interfaces to be assigned to multiple groups which can overlap and be subsets of one another, and still allows for groups to be excluded from broadcast commands and be access individually. A method is also disclosed for using a chip-global status summary that can be accessed as any other register on the chip and can report calibration results for an entire chip with only one command. According to the invention a service utilizing the method embodied with code for implementing the method can now be provided.

摘要： A method of calibrating an elastic interface is provided to automatically achieve a minimal cycle delay through the interface. An existing self-alignment interface (i.e. elastic interface) is used to de-skew within a cycle and stage the data to have it arrive on a given, programmed target cycle. However, this target cycle must be calculated in advance and may be larger than it needs to be, causing more latency on the interface. This method is used to determine the earliest target cycle (with or without additional guard-band). This target cycle is used to adjust the interface automatically to achieve this earliest target cycle. The determination of earliest target cycle can be done once, continuously, or using a sample window. The method also can be used for interfaces that have frequency multipliers or phase shifts at its boundaries.

摘要： The culture of microorganisms endogenous to plants is a process for increasing the number of such microorganisms and collecting the enriched culture media for nutritional, pharmaceutical and cosmetic use. The process includes the steps of: (a) separating plant components (e.g., leaves, fruit, etc.) into smaller parts; (b) immersing the smaller plant parts in a culture medium of an aqueous solution of sodium chloride and sucrose; (c) permitting the immersed parts to stand in the culture medium for between about 7-14 days; (d) removing the smaller plant parts from the culture medium; (e) dividing the culture medium into two portions; (f) diluting each of the portions 1:2 with water; (g) permitting the diluted portions to stand between about 7-14 days to ferment; (h) filtering the diluted portions; and (i) collecting the supernatant. Steps (e) through (g) may be repeated as often as desired. The process may also include maintaining the concentration of sucrose.

摘要： A double data rate interface in which the set-up interval is extended for a data path in which data is delayed relative to the other data path. Data is latched into a register comprised of mid cycle type latches, such as for example L2* latches. For example, if the delayed half of the data is not available until the second half of the double data rate cycle, the second half of the data is allowed to have a set-up interval around the mid cycle point while the on-chip timing logic launches the least delayed half of the data on the clock edge after it is set up, without waiting for the expiration of the set up interval of the delayed data.
