| 20080215945 | System and method for system-on-chip interconnect verification - A system and method for verifying system-on-chip interconnect includes a first linear feedback shift register coupled to an output interface of a first system-on-chip component, a second linear feedback shift register instantiated in a second system-on-chip component, and a comparator coupled to the second linear feedback shift register and the input interface of the second system-on-chip. Another method for verifying includes generating a pseudo-random number sequence with the first linear feedback shift register and the second linear feedback shift register using an identical first initial state, and comparing an output of the first linear feedback shift register with an output of the second linear feedback shift register and reporting a miss-compare. | 09-04-2008 |
| 20080282072 | Executing Software Within Real-Time Hardware Constraints Using Functionally Programmable Branch Table - A computer system is disclosed which includes a CPU or microprocessor to drive tightly constrained hardware events. The system comprises a processor having a set of system inputs to drive a functionally programmable event, and a fast branch in the CPU including a state handler to execute instructions from the CPU to process the event. A queue in the CPU stores the events such that the non-pre-empted events are serviced in the order they are received. | 11-13-2008 |
| 20090102529 | SHIFTING INACTIVE CLOCK EDGE FOR NOISE REDUCTION - An integrated circuit and a design structure are disclosed. An integrated circuit may comprise: multiple clocked elements; a clock signal source providing clock signals to the multiple clocked elements; and a clock shifting means coupled between the clock signal source and each of the multiple clocked elements; wherein the clock shifting means shifts clock signals of the multiple clocked elements such that the clock signals of the multiple clocked elements have aligned active edges and misaligned inactive edges to reduce the clock noise generated by the inactive edges of the clock signals. | 04-23-2009 |
| 20090106724 | Transition Balancing For Noise Reduction/Di/Dt Reduction During Design, Synthesis, and Physical Design - An embodiment of a design structure is shown for noise reduction comprising synthesizing blocks of sequential latches, e.g., a pipeline circuit architecture or clocking domain, which comprises combinational logic, synthesizing a root or a master clock and at least one phase-shifted sub-domain clock for each block, assigning primary inputs and primary outputs of the block to the root clock, assigning non-primary inputs and non-primary outputs of the block to the sub-domain clock, splitting root clock inputs into root clock inputs and phase-shifted sub-domain clock inputs, assigning each of the blocks a different phase-shifted sub-domain clock phase offset, creating a clock generation circuitry for the root clocks and the phase-shifted sub-domain clocks. | 04-23-2009 |
| 20090132732 | UNIVERSAL PERIPHERAL PROCESSOR SYSTEM FOR SOC ENVIRONMENTS ON AN INTEGRATED CIRCUIT - A universal peripheral processor architecture on an integrated circuit (IC) includes first and second data buses coupled to interface logic devices for enabling communication between the first and second data buses including enabling interface of multiple signaling protocols.
