摘要： A system and method for optimizing slave transaction ID width based on sparse connection between multiple masters and multiple slaves in a multilayer multilevel interconnect system-on-chip (SOC) architecture are disclosed. In one embodiment, slave transaction ID widths are computed for a first processing subsystem and a second processing subsystem including multiple masters and multiple slaves. Further, a slave transaction ID for each master to any slave in the first processing subsystem and in the second processing subsystem is generated based on the computed slave transaction ID width. Furthermore, sparse connection information between the multiple masters and multiple slaves is determined via a first bus matrix in the first processing subsystem. A first optimized slave transaction ID for each master to any slave in the first processing subsystem is then generated by removing don't care bits in each generated slave transaction ID based on the sparse connection information.

摘要： An improvement to an integrated circuit of a type having a test enable line for enabling an electrical test of the integrated circuit only when the test enable line is at a logical high value, and output lines that are only used during the electrical test of the integrated circuit, where the improvement is a switch circuit for disabling a state change in the output lines when the test enable line is at a logical low value. In this manner, the output lines do not switch during functional use of the integrated circuit, and cannot be aggressors on the data signals that are carried by the data lines that are used during the functional use of the integrated circuit. In addition, these non-switching output lines can act as guard traces that run between the data lines, further electrically isolating the data lines from one another. Further, because they do not switch during functional use of the integrated circuit, the overall power consumption of the integrated circuit is reduced.

摘要： In one embodiment, a circuit has multiple flip-flops with gated clock inputs controlled by an enable signal, where the clock signal is gated in order to reduce power consumption by the circuit. The circuit has an error detection and correction (EDC) module that is active when the enable signal is low in order to detect and correct soft errors of the flip-flops. The EDC module generates and stores an error-correction code based on the data outputs of the flip-flops. The EDC module then compares the stored error-correction code to a presently generated error-correction code, where if they are not identical, then the EDC (a) determines (i) that a soft error has occurred and (ii) which flip-flop suffered the soft error and (b) flips a corresponding error-correction signal to provide a correct corresponding output signal while the enable signal is low.
