    摘要: A MEMS component is monitored to determine its status. Sensors are deployed to sense the MEMS component and produce detection signals that are analyzed to determine the MEMS component state. An indicator device alerts a user of the status, particularly if the MEMS component has failed. Additionally, the MEMS component monitoring system may be practiced as a design structure encoded on computer readable storage media as part of a circuit design system.

    摘要: In connection with a logic circuit including a mask generator for determining a value for a so-called "sticky bit" in a binary number to be truncated and rounded, an intermediate signal is taken from the mask generator and an Exclusive-OR function applied to adjacent bits to generate a second mask containing or adjacent to a transition between the portion of the number to be dropped and the portion to be retained in the truncated number. The second mask is applied to different overlapping groups of bits in a portion of the number which contains the least significant bit and the guard bit as determined from the number of bits to be dropped, for example, by shifting out from a shifter, as the number is truncated and rounded to extract a specific bit in each group of bits. By extracting such specific bits using a mask, the extraction process is removed from the critical path of the processor which includes the shifter and the extraction process can proceed in parallel with the shifting process.

    摘要: An effective address limit checker reduces the logic delay in the limit checking path. The address limit checker comprises an effective address (EA) adder and limit check logic. The EA adder includes a first carry save adder receiving a displacement, an index and a base address for calculating an effective address, and a second carry select adder receiving partial sum and carry outputs of said first adder for calculating an effective address carry out. The outputs of the EA adder are input to the limit checking logic together with an address limit value and an addressability mode field. The limit checking logic includes a third adder for calculating first partial limit information based on the first adder results and the limit value, and a fourth adder for calculating second partial limit information based on the first adder results and the limit value and conditioned carry out values of the third adder. The third and fourth adders are each composed of a carry save adder and a carry select adder. Conditional carry logic responsive to output values of the third adder controls the operation of the fourth adder based on the addressability mode field. Limit exceeded logic responsive to the carry out of the fourth adder and the second adder asserts a limit check condition.
