Technical details and manufacturing context for Result Register

Definition

The result register is a specialized memory element used in matching logic circuitry to store the output of comparison operations, pattern matching results, or logical operation outcomes. It acts as a temporary buffer that holds binary data representing the success or failure status of matching operations. This stored data enables subsequent processing stages to access and utilize the results for decision-making, control signaling, or further computational steps within digital systems. The register is typically implemented as a set of flip-flops or latches, with a storage capacity that matches the data width of the comparison logic, commonly ranging from 8 to 32 bits. It operates within a core logic supply voltage range of 1.8 to 3.3 V, as per JEDEC JESD8 standards, and is designed to meet specific input high and low voltage thresholds (0.7×VDD and 0.3×VDD, respectively). The propagation delay from clock edge to output valid is typically between 1.5 and 5.0 ns, supporting clock frequencies from 10 to 100 MHz. The register is rated for industrial temperature ranges from -40 to 85 °C during operation and -55 to 125 °C for storage, in accordance with IEC 60068-2-1/2. It has an ESD tolerance of 2000 V (HBM model) per IEC 61000-4-2. Power consumption ranges from 0.5 to 5 mW at maximum clock frequency. Common packaging includes QFN-16 (JEDEC MO-220), with a weight of 0.02 to 0.05 g depending on the package variant. The result register is fabricated using silicon, with copper and aluminum interconnects. It is essential for applications requiring rapid comparison and decision-making, such as in microprocessors, digital signal processors, and pattern recognition systems. When selecting a result register, engineers must verify that the specific model meets the required storage capacity, voltage levels, timing, and environmental specifications for their intended application.

Working Principle

The result register operates by receiving binary data inputs from matching logic comparators or processing units. When enabled by a control signal, typically a clock pulse or write enable, it latches and stores the current matching result. The stored value remains stable until the next write operation, allowing other circuit components to read the result asynchronously or synchronously. It functions as a synchronous or asynchronous storage element depending on the circuit design requirements. The register's output is available after a propagation delay, and its operation is synchronized with the system clock to ensure reliable data capture.
