Abstract
Apparatus and methods for an improved priority encoder using only static circuit components. Features and aspects hereof rely exclusively on static logic circuits exclusive ROM and other memory structures as relied on in prior structures. The exemplary static circuit structures relied upon in accordance with features and aspects hereof are less susceptible to leakage current and other issues common in high density integrated circuit applications. Thus, features and aspects hereof avoid use of ROM and other similar memory devices in favor of digital encoders comprised of static logic circuits cascaded through multiplexers to provide priority encoding in digital circuit applications coupling multiple devices to a shared, common bus structure.
