RISC processors can be used to face the ever increasing demand for performance required by embedded systems. Nevertheless, this solution comes with the cost of poor code density. Alternative encodings for instruction sets, such as MIPS16 and Thumb, represent an effective approach to deal with this drawback. This article proposes to apply a new encoding to(More)
Microprocessor manufacturers typically keep old instruction sets in modern processors to ensure backward compatibility with legacy software. The introduction of newer extensions to the ISA increases the design complexity of microprocessor front-ends, exacerbates the consumption of precious on-chip resources (e.g., silicon area and energy), and demands more(More)
Natural methods of fertility regulation are acceptable in most cultures. Many couples worldwide do not wish to use contraceptives or do not have access to them but wish to limit their family size or lengthen the time between births. Barriers to expanding use of natural family planning (NFP) methods include a lack of providers who can teach NFP and a lack of(More)
