RXP: The Hardware Realization of High Level Interpreter

摘要

To realize the virtual machine of level 5, the Data Path of Von Neumann Machine is modified with the inclusion of analog computational blocks for processing non-binary data. For representing a number of n digits in a number system of base r_w, n voltage levels - each corresponding to a digit, are considered (polarity is used as sign). For addition signed number system and for subtraction r_w's complementation are used. Input and Output schemes similar to that of Analog to Digital Converter and Digital to Analog Converter respectively, are developed. Also scheme for noise reduction is developed including an analog to digital converter designed with one DAC and software multiplexing for multiple inputs - improved complexity than that of hardware multiplication. The vision for faster rate of data transfer and higher noise immunity could be the use of frequency modulation for data representation (band of frequencies replacing the voltage levels), data storage, data manipulation, and data transmission.
