Abstract
A digital electronics system for generating pulses from a series of data words incluidng RAM lookup tables for translating the series of data words into a series of pulse attribute words, where each pulse attribute word includes information for controlling the formation of a corresponding pulse, multiplexers for splitting the series of pulse attribute words into two channels, pulse forming circuits corresponding to each channel for accepting pulse attribute words from respective channels and forming pulses using the information included in the pulse attribute words, and control circuits for generating the pulses, where a pulse from a first pulse forming circuit is generated while a pulse from a second pulse forming circuit is being formed.
Claims15
A digital electronics system for generating pulses from a series of data words comprising:
- means for translating the series of data words into a series of pulse attribute words, wherein each of said pulse attribute words includes information for controlling a formation of a corresponding pulse;
- means for splitting the series of pulse attribute words into two channels;
- means corresponding to each channel and accepting pulse attribute words from respective channels, for forming pulses using the information included in the pulse attribute words for controlling the formation of the pulses;
- and
- means for generating the pulses, wherein a first pulse is generated while a second pulse is being formed by the forming means.
In a digital electronics system, a method for generating pulses from a series of data words, wherein the method comprises the following steps:
- translating the series of data words into two series of pulse attribute words wherein each of said pulse attribute words includes information for controlling a formation of a corresponding pulse;
- splitting each series of pulse attribute words into two channels;
- accepting pulse attribute words from respective channels;
- forming pulses, using the information included in the pulse attribute words for controlling formation of the pulses;
- and
- generating pulses, wherein a first pulse is generated while a second pulse is being formed.
