Patent ID: 8433543

Claim:
A digital oscilloscope with glitch detection, comprising: a synchronous random access memory (RAM); a digital signal processing unit, coupled to the synchronous RAM, including: an analog-to-digital (A/D) converter to digitize an analog signal; and a digital signal processor, including: a dual-port RAM; a plurality of processing blocks to process the digitized analog signal data, detect glitches in the digitized analog signal data, store the processed signal data in the synchronous RAM, create display data from the stored signal data, and store the display data in the dual-port RAM; and a communications interface to transmit the stored display data; and a master control unit, coupled to the digital signal processing unit, including: an internal communications interface coupled to the digital signal processing unit communications interface; an external communications interface; and a central processing unit to receive the display data over the internal communications interface and transmit the display data over the external communications interface.
