    Patent number: 6178476
    Abstract: Serial data processor (16) includes a digital processor (106) , a memory controller (114) interconnected with digital processor (106), and dynamic serial access memory (112) interconnected with memory controller(134) . First data selection circuit (134) sends serial data either from serial-data-in terminal (94), from dynamic serial access memory (112), or from digital processor (106) to second serial-data-in terminal (138), in response to a first control signal. Second data selection circuit (144) sends serial data either from serial-data-in terminal (138), from dynamic serial access memory (132) or from the digital processor to serial-data-out terminal (96), in response to a second control signal. A third data selection circuit (120) sends serial data either from serial-data-in terminal (94) , from dynamic serial access memory (112), or from the digital processor (90) to third serial-data-in terminal (150), in response to a third control signal.
