Universal Command Converter
Motorola
General Description
uses a dedicated OnCE serial port to access the internal module. In other Motorola DSPs,
the internal OnCE module is addressed using the IEEE Joint Test Action Group (JTAG)
four-wire test access port (TAP) boundary scan architecture protocol. The tools software
can use either the direct OnCE serial port or the JTAG serial port.
This manual describes the installation, use, and functional description of the control
system that interacts with the target DSP.
1.1 General Description
The ADS is a tool for designing, debugging, and evaluating DSP-based systems. It
consists of three hardware circuit boards, as illustrated in Figure 1-1, and two software
programs. The hardware circuit boards are the host-bus interface, the command converter,
and the ADM. The two software programs are the ADS user interface program, which is
executed on the host computer, and the command converter monitor program which is
expected on the command converter. Figure 1-1 illustrates the ADS being used as a
hardware evaluation tool or host software accelerator. The ADM card has a 14-pin
connector, which provides an access point for the command converter JTAG/OnCE
interface.
