Introduction
The DSP56F801EVM is used to demonstrate the abilities of the DSP56F801 and to
provide a hardware tool allowing the development of applications that use the
DSP56F801.
The DSP56F801EVM is an evaluation module board that includes a DSP56F801 part,
peripheral expansion connectors, external memory and a JTAG interface. The expansion
connectors are for signal monitoring and user feature expandability.
The DSP56F801EVM is designed for the following purposes:
• Allowing new users to become familiar with the features of the 56800 architecture.
The tools and examples provided with the DSP56F801EVM facilitate evaluation of
the feature set and the benefits of the family.
• Serving as a platform for real-time software development. The tool suite enables
the user to develop and simulate routines, download the software to on-chip or
on-board RAM, run it, and debug it using a debugger via the JTAG/OnCE
TM
port.
The breakpoint features of the OnCE port enable the user to easily specify complex
break conditions and to execute user-developed software at full-speed, until the
break conditions are satisfied. The ability to examine and modify all user
accessible registers, memory and peripherals through the OnCE port greatly
facilitates the task of the developer.
• Serving as a platform for hardware development. The hardware platform enables
the user to connect external hardware peripherals. The on-board peripherals can be
disabled, providing the user with the ability to reassign any and all of the DSP's
peripherals. The OnCE port's unobtrusive design means that all of the memory on
the board and on the DSP chip are available to the user.
