description (continued)
The TMS370Cx9x family provides the system designer with very economical, efficient solutions to real-time
control applications. The TMS370 family compact development tool (CDT™) solves the challenge of efficiently
developing the software and hardware required to design the TMS370Cx9x into an ever-increasing number of
complex applications. The application source code can be written in assembly and C-language, and the output
code can be generated by the linker. The TMS370 family CDT development tool can communicate through a
standard RS-232-C interface with a personal computer. This allows the use of personal-computer editors and
software utilities already familiar to the designer. The TMS370 family CDT emphasizes ease-of-use through
extensive use of menus and screen windowing so that a system designer with minimal training can begin
developing software. Precise real-time in-circuit emulation and extensive symbolic debug and analysis tools
ensure efficient software and hardware implementation as well as reduced time-to-market cycle.
The TMS370Cx9x family together with the TMS370 family CDT370 PACT, software tools, the SE370C792
reprogrammable device, comprehensive product documentation, and customer support provide a complete
solution to the needs of the system designer.
CPU
The CPU used on TMS370Cx9x devices is the high-performance 8-bit TMS370 CPU module. The ’x9x
implements an efficient register-to-register architecture that eliminates the conventional accumulator
bottleneck. The complete ’x9x instruction set is summarized in Table 21. Figure 1 illustrates the CPU registers
and memory blocks.
