description
The TMS320C30 is the newest member of the TMS320C3x generation of DSPs from Texas Instruments (TI ).
The TMS320C30 is a 32-bit floating-point processor manufactured in 0.7-µm triple-level-metal CMOS
technology.
The TMS320C30’s internal busing and special DSP instruction set have the speed and flexibility to execute up
to 50 MFLOPS (million floating-point operations per second). The TMS320C30 optimizes speed by
implementing functions in hardware that other processors implement through software or microcode. This
hardware-intensive approach provides performance previously unavailable on a single chip.
The TMS320C30 can perform parallel multiply and ALU operations on integer or floating-point data in a single
cycle. Each processor also possesses a general-purpose register file, a program cache, dedicated ARAUs,
internal dual-access memories, one DMA channel supporting concurrent I/O, and a short machine-cycle time.
High performance and ease of use are results of these features.
General-purpose applications are enhanced greatly by the large address space, multiprocessor interface,
internally and externally generated wait states, two external interface ports, two timers, serial ports, and multiple
interrupt structure. The TMS320C30 supports a wide variety of system applications from host processor to
dedicated coprocessor.
