description  
The TMS320C31 and TMS320LC31 DSPs are 32-bit, floating-point processors manufactured in 0.6 μm  
triple-level-metal CMOS technology. The TMS320C31 and TMS320LC31 are part of the TMS320C3x  
generation of DSPs from Texas Instruments.  
The TMS320C3x’s internal busing and special digital-signal-processing instruction set have the speed and  
flexibility to execute up to 80 million floating-point operations per second (MFLOPS). The TMS320C3x  
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 TMS320C3x 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.  
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of  
Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
