† Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

NOTES: 4. All voltage values are with respect to V_SS.
            5. Actual operating power is less. This value was obtained under specially produced worst-case
                test  conditions for the TMS320C31, which are not sustained during normal device operation.
               These conditions consist of continuous parallel writes of a checkerboard pattern to both primary
               and extension buses at the maximum rate possible. See normal (I_CC) current specification in the
               electrical characteristics table and also read Calculation of TMS320C30 Power Dissipation Application
               Report (literature number SPRA020) .

The TMS320C31 and TMS320LC31 DSPs are 32-bit, floating-point processors manufactured in 0.6 mm 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.
