description

The TMSC44 DSP is a 32-bit, floating-point processor manufactured in 0.72-µm double-level-metal CMOS

technology. The TMSC44 is part of the TMS320C4x generation of DSPs from Texas Instruments. The on-chip

parallel-processing capabilities of the C44 make the immense floating-point performance required by many

applications achievable.

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.
