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.
