description
The TMS320C32 is the newest member of the TMS320C3x generation of digital signal processors ( DSPs) from
Texas Instruments. The TMS320C32 is an enhanced 32-bit floating-point processor manufactured in 0.7-µm
triple-level-metal CMOS technology. The enhancements to the TMS320C3x architecture include a
variable-width external-memory interface, faster instruction cycle time, power-down modes, two-channel DMA
coprocessor with configurable priorities, flexible boot loader, relocatable interrupt-vector table, and edge- or
level-triggered interrupts.
