The SMQ320C32 is a member of the \x92320C3x generation of digital signal processors from Texas Instruments. The SMQ320C32 is an enhanced 32-bit floating-point processor manufactured in 0.7-um triple-level-metal CMOS technology. The enhancements to the \x92320C3x architecture include a variable-width external-memory interface, faster instruction cycle time, power-down modes, two-channel DMA coprocessor with configurable priorities, flexible bootloader, relocatable interrupt-vector table, and edge- or level-triggered interrupts.
The internal busing and special digital signal processing instruction set of the SMQ320C32 have the speed and flexibility to execute up to 50 million floating-point operations per second (MFLOPS). The SMQ320C32 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.
