The purpose of DSP and MAC integrated to MCU, like 16 bits MCU ST10F276 and it's special applications.

ST10F276 ( 144 pins, 512 Byte Flash, 320K Byte Xflash) has integrated with DSP and MAC, what the purpose of it? any special application for such configuration? which STM 32 bits MCU have same construction? thanks.

The purpose of a hardware Digital Signal Processor (DSP)/MAC is to free up the CPU while data gets processed. It's to process signals.
Most (all?) STM32 chips do not have (or need) a dedicated hardware DSP as the clock speed is fast enough to perform these functions without requiring too much CPU power. Most of them have a single cycle multiply and accumulate (MAC) instruction, which makes DSP functions particularly efficient.
