What are specification in The Digital signal controller

Which programming language is used to program? Can there use any other programming language? What is DSP and how does it work? Where are DSP and Microchip Technology similar? What are DSC devices available; describe its clock speed, PWM channels, resolution, duty cycle. How DSC is important in Diagnostics and Therapy area? What is a 16 bit digital signal controller? What type is available in 16 bit Microcontrollers? Can 16 bit digital signal controller be used in sensor processing applications? Thank you
