A digital signal processor (DSP) is a specialized microprocessor chip, with its architecture optimized for the operational needs of digital signal processing. [ 1 ] : 104–107 [ 2 ] DSPs are fabricated on metal–oxide–semiconductor (MOS) integrated circuit chips.
The DSP56000 uses fixed-point arithmetic, with 24-bit program words and 24-bit data words. It includes two 24-bit registers , which can also be referred to as a single 48-bit register. It also includes two 56-bit accumulators , each with an 8-bit "extension" ( a.k.a. headroom); otherwise, the accumulators are similar to the other 24/48-bit ...
According to 2012 estimation, Qualcomm shipped 1.2 billion DSP cores inside its system on a chip (SoCs) (average 2.3 DSP core per SoC) in 2011, and 1.5 billion cores were planned for 2012, making the QDSP6 the most shipped architecture of DSP [12] (CEVA had around 1 billion of DSP cores shipped in 2011 with 90% of IP-licensable DSP market [13]).
The Texas Instruments DaVinci is a family of system on a chip processors that are primarily used in embedded video and vision applications. [1] [2] Many processors in the family combine a DSP core based on the TMS320 C6000 VLIW DSP family and an ARM CPU core into a single system on chip.
Blackfin is a family of 16-/32-bit microprocessors developed, manufactured and marketed by Analog Devices.The processors have built-in, fixed-point digital signal processor (DSP) functionality performed by 16-bit multiply–accumulates (MACs), accompanied on-chip by a microcontroller. [1]

The U.S. Preventive Services Task Force released a draft recommendation advising against using vitamin D to prevent falls and fractures in people over 60. Pharmacist Katy Dubinsky weighs in.
A digital signal controller (DSC) is a hybrid of microcontrollers and digital signal processors (DSPs). Like microcontrollers, DSCs have fast interrupt responses, offer control-oriented peripherals like PWMs and watchdog timers, and are usually programmed using the C programming language, although they can be programmed using the device's native assembly language.
