What is DSP Processor?
DSP means:
Digital Signal Processing
Digital Signal Processor (DSP processor)
A digital signal processor (DSP) is a
specialized microprocessor with an
optimized architecture for the fast
operational needs of digital signal
processing.
SOC – System on Chip
A system on chip (SOC) is an integrated
circuit (IC) that integrates all components
of a computer or other electronic system
into a single chip.
It may contain digital, analog, mixed-
signal, and often radio-frequency
functions—all on a single chip substrate.
A typical application is in the area of
embedded systems. 4
ASIC – Application Specific
Integrated Circuit An application-specific integrated circuit
(ASIC) is an integrated circuit (IC)
customized for a particular use, rather than
intended for general-purpose use.
5
For example, a chip
designed to run in a
digital voice recorder is
an ASIC.
Embedded System
An embedded system is a computer
system designed for specific (control)
functions often with real-time computing.
Physically, embedded systems range from
portable devices such as digital watches
and MP3 players, to large stationary
installations like traffic lights or factory
controllers.

Fact 1
Many components that were once reported as “DSP chips” are no longer.
Rather, they are reported as:
Systems on chip (SoC) in categories like ASICs (Application Specific Integrated Circuit)
ASSPs (Application Specific Standard Product, as video encoding and/or decoding),
- even by traditional DSP chip vendors like Texas Instruments and Analog Devices.

Fact 2
Virtually all MCUs and MPUs have added
either:
Multiply-Accumulator (MAC) circuitry
or Single-Instruction Multiple-Data (SIMD)
circuitry
So they can also perform DSP (and often
graphics) in addition to their traditional
data processing functions.

Evidence 2
„TI visited us last month and revealed that their digital signal controller (DSC) operations based on the C2000 DSP family will no longer be reported as DSP chips.
That's because the product line is being incorporated into the
company's MCU product line.” Wireless/DSP Market Bulletin , Forward Concepts, September 4, 2008

Conclusion
The entire semiconductor market is now
driven by DSP technology, since without
DSP there would be no digital wireless, no
multimedia, no VoIP and no Internet
access of any kind.
Example – Galaxy Nexus
A touchscreen Android
smartphone developed by a
partnership between Google
and Samsung.
The Galaxy Nexus features a
dual-core 1.2 GHz TI OMAP
4460 processor (ARM Cortex-
A9) with an accompanying
PowerVR SGX540 and 1 GB of
RAM. 12
Texas Instruments OMAP44x

Package on Package Stacking
The SoC chip includes processors and
numerous digital peripherals, and comes
in a ball grid package with lower and upper
connections.
The lower balls connect to the board and
various peripherals, with the upper balls in
a ring holding the memory buses used to
access NAND flash and DDR2 RAM. 14

Summary
In todays new era of always-connected
access to the Internet and multimedia,
DSP is the underlying technology.
