CSI
CMOS Sensor Interface
The hardware block that interfaces with different image
sensor interfaces and provides a standard output that can
be used for subsequent image processing
D
DES
Data Encryption Standard
A previously predominant algorithm for the encryption of
electronic data
DLL
Delay-Locked Loop
A digital circuit similar to a phase-locked loop (PLL), with
the main difference being the absence of an internal
voltage-controlled oscillator, replaced by a delay line
DRC
Dynamic Range Compression
It reduces the volume of loud sounds or amplifies quiet
sounds by narrowing or "compressing" an audio
signal's dynamic range.
DVFS
Dynamic Voltage and Frequency Scaling
Dynamic voltage scaling is a power management
technique where the voltage used in a component is
increased or decreased, depending on circumstances.
Dynamic frequency scaling is a technique whereby the
frequency of a microprocessor can be automatically
adjusted on the fly so that the power consumption or
heat generated by the chip can be reduced. These two
are often used together to save power in mobile devices.
E
EHCI
Enhanced Host Controller Interface
The register-level interface for a Host Controller for the
USB Revision 2.0.
eMMC
Embedded Multi-Media Card
An architecture consisting of an embedded storage
solution with MMC interface, flash memory and
controller, all in a small BGA package.
F
FBGA
Fine Ball Grid Array
FBGA is based on BGA technology, but comes with
thinner contacts and is mainly used in SoC design
G
GIC
Generic Interrupt Controller
A centralized resource for supporting and managing
interrupts in a system that includes at least one processor
