analog-to-digital converter (ADC)
An electronic circuit that converts continuous analog signals to discrete
digital numbers. 5, 6, 9, 13, 15, 23, 24, 29, 31, 32, 34, 36, 42, 43, 45,
46, 48
blockRAM
Random access memory integrated in Xilinx
®
FPGA in a form of mul-
tiple 18 kbit blocks. 15, 19, 36, 49
Cascaded Integrator Comb (CIC)
A discrete-time filter, which efficiently averages a large number of in-
put samples. Such filters are typically used for sampling rate changes
(decimation and interpolation). 34, 43
digital-to-analog converter (DAC)
A hardware device to convert a sequence of digital codes to correspond-
ing analog voltages or currents. 4–7, 9, 13, 15, 17, 23–25, 29, 36, 42,
47, 48, 50, 56
direct current (DC)
In electrical engineering context — a constant signal, either voltage or
current. 43
digital clock manager (DCM)
A delay-locked loop (DLL) based clock management circuit integrated
in the Xilinx
®
FPGA. The circuit allows fine phase adjustment of the
output clock relative to the input. 7, 15, 20, 23, 36, 42
delay-locked loop (DLL)
A device for managing clock skew in digital circuits. 55
