This LDPC software is intended as an introduction to LDPC codes computer based simulation. The pseudo-random irregular low density parity check matrix is based on Radford M. Neal’s programs collection, which can be found in [1]. While Neal’s collection is well documented, in my opinion, C source c ...

A PLD Based Delta-Sigma DAC
Delta-Sigma modulation is the simple, yet powerful,
technique responsible for the extraordinary
performance and low cost of today s audio CD
players. The simplest Delta-Sigma DAC consists of a
Delta-Sigma modulator and a one ...

Top module name : SHIFTER (File name : SHIFTER.v)
2. Input pins: SHIFT [3:0], IN [15:0], SIGN, RIGHT.
3. Output pins: OUT [15:0].
4. Input signals generated from test pattern are latched in one cycle and are
synchronized at clock rising edge.
5. The SHIFT signal describes the shift number. The shift ...

MTOOLS
version 2.0
Mtools is a public domain collection of programs to allow Unix systems
to read, write, and manipulate files on an MSDOS filesystem (typically a
diskette).
The following MSDOS commands are emulated:

The FM24C256/C256L/C256LZ devices are 256 Kbits CMOS
nonvolatile electrically erasable memory. These devices offer the
designer different low voltage and low power options. They
conform to all requirements in the Extended IIC 2-wire protocol.
Furthermore, they are designed to minimize device pin cou ...
The TMS320LF240xA and TMS320LC240xA devices, new members of the TMS320C24x generation of
digital signal processor (DSP) controllers, are part of the TMS320C2000 platform of fixed-point DSPs. The
240xA devices offer the enhanced TMS320 DSP architectural design of the C2xx core CP ...
The SL74HC573 is identical in pinout to the LS/ALS573. The device
inputs are compatible with standard CMOS outputs with pullup
resistors, they are compatible with LS/ALSTTL outputs.
These latches appear transparent to data (i.e., the outputs change
asynchronously) when Latch Enable is high. When Lat ...
