  2. Chisel (programming language) - Wikipedia

    en.wikipedia.org/wiki/Chisel_(programming_language)

    Chisel (an acronym for Constructing Hardware in a Scala Embedded Language [1]) is an open-source hardware description language (HDL) used to describe digital electronics and circuits at the register-transfer level. [2] [3] Chisel is based on Scala as a domain-specific language (DSL).

  3. Downsampling (signal processing) - Wikipedia

    en.wikipedia.org/wiki/Downsampling_(signal...

    Let X(f) be the Fourier transform of any function, x(t), whose samples at some interval, T, equal the x[n] sequence.Then the discrete-time Fourier transform (DTFT) is a Fourier series representation of a periodic summation of X(f): [d]

  4. Bit stuffing - Wikipedia

    en.wikipedia.org/wiki/Bit_stuffing

    The NRZI coding scheme transmits a 0 bit as a signal transition, and a 1 bit as no change. In this case, bit stuffing is most easily described as the insertion of a 0 bit after a long run of 1 bits. It was popularized by IBM's SDLC (later renamed HDLC), and is also used in Low- and full-speed USB.

  5. x86 Bit manipulation instruction set - Wikipedia

    en.wikipedia.org/wiki/X86_Bit_manipulation...

    PEXT copies selected bits from the source to contiguous low-order bits of the destination; higher-order destination bits are cleared. PDEP does the opposite for the selected bits: contiguous low-order bits are copied to selected bits of the destination; other destination bits are cleared. This can be used to extract any bitfield of the input ...

  6. Chisel - Wikipedia

    en.wikipedia.org/wiki/Chisel

    A sharp wood chisel in combination with a forstner wood drill bit is used to form this mortise for a half-lap joint in a timber frame. Parts of a wood chisel. Woodworking chisels range from small hand tools for tiny details, to large chisels used to remove big sections of wood, in 'roughing out' the shape of a pattern or design.

  7. Bitwise operation - Wikipedia

    en.wikipedia.org/wiki/Bitwise_operation

    Thus, if both bits in the compared position are 1, the bit in the resulting binary representation is 1 (1 × 1 = 1); otherwise, the result is 0 (1 × 0 = 0 and 0 × 0 = 0). For example: 0101 (decimal 5) AND 0011 (decimal 3) = 0001 (decimal 1) The operation may be used to determine whether a particular bit is set (1) or cleared (0). For example ...

  8. Deflate - Wikipedia

    en.wikipedia.org/wiki/DEFLATE

    A Deflate stream consists of a series of blocks. Each block is preceded by a 3-bit header: First bit: Last-block-in-stream marker: 1: This is the last block in the stream. 0: There are more blocks to process after this one. Second and third bits: Encoding method used for this block type:

    The following are various tools that can be used in an air hammer: [1] Universal joint and tie-rod tool Used to separate universal joints and tie-rod ends. Ball joint separator Used to separate ball joints. Shock absorber chisel Used to break loose shock absorber nuts. Exhaust pipe cutter Used to cut through exhaust pipe for disassembly ...
