| FIR filter | By Quotes | None | 300 MHz | None |  |
|
| FIR_F is an FIR filter implementation designed for very high sample rate applications. Organized as a systolic array the filter is modular and fully scalable, permitting the user to specify large order filters without compromising maximum attainable clock-speed. Mathematically, the filter implements the difference equation: y[n] = h0 x[n] + h1 x[n−1] + ... + hN x[n−N ] In the above equation, the input signal is x[n], the output signal is y[n] and h0 to hN represent the filter coefficients. The number N is the filter order, the number of filter taps being equal to N+1. Application General purpose FIR filters with odd or even numbers of taps Filters with arbitrary sets of coefficients Very high-speed filtering applications | Introduction | |||||
| Half-band Nyquist decimation filter | By Quotes | None | 300 MHz | None | |
|
| This is a polyphase decimation filter that permits the down-sampling of an input signal by any power of 2. The filter core is organized as a highly optimized systolic array, allowing the user to specify very large decimation factors while keeping resource costs to a minimum. Input data is sampled on the rising clock-edge of clk when CLK_EN is active high. Internally, the samples are filtered and decimated then presented at the output interface, Y_OUT.The output signal EN_OUT is the output clock-enable signal that indicates when an output sample is valid. Application Decimation by a wide range of factors from 2 to 2N Reduction of input sample rate to make subsequent signal processing easier Decimation of signals after digital-down-conversion | Introduction | |||||
| SPI slave in mode 3 | 1000 Points | 256.000 Gates | 285 MHz | 130 nm | |
|
| The Serial Peripheral Interface (SPI) bus, established by Motorola, is a synchronous serial data link. It operates in master/slave and full duplex styles. That is, when a master device initiates a transaction and communicates with a certain slave device, they exchange data bit-by-bit. Furthermore, the single master communication is applied to the SPI bus. Thus, there is always a single master device (with one or more slave devices) on it.The SPI bus contains 4 wires, with each named SCK, MOSI, MISO and SS_n respectively. You may also find alternative naming conventions elsewhere. The following table lists their functions and directions:The typical SPI bus architecture is designed as follows:When the SPI master device wants to communicate with a certain slave device, it asserts the SS_n line of that slave device, and then exchange data using the MOSI and MISO lines based on the toggling SCK line.With clock polarity (CPOL) and clock phase (CPHA) set to different values, the SPI bus can operate in 4 modes. These modes are listed in the following table, where provide means that the communicating master and slave devices provide data on the MOSI and MISO lines respectively on the other hand, capture means that the communicating master and slave devices capture data on the MISO and MOSI lines respectively: | Introduction | |||||

| AES Codec with 128-bit datapath | 20000 Points | 22.000 K Gates | 260 MHz | 180 nm | |
|
| The IP core implements the NIST FIPS-197 Advanced Encryption Standard and can be programmed to either encrypt or decrypt 128-bit blocks of data using a 128-bit, 192-bit or 256-bit key. The IP has been carefully designed for high throughput applications with optimal logic resources utilization. The encryptor core accepts a 128-bit plaintext input word, and generates a corresponding 128-bit ciphertext output word using a supplied 128, 192, or 256-bit AES key. The decryptor core provides the reverse function, generating plaintext from supplied ciphertext, using the same AES key as was used for encryption. The hardware roundkey expansion logic has been designed as a discrete building block. This allows either to build a complete stand-alone AES solution, or to save logic resources by leaving the key generation process to the user. Alternatively, the roundkey expansion logic can be shared between multiple encryption/decryption cores for optimal silicon area resources utilization. The implementation is very low on latency, high speed with a simple interface for easy integration in SoC applications. | Introduction | |||||

|
| This JPEG Decoder IP core has been developed to be a complete standards compliant JPEG / MJPEG Hardware Decompressor / Decoder. When decoding JPEG images, pixel throughput can not be fixed for compressed JPEGs of arbitrary quality, as it depends on the compression ratio (bits needed to encode one pixel). To circumvent this limitation JPEG Decoder IP features a dual pixel component pipeline, allowing for greater decoding speeds. | Introduction | |||||
| Digital Down Converter with configurable Decimation Filter | By Quotes | None | 250 MHz | None | |
|
| DDC is a complex-valued digital down-converter with a configurable number of decimation stages. The design is ideal for high sample-rate applications and permits a digital input signal to be mixed- down and re-sampled at a lower data rate. The DDC is suitable for the down-conversion of any digitally modulated signal to baseband – an essential step before digital processing. The DDC features a high-precision 16-bit DDS oscillator for the digital mixing stage. This oscillator is fully programmable and offers excellent phase and frequency resolution. The digital mixing stage is a complex multiplier that allows the mixing of both real and imaginary (I/Q) inputs. If only real inputs are required, then the imaginary input (q_in) should be tied low. The output decimation stage features a configurable decimate-by-2N poly-phase filter for both I and Q channels. Each filter stage is highly optimized to use only 12 multipliers while still achieving 80 dB of stop-band attenuation. Application Compatible with any digital modulation scheme - e.g. QPSK, BPSK, QAM, WiMAX, WCDMA, COFDM etc. Conversion of IF signals to baseband frequencies for subsequent processing Digital I/Q Demodulators | Introduction | |||||
| Digital Video Scaler | By Quotes | None | 250 MHz | None | |
|
| The IP Core is a studio quality video scaler capable of generating interpolated output images from 16 x 16 up to 216 x 216 pixels in resolution. The architecture permits seamless scaling (either up or down) depending on the chosen scale factor. Internally, the scaler uses a 24-bit accumulator and a bank of polyphase FIR filters with 16 phases or interpolation points. All filter coefficients are programmable, allowing the user to define a wide range of filter characteristics. Pixels flow in and out of the video scaler in accordance with the valid-ready pipeline protocol. Pixels are transferred into the scaler on a rising clock-edge when pixin_val is high and pixin_rdy is high. As such, the pipeline protocol allows both input and output interfaces to be stalled independently. The scaler is partitioned into a horizontal scaling module in series with a vertical scaling module . Application Support for the latest generation video formats with resolutions of 4K and above Video scaling for flat panel displays, portable devices, video consoles, video format converters, set-top boxes, digital TV etc. Conversion of all standard and custom video resolutions such as HD720P to HD1080P, XGA to VGA etc. | Introduction | |||||
