HighThroughput HDL Algorithms
DSP HDL Toolbox™ provides blocks to implement highbandwidth applications such as radar, SIGINT, and 5G FR2 wireless. To meet their bandwidth requirements, these applications need to process incoming data as multiple samples in parallel, or framebased processing. Framebased processing increases throughput by implementing the algorithm in parallel on each sample in the input vector. These implementations increase data throughput but use more hardware resources. The ports of blocks that support framebased processing accept column vector input and output signals. Each element of the vector represents a sample in time. Using framebased input can achieve gigasamplespersecond (GSPS) throughputs. These highthroughput rates are also referred to as supersample rates.
You can also find blocks that support framebased input and hardwareoptimized algorithms in Wireless HDL Toolbox™ libraries.
Blocks that Support FrameBased Input
Supported Block  Parameters to Enable Frame Input  Limitations 

FFT and IFFT  Connect a column vector to the input data port. The vector size must be a power of 2 between 1 and 64 and cannot be greater than the FFT length.  Framebased input is supported only when Architecture is set to Streaming Radix 2^2 . 
Channelizer and Channel Synthesizer  Connect a column vector to the input data port. The vector size must be a power of 2 between 1 and 64 and cannot be greater than the FFT length.  
Discrete FIR Filter  Connect a column vector to the input data port. The vector size must be less than or equal to 64.  You cannot use framebased input with the partly serial architecture. 
Biquad Filter  Connect a column vector to the input data port. The input vector size can be up to 64 samples, but large vector sizes can make the calculation of internal datatypes challenging. Vector sizes of up to 16 samples are practical for hardware implementation.  Vector input is supported only when you set Filter structure to Pipelined feedback form . 
FIR Decimator  Connect a column vector to the input data port. The vector size must be less than or equal to 64 samples. 

FIR Interpolator  Connect a column vector to the input data port. The vector size must be less than or equal to 64 samples.  You cannot use framebased input with Minimum number of cycles between valid input samples greater than 1. 
CIC Decimator  Connect a column vector to the input data port. The input vector size can be up to 64 samples.  Vector input is not supported with programmable decimation rate. 
CIC Interpolator  Connect a column vector to the input data port. The input vector size can be up to 64 samples.  Vector input is not supported with programmable interpolation rate. 
NCO  Set the Samples per frame parameter to the desired output vector size.  
Complex to MagnitudeAngle  Connect a column vector to the input data port. The input vector size can be up to 64 samples.
