Single-Rate Resource Sharing Architecture
How HDL Coder™ generates a single-rate architecture from a model to manage the execution of operations in the context of clock-rate pipelining and resource sharing. When you apply resource sharing to blocks in your design, HDL Coder decides the architecture to use based on the sample rate of the regions where sharing occurs. If resource sharing occurs in a region of the design that operates at the fastest base sample rate, then HDL Coder synthesizes a local multi-rate architecture, as described in Resource Sharing for Area Optimization. In this example, the shared resources are in a region that operates at a slower sample rate, so HDL Coder applies clock-rate pipelining and synthesizes a single-rate architecture.
Improve Resource Sharing with Design Modifications
Improve opportunities for resource sharing to optimize your model design by making certain modifications to your design. Resource sharing is an HDL Coder optimization that improves area utilization in the design on the target FPGA device. The optimization identifies multiple functionally equivalent resources and replaces them with a single resource. For more information, see Resource Sharing.
Improve Resource Sharing with Clone Detection and Replacement
Automatically identify and replace recurring patterns by using the 克隆件检测器 (Simulink Check) app. Consequently, it also improves opportunities for optimizing the model by using resource sharing. The Clone Detector app refactors models by identifying clones in a design and replacing clones with links to subsystem blocks in a library. This example uses a model that has already been modified for optimal resource sharing by using the Clone Detector app. To learn more about these modifications, see Improve Resource Sharing with Design Modifications.
