Product Description

The AMD LogiCORE™ RAM-based Shift Register IP core generates fast, compact FIFO-like-style registers, delay lines or time-skew buffers using the SRL16/SRL32 mode of the slice LUTs available in AMD FPGA devices. Implementing Shift Registers with the SRL16/SRL32 provides large resource and power savings. The IP supports fixed-length or variable-length shift registers.

Key Features and Benefits

Generates fast, compact, FIFO-style shift registers or delay lines using the SRL16/SRL32 mode of the slice LUTs
User options to create fixed-length or variable-length shift registers
Speed or resource optimization for variable length shift registers
Optional output register with clock enable and synchronous controls for variable length shift registers
