摘要: Described is a programmable logic device (PLD) with columns of DSP slices that can be cascaded to create DSP circuits of varying size and complexity. Each DSP slice includes a plurality of operand input ports and a slice output port, all of which are programmably connected to general routing and logic resources. The operand ports receive operands for processing, and a slice output port conveys processed results. Each slice additionally includes a feedback port connected to the respective slice output port, to support accumulate functions in this embodiment, and a cascade input port connected to the output port of an upstream slice to support cascading.

摘要: Described is a programmable logic device (PLD) with columns of DSP slices that can be cascaded to create DSP circuits of varying size and complexity. Each slice includes a mode port that receives mode control signals for dynamically altering the function and connectivity of related slices. Such alterations can occur with or without reconfiguring the PLD.
