Estimating the term…
A programmable logic device is configured to accommodate multiplication by the provision in each logic region of specialized components to form and sum partial products. The specialized components are separate from the ordinary logic of the logic region, and their presence imposes little penalty on the performance of ordinary logic functions, while enhancing the speed at which multiplication is performed by minimizing the number of logic regions used for a particular multiplication operation, and also minimizing the use of the interconnection resources of the device to convey signals among those regions.
A programmable logic device comprising:
A programmable logic region for use in a programmable logic device, said programmable logic region comprising a plurality of input terminals and at least one output terminal, and being programmable to selectively perform any of a plurality of logic functions on input signals applied to the input terminals to produce an output signal applied to the output terminal, said region further having:
