    摘要: Circuits for a memory array and a method of operating a configurable memory block are disclosed. An embodiment of the disclosed memory circuits includes a first memory block coupled to a second memory block to form an array of memory blocks. Each of the memory blocks has multiple bit lines with a dedicated address decoder coupled to the bit lines from each of the memory blocks. Switches are placed in between the first and second memory blocks such that each of the bit lines from the first memory block is connected to a corresponding bitline from the second memory block through one of the switches. The switches may be used to either connect the second memory block to the first memory block or disconnect the second memory block from the first memory block.

    摘要: A delay circuit that includes a first delay cell oriented in a first orientation and a second delay cell oriented in a second orientation is described. In one embodiment, the first orientation is perpendicular to the second orientation. More specifically, in one embodiment, the first orientation is vertical and the second orientation is horizontal.

    摘要: In circuitry such as a programmable logic device (“PLD”), each of several multiplier blocks includes partial products generation circuitry and partial products addition circuitry. Two such multiplier blocks can be used together to provide multiply-accumulate (“MAC”) capability. The partial products addition circuitry in one of the paired blocks is used to add each successive product produced by the other paired block to a previous accumulation of products in the first-mentioned paired block. Provisions are also made for accumulating any overflow from operation of the partial products addition circuitry in the first-mentioned paired block.
