A memory interface module provides interfacing between a host processor with multiple flash memories and parallel interfaces of varying protocols. The interface module includes multiple register files, multiple operation information registers, an internal memory, a flash interface portion, and a finite state machine (FSM). The register files receive a command from the host processor for controlling an operation of multiple flash memories. The operation information registers execute and store the command and operation information. The internal memory receives and stores host data from the host processor. The internal memory further stores flash data extracted from multiple flash memories. The flash interface portion interacts with the memory devices connected to the controller. The FSM extracts the command and the operation information from the register files, which are programmed by the user and controls the control signals of the memory devices connected to the controller through the flash interface.

An efficient implementation of DSP functions in a field programmable gate array (FPGA) using one or more computational blocks, each block having of a multiplier, an accumulator, and multiplexers. The structure implements most common DSP equations in a fast and a highly compact manner. A novel method for cascading these blocks with the help of dedicated DSP lines is provided, which leads to a very simple and proficient implementation of n-stage MAC operations.

A one bit full adder with sum and carry outputs performs independent functions. The full adder includes at least one look up table (LUT) for implementing a sum function, and at least one carry circuit for implementing a carry/borrow function. The carry circuit includes a first multiplexer having first and second inputs, a select line input, and a carry/borrow output. The carry circuit also includes an AND gate, an OR gate and an XOR gate. The AND gate has two inputs, and an output connected to the first input of the first multiplexer. The OR gate has two inputs, and an output connected to the second input of the first multiplexer. The XOR gate has a first input, and an output connected to the select line input of the first multiplexer. A second multiplexer has an output connected to the first input of the XOR gate. The at least one LUT and the at least one carry circuit provides independent sum and carry outputs for different function requirements.
