... OE CLK TO ALL REGISTERS High-Speed Image Filter with Coefficient RAM DESCRIPTION The LF3347 consists of an array of four 12 x 12-bit registered multipliers followed by two summers and a 32-bit accumulator. The LF3347 provides four 256 x 12-bit coefficient banks which are capable of storing 256 different sets of filter coefficients for the multiplier array ...

... Larger kernels or more complex functions can be realized by utilizing multiple devices. Unrestricted access to all data ports and addressable coefficient banks provides the LF3347 with considerable flexibility in applica- tions such as digital filters, adap- tive FIR filters, mixers, and other similar systems requiring high- speed processing ...

... DEVICES INCORPORATED FUNCTIONAL DESCRIPTION Coefficient Banks The LF3347 has four coefficient banks which feed coefficient values to the multipliers. Each bank can store 256 12-bit coefficients. In the example shown in Table 3, address 10 in coeffi- cient banks 1 through 4 is loaded with the following values: ABCH, 789H, 456H, 123H ...
