... TO ALL REGISTERS (EXCEPT COEFFICIENT REGISTERS) Image Filter with Coefficient RAM Image Filter with Coefficient RAM DESCRIPTION The LF2247 consists of an array of four 11 x 10-bit registered multipliers followed by a summer and a 25-bit accumulator. The LF2247 provides a coefficient register file containing four 32 x 11-bit registers which are capable of storing 32 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 an addressable coefficient register file provides the LF2247 with consid- erable flexibility in applications such as digital filters, adaptive FIR filters, mixers, and other similar systems requiring high-speed processing. ...

... HIGH, data can not be shifted into the register file and the register file’s contents will not be changed. When enabling the coefficient register file for serial data input, the LF2247 requires a HIGH to LOW transition of SEN in order to function properly. Therefore, SEN needs to be set HIGH immedi- ately after power up to ensure proper operation of the serial input circuitry ...
