The device can be configured to filter either as dimensionally separate (two ways; horizontal, then vertical or vertical, then horizontal) or as an orthogonal kernel (horizontal and vertical concurrently). During operation, both the horizontal and vertical filter sections can be independently held to facilitate resizing and other operations. The two (horizontal and vertical) 256-deep, independently programmable coefficient sets provide flexibility for many filter configurations. When combined with the 3K-deep onboard line buffers this brings the device to the next level of integration by reducing the need of fast, expensive external storage. 83 MHz Data Rate Seven 3K x 12-bit, Programmable Two-Mode Line Buffers 16 Horizontal and 8 Vertical Filter Taps 12-bit Data and Coefficients Embedded Memory for 256 Horizontal and Vertical Coefficient Sets Selectable 12-bit Data Output with User-Defined Rounding and Limiting Supports Dimensionally Separate Filtering and Orthogonal Kernels Allows Interleaved Data Streams for Multi-Channel Applications All 4,096 Coefficients can be Updated Within 27.7 µs Horizontal Filter Supports Decimation Up to 16 x 1 for Increasing Number of Filter Taps 3.3 Volt Power Supply 5 Volt Tolerant I/O 144-pin PQFP Package Industrial Temperature Available Note: Application notes and behavioral models available at www.logicdevices.com LF3310 Functional Block Diagram HCF11-0 ALU 13 HORIZONTAL LF INTERFACE HLD 12 VERTICAL LF INTERFACE VPAUSE VLD H Coef Bank 0 CONFIGURATION AND CONTROL REGISTERS H Coef Bank 1 B A ALU 13 B A ALU 13 B A ALU 13 B A ALU 13 B A ALU 13 B 1-16 1-16 1-16 1-16 1-16 1-16 A 12 HPAUSE VCF11-0 1-16 DIN11-0 1-16 DATA DELAY 12 E O I 1-16 1-16 1-16 1-16 1-16 1-16 1-16 DATA REVERSAL I/D REGISTERS TXFR A ALU 13 B A ALU 13 B 12 12 12 12 12 12 12 12 H Coef Bank 7 H Coef Bank 6 HCEN HCA7-0 8 H Coef Bank 2 VCEN VCA7-0 t H Coef Bank 3 8 25 V Coef Bank 7 V Coef Bank 6 V Coef Bank 5 25 V Coef Bank 4 25 25 25 25 27 25 H Coef Bank 5 H Coef Bank 4 25 27 tt 12 12 12 12 12 24 12 24 HACC 3K Line Buffer 32 26 3K Line Buffer 3K Line Buffer 3K Line Buffer 3K Line Buffer 12 24 12 24 12 24 12 24 DATA DELAY 3K Line Buffer 3K Line Buffer 24 12 24 12 12 12 32 "0" 32 26 12 "0" 32 VERTICAL ROUND SELECT LIMIT HORIZONTAL ROUND SELECT LIMIT 4 HRSL3-0 12 12 HSHEN V Coef Bank 0 V Coef Bank 1 V Coef Bank 2 V Coef Bank 3 VSHEN OE 4 CLK 2 VACC VRSL3-0 12 DOUT11-0 LF3311 Digital Image Filter DEVICES INCORPORATED Improved Description The LF3311 is an improved version of the LF3310 Horizontal/Vertical Digital Image Filter capable of operating at speeds of up to 111MHz. This improved speed will increase flexibility and performance. The added performance will enable you to use this device in more applications. For example, four interleaved data streams of 27MHz can now be processed within one device. The part is functionally identical to the LF3320 with the exception that the filter data path is specified to operate faster than the LF Control Interface. When operating the filter at speeds in excess of 90MHz, loading of coefficients via the LF Interface must be throttled to a maximum of 90MHz by asserting the PAUSE pin as required to allow sufficient setup time for the configuration data provided to the chip via the LF Interface.

The device is an 8-tap FIR filter with all required line buffers required contained on chip. Onboard memory stores up to 256 coefficients sets, which can all be updated within vertical blanking. 7 Line buffers can store video lines with lengths from 4 to 3076 pixels. Due to the length of line buffers, interleaved data can be fed directly into the device and filtered without separating the data into individual data streams. 83 MHz Data Rate Seven 3K x 12-bit, Programmable Two-Mode Line Buffers Cascadable for More Filter Taps Using the LF3347 12-bit Data and Coefficients Embedded Memory for 256 Coefficient Sets Selectable 16-bit Data Output with User-Defined Rounding and Limiting Allows Interleaved Data Streams for Multi-Channel Applications Separate Input Port for Odd and Even Field Filtering All 2,048 Coefficients can be Updated Within 27.7 µs 3.3 Volt Power Supply 5 Volt Tolerant I/O 100-pin PQFP Package Industrial Temperature Available Note: Application notes and behavioral models available at www.logicdevices.com LF3330 Functional Block Diagram CEN CA7-0 8 Coef Bank 7 Coef Bank 6 Coef Bank 5 4 SHEN 12 DIN11-0 OED RSL3-0 ACC Coef Bank 4 12 3K Line Buffer 12 12 12 12 24 12 24 12 24 12 24 26 3K Line Buffer VB11-0 12 3K Line Buffer 3K Line Buffer 12 24 12 24 12 24 26 3K Line Buffer 3K Line Buffer OEC COUT11-0 CF11-0 LD 12 12 12 12 12 LF INTERFACE PAUSE CLK CONFIGURATION AND CONTROL REGISTERS 6 12 Coef Bank 0 Coef Bank 1 Coef Bank 2 Coef Bank 3 16 16 DOUT15-0 t 24 12 LIMIT 32 ROUND t SELECT "0" 3K Line Buffer LF3347 High-Speed Image Filter with Coefficient RAM DEVICES INCORPORATED Features Description The LF3347 is a high speed FIR filter consisting of an array of four 12 x 12-bit multipliers followed by two summers and a 32-bit accumulator. Each multiplier array is provided with a 256 x 12-bit coefficient bank. All multiplier data inputs are user accessible and can be updated every clock cycle. The device is ideal for performing pixel interpolation in image manipulation and filtering applications. The LF3347 can perform a bilinear interpolation of an image (4 - pixel kernels) at real time video rates when used with an image resampling sequencer. Larger kernels or more complex functions can be realised by utilizing multiple devices. 83 MHz Data Input and Computation Rate Four 12 x 12-bit Multipliers with Individual Data and Coefficient Inputs Four 256 x 12-bit Coefficient Banks 32-bit Accumulator Selectable 16-bit Data Output with User-Defined Rounding and Limiting Two’s Complement Operands 3.3 Volt Power Supply 5 Volt Tolerant I/O 120-pin PQFP Package Industrial Temperature Available Note: Application notes and behavioral models available at www.logicdevices.com LF3347 Functional Block Diagram CC11-0 12 LF INTERFACE LD CCCLK ENBA A7-0 Coefficient Bank 1 (256 x 12-bit) 8 D111-0 Coefficient Bank 2 (256 x 12-bit) ENB1 12 D211-0 12 12 2 Coefficient Bank 3 (256 x 12-bit) ENB2 D311-0 12 12 2 ENB3 D411-0 12 ENB4 12 2 12 2 25 ACC Coefficient Bank 4 (256 x 12-bit) 25 3 SELRND3-0 4 32 SELLMT3-0 4 LMTEN 6 6 4 4 SHIFT4-0 5 5 5 Rounding Selecting Limiting Circuit 4 Rounding/ Limiting Registers 16 OCEN OE 16 CLK TO ALL REGISTERS S15-0 NOTE: NUMBERS IN REGISTERS INDICATE NUMBER OF PIPELINE DELAYS 7 LF3370 High-Definition Video Format Converter DEVICES INCORPORATED Decription The LF3370 is a video format converter capable of operating at HDTV data rates. This device converts to and from any of the various SDTV/HDTV digital video formats by utilizing an internal 3 x 3 Matrix Multiplier and two 1:2 Interpolation / 2:1 Decimation Half-Band Filters. Using the Input Demultiplexer and Output Multiplexer, the LF3370 can accept and output interleaved or noninterleaved video. For example, R/G/B/ Key data can be color space converted to Y/U/V/Key and down-converted to 4:2:2:4. By re-arranging the order of the functional sections, the opposite conversion can be achieved. The coefficients for the 3 x 3 Matrix Multiplier are fully user programmable to support a wide range of color space conversions.
