摘要： A digital filter uses memory to emulate a variable shift register. Data samples are stored in a memory. The data samples are read from the memory, multiplied with corresponding coefficients stored in the same or a different memory, logically shifted, and written back into the memory so as to emulate a variable shift register. The data samples can be logically shifted by one or more bits at a time.

The engine also includes programmable interconnection logic coupled to the programmable filter elements for selectively combining, scaling, and accumulating output values from the first plurality of programmable filter elements and selectively providing accumulated values as inputs to the first plurality of programmable filter elements. A filter controller coupled to the programmable filter elements and the programmable interconnection logic includes its own microcode control program for external control of the programmable filter elements and the programmable interconnection logic. Multiple engines can be combined to form larger, more powerful engines.

摘要： A micro-programmable digital filter includes a plurality of programmable filter elements, an instruction memory for storing a control program, at least one instruction decoder for programming the filter elements based on the control program, and arithmetic logic for selectively scaling and accumulating output values received from the filter elements and providing accumulated values as inputs to the filter elements. The filter elements are typically coupled in series so that a coefficient output from one filter element can be passed to an adjacent filter element for implementing longer filters. A separate instruction decoder may be included for each filter element. Execution of the separate instruction decoders is typically staggered so that the instruction decoders can share the instruction memory and an accumulator without collision. Each filter element can be programmed to implement a different filtering function, or multiple filter elements can be programmed to operate on a single filtering function.
