Digital filter implementation suitable for execution, together with application code, on a same processor |
摘要 |
A filter is implemented in software on a general purpose processor in a manner which reduces the number of memory accesses as compared to conventional methods. In some realizations, both application code and filter code are executed on a same general purpose processor. The filter code incrementally loads respective portions of input and coefficient vector data from addressable storage into respective registers of the processor and performs successive operations thereupon to accumulate output vector data into other respective registers of the processor. The filter code typically exhibits an execution ratio of less than two input and coefficient data loads per operation to accumulate. In some realizations, the filter code is callable from the application code and provides the application code with a signal processing facility without use of a digital signal processor (DSP).
