A Finite Impulse Response (FIR) 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 particular, an efficient implementation for a general purpose processor having a substantial number of registers includes inner and outer loop code which together make memory accesses and KN multiply-accumulates, where L1 is the number of output vector elements computed during each pass through the outer loop and where L2 is the number of taps per output vector element computed during each pass through the inner loop. The efficient implementation exploits L1+2L2 general purpose registers. For an embodiment in which L1=L2=8, inner and outer loop code make memory accesses, which for filter implementations with large numbers of taps, approaches a 4x reduction in the number of memory accesses as compared to conventional methods.

The present invention provides an efficient method to implement nested if-then-else conditional statements in a SIMD processor, which requires only one vector compare instruction for both if and else parts of the conditional construct. No stack and stack-handling instructions are needed for vector condition codes. Two condition code flag bits representing if and else parts of testing per element provide for nesting of multiple if-then-else. All SIMD instructions are conditional including the vector compare instruction, and this provides a method for aggregating multiple conditions in nested if-then-else statements. M full levels of if-then-else nesting requires (2^M−1) nodes or vector test instructions and 2^M+1 condition code flags per vector element. Also, capability to compare any element of first source vector register with any element of second source vector is provided.

The present invention provides alignment and ordering of vector elements for SIMD processing. In the alignment of vector elements for SIMD processing, one vector is loaded from a memory unit into a first register and another vector is loaded from the memory unit into a second register. The first vector contains a first byte of an aligned vector to be generated. Then, a starting byte specifying the first byte of an aligned vector is determined. Next, a vector is extracted from the first register and the second register beginning from the first bit in the first byte of the first register continuing through the bits in the second register. Finally, the extracted vector is replicated into a third register such that the third register contains a plurality of elements aligned for SIMD processing. In the ordering of vector elements for SIMD processing, a first vector is loaded from a memory unit into a first register and a second vector is loaded from the memory unit into a second register. Then, a subset of elements are selected from the first register and the second register. The elements from the subset are then replicated into the elements in the third register in a particular order suitable for subsequent SIMD vector processing.
