Compact code generation is very important for an embedded system that has to be implemented on a chip with a severely limited amount of size. Even though on-chip data memory optimization technique has been given more attention, on-chip instruction memory optimization should not be neglected. We propose in this paper some algorithms for a memory offset assignment for embedded DSP processors in o...

I introduce a partial differential equation to describe the process of prestack reflection data transformation in the offset, midpoint, and time coordinates. The equation is proved theoretically to provide correct kinematics and amplitudes on the transformed constant-offset sections. Solving an initial-value problem with the proposed equation leads to integral and frequency-domain offset contin...

In digital signal processors (DSPs) variables are accessed using k address registers. The problem of finding a memory layout, for a set of variables, that minimizes the address-computation overhead is known as the General Offset Assignment (GOA) Problem. The most common approach to this problem is to partition the set of variables into k partitions and to assign each partition to an address reg...
