 * For optimum performance, the default processor data cache size
 * settings here can be overridden by target-specific definitions
 * supplied at compile time.
 *
 * Line-by-line and CIA computations are blocked to fit in L1
 * cache.  If the cache size is set to 0, cache blocking is
 * turned off.
 *
 * For FFTs and FHTs, the L1 cache size setting controls the
 * point at which the computation switches over from recursive
 * to iterative.
 *
 * The L2 cache size is used for sizing internal benchmarks.
