3639 \index{FP\_ENTRIES}
3641 cache (of FP\_ENTRIES entries) which it uses to hold recent bases passed to ltc\_ecc\_mulmod(). Any base detected to be used twice is sent through the
3645 \index{FP\_LUT}
3646 The optimization uses a window on the multiplicand of FP\_LUT bits (default: 8, min: 2, max: 12), and this controls the memory/time trade-off. The larger the
3647 value the faster the algorithm will be but the more memory it will take. The memory usage is $3 \cdot 2^{FP\_LUT}$ integers which by default
3648 with TFM amounts to about 400kB of memory. Tuning TFM (by changing FP\_SIZE) can decrease the usage by a fair amount. Memory is only used by a cache entry
3649 if it is active. Both FP\_ENTRIES and FP\_LUT are definable on the command line if you wish to override them. For instance,
3656 \index{FP\_SIZE} \index{TFM} \index{tfm.h}
3657 would define a window of 6 bits and limit the cache to 8 entries. Generally, it is better to first tune TFM by adjusting FP\_SIZE (from tfm.h). It defaults
