  eheap™ — Embedded Heap




eheap is a bin-type heap that provides adaptability, safety, and high performance for embedded systems running on RTOSes or standalone. It is similar to dlmalloc, but designed for embedded systems. Unlike dlmalloc, eheap is not intended to be super-fast, but rather to be a good fit for the many requirements of embedded systems. Nonetheless, eheap is fast, and after being customized to your system, overall performance may actually be better than with dlmalloc. In addition, it offers some interesting debug and self-healing options. See eheap vs. dlmalloc for detailed information.
