  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 can be tuned to the specific requirements of an embedded system or a partition. It is capable of doing aligned and MPU region allocations, and it has unique debug and self-healing features.

eheap will run on any embedded system, with or without an RTOS. A free evaluation library is available for those who want to try it on their systems (see below).

eheap Features

  • Multiple heap support for secure systems. New
  • Aligned allocations. New
  • ARM Cortex v7M MPU region allocations. New
  • Integral 8-byte and 12-byte block pools. New
