Dynamic Memory Allocation in a VHDL Behavioural Synthesis System.
Full text not available from this repository.
VHDL is capable of describing the dynamic allocation of memory resources at ?run-time?. This paper describes how this concept may be supported in a hardware synthesis environment. This requires a heap management system to be synthesised and implicitly accessed from within any user code, supporting the use of the VHDL access type. A method for controlling the storage of dynamic information (the heap manager) is reviewed. Issues such as timing and fragmentation are also discussed. An example of a design synthesised using the methods shown is reviewed last, which demonstrates the power of the technique.
