Abstract: The disclosure defined by the invention described a stack caching system with a swapping mechanism for reducing software resource. The stack caching system utilizes a swap memory with higher access speed to increase the performance of the stack caching system. The stack caching system moves at least one first stack block which is the most frequently accessed stack block by the system from a first memory to the swap memory. Then, the stack caching system controls a pointer originally pointing to the first stack block to point to a corresponding address in the second memory. When the stack caching system accesses the first stack block, the stack caching system is directed to the second memory to access the first stack block.

Abstract: Stack caching systems and methods. A stack caching system comprises a first memory, a second memory, and a controller coupled between the first memory and the second memory. The controller identifies a first stack block from a plurality of stack blocks stored in the first memory, wherein the first stack block includes data contains at least one pointer; after the first stack block is identified, the controller moves the first stack block from the first memory to the second memory, and adjusts the pointer originally points to the first stack block to a new address in the second memory.

Abstract: Disclosed are a system and a method for increasing speed in executing a Java program. When an instruction is fetched and if the instruction can become a fast instruction, an IP is used to search a program section in a dynamic memory for determining the quick execution data, and the instruction is executed by referring to the quick execution data. If there is no quick execution data in the dynamic memory and the instruction is stored in a random access memory, the instruction is executed and quick execution data is added to the instruction. If there is no quick execution data in the dynamic memory and the instruction is stored in a static memory, the instruction is executed, the data of the dynamic memory is altered and quick execution data is added into the dynamic memory.
