Abstract
A stack management unit includes a stack cache to accelerate data retrieval from a stack and data storage into the stack. The stack management unit also includes an address pipeline to transfer multiple data words by a spill control unit and a fill control unit in the stack management unit. The address pipeline contains an incrementor/decrementor circuit, a first address register and a second address register. An address multiplexer drives either the output signal of the incrementor/decrementor or a cache bottom pointer to the first address register. The output terminals of the first address register are coupled to the input terminals of the second address register. A stack cache multiplexer drives either the address in the first address register or the address in the second address register to the stack cache. A memory multiplexer drives either the address in the address multiplexer or in the first address register to a slow memory unit. The address in the second address register can be used to adjust the value of the cache bottom pointer.
