In that case the frame pointer is used to address the local variables, and all other stack frame content, with a constant offset. Fig. 1 shows a possible snapshot of a stack, holding subroutine arguments, return address, the previous frame pointer as well as saved registers and local ...
17. The method of claim 16, wherein the value is the address of the call of the subroutine plus one. Description: FIELD OF THE INVENTION The invention relates to operations in a microprocessor, and more specifically, to the use of a stack, in a microinstruction sequencer of a microprocesso...
An internal call/return stack (CRS) correction apparatus in a pipelined microprocessor is disclosed. Each time the microprocessor updates the CRS in response to a call or return ins
A RETURN STACK STRUCTURE AND A SUPERSCALAR MICROPROCESSOR EMPLOYING SAMEA return stack is described which stores return addresses associated with subroutine call instructions along with an ESP register value associated with the subroutine call instructions in a stack-type structure. During clock cycles ...
is a method for a microprocessor such that when a call is made to a subroutine or an interrupt, a return address is stored in a "stack" memory (RAM) and also that a particular piece of hardware write the return address to an additional register (latches) within the microprocessor. The...
Microprocessor for overlapping stack frame allocation with saving of subroutine data into stack areaWhen a subroutine call instruction is transferred from the instruction memory 39 to the IDB 29 and decoded by the decoder 18, the following operations (1)-(3) are executed in parallel: (1) a ...
A stack memory is contemplated for use with respect to subroutine parameter passing. The calling routine may perform multiple push commands to place parameters for use by the subroutine onto the stack. The subroutine may then access and modify the parameters upon the stack. Finally, the calling ...
While the start of a subroutine is usually its only point of entry, the start of a co-routine is the first point of entry and subsequent points of entry can follow yield commands. For example, like a subroutine, yielding in a co-routine can return the result and control to the calling...
subroutine call is needed, the subroutine call is implemented by calling a stack management routine. The stack management routine retrieves and stores a return address into a location in DRAM identified by a stack pointer, increments the stack pointer, and then executes a CALL instruction, causing...
