Abstract
An apparatus having a stack-top updating unit for processing an exchange instruction and a load instruction in parallel in a pipe-lined processor having a stack register file. Based on an information signal representing a modification of the stack-top after the current instruction is executed in a first pipe-line, a control signal indicating that a load instruction is executed by one of the first and second pipe-lines, and a second pipe-line enable signal, the stack-top updating unit generates a new stack-top signal and a current stack-top signal. The first pipe-line, in response to the current stack-top signal and operands, executes the operands, and the second pipe-line, in response to the new stack-top signal and the control signal, performs the load instruction or an exchange instruction. As a result, the load instruction or the Fload instruction can be simultaneously executed with another instruction or operand in the pipe-lined processor in an effective manner.
