DEVICE AND METHOD FOR CONTROLLING SHARED MEMORY

Title:

DEVICE AND METHOD FOR CONTROLLING SHARED MEMORY

Document Type and Number:

Japanese Patent JP3454094

Kind Code:

B2

Abstract:

PROBLEM TO BE SOLVED: To provide a device and method for controlling shared memory by which efficient memory control can be realized by maintaining the memory access band widths per unit time required by band masters.
SOLUTION: A shared memory controller 103 decides the next memory cycle control before a current shared memory cycle ends by calculating and discriminating the memory access band widths of bus masters 100-102 at any time in the current shared memory cycle so that each bus master 100-102 may efficiently use a shared memory 104 by maintaining the minimum memory access band width required by each bus master 100-102.
