Semiconductor device, memory access control method, and semiconductor device system

摘要

In a semiconductor device in accordance with one embodiment, a memory access control unit counts the number of addresses accessed by burst access to each address included in an address set of an external memory that is going to be accessed. When the number of addresses is larger than a reference value, the memory access control unit performs burst access to the address, and when the number of addresses is smaller than the reference value, the memory access control unit performs random access to the address.

主权项

1. A semiconductor device comprising:
an operation circuit; and a memory access control unit that decides whether to perform burst access to an external memory or perform random access thereto based on an address set of the external memory that the operation circuit is going to access, wherein the memory access control unit
counts a number of addresses accessed by burst access to each address included in the address set, andperforms burst access to the address when the number of addresses is larger than a reference value, and performs random access to the address when the number of addresses is smaller than the reference value.
