Telecommunication device, more particularly, mobile radio terminal
First Claim
1. A telecommunication device comprising:
- a processor for processing data;
a memory which stores said data and is coupled to said processor by a data bus and an address bus;
a first address counter which provides an output address to said memory for reading out a desired data having said output address;
a count of said first address counter being changed to a current address each time said processor generates a desired address, said current address being provided to said memory as said output address;
wherein said first address counter is loaded with said desired address provided over said address bus when said current address differs from said desired address so that said output address is equal to said desired address.

Abstract
A telecommunication device has a processor for processing data and a memory which stores the data. The memory is coupled to the processor by a data bus and an address bus. A first address counter provides an output address to the memory for reading out a desired data having the output address. A count of the first address counter is changed to a current address in response to a control signal from the processor, each time the processor generates a desired address. The current address is provided to the memory as the output address which is also the desired address. A comparator compares the desired address with the output address from a second address counter and outputs a load signal to the first counter when the current address from the second address counter differs from the desired address. The load signal loads the desired address in the first counter over the address bus when the current address differs from the desired address so that the output address is equal to the desired address. If the current address equals the desired address, then the desired address is provided to the memory as the output address from the first address counter without use of the address bus.

9. A processing device comprising:
-
a processor for processing data and providing a desired address of a desired data; a memory which is coupled to said processor by a data bus; a first address counter which provides an output address to said memory for reading out said desired data having said output address; said output address being a count of said first address counter, said count being one of a changed count in response to a control signal from said processor which bypasses an address bus and a loaded count from said processor provided over said address bus when said changed count is different from said desired address. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. A method of reading data from a memory comprising:
-
providing a desired address of said data from a processor; changing a current address of a counter in response to a control signal from said processor each time said processor generates said desired address; loading said counter with said desired address provided from said processor over an address bus when said current address of said counter is different from said desired address, wherein said control signal from said processor bypasses said address bus; and providing said current address to said memory for reading said data. - View Dependent Claims (18)
