Abstract
An apparatus and a method for writing bitwise data in a System On Chip (SOC) are provided. In the method, a master determines whether a size of data to be written on a slave is equal to or smaller than half of a size of data transmittable at a time. If it is determined that the data is equal to or smaller than half of the size of the data transmittable at a time, the master transmits the data to the slave via a bus. The master transmits a signal representing a bit at which the data is to be written via a bus lane not used for the data transmission.

A method for writing data on a bit basis in a System On Chip (SOC), the method comprising:
- determining, by a master, a size of write data with a size of data transmittable at a time;
- if it is determined that the size of the write data is equal to or smaller than half of the size of the data transmittable at a time, transmitting, by the master, the write data to a slave via some of data lanes via which data is transmitted to the slave;
- and
- transmitting, by the master, a bit selection signal representing a bit at which the write data is to be written to the slave via remaining data lanes not used for the write data transmission.
An apparatus for writing data on a bit basis in a System-On-Chip (SOC), the apparatus comprising:
- a master for determining a size of write data with a size of data transmittable at a time, for, if it is determined that the size of the write data is equal to or smaller than half of the size of the data transmittable at a time, outputting the write data via some of data lanes via which data is transmitted, and for outputting a bit selection signal representing a bit at which write data is to be written via remaining data lanes;
- and
- a slave for receiving write data and a bit selection signal from the master, and for processing the same.
