Abstract: A transmission apparatus includes a processor configured to: disable access to a third memory, store input first data in the first memory, generate second data based on the first data, store the second data in a second memory, and in a case where the second data exhibits abnormality, store, in the third memory, the first data stored in the first memory, enable a process of transmitting, perform the process of transmitting the second data stored in the second memory and transmitting the first data stored in the third memory, and exclusively enable access to the first memory and the process of the transmitting, and enable the access to the third memory in accordance with the abnormality.

Abstract: An intersection point is obtained between a triangle forming a 3-dimensional graphics and a straight line. In the straight line, a line in a triangle is obtained. Then, a pixel on the line is obtained, and only these pixels are read from memory for a drawing process. The straight line inside the triangle is determined using an edge functions.
