Multiport memory architecture is disclosed herein. An example memory includes an input port, a memory array, and an output port. The input port is coupled to receive data blocks and includes first and second buffers coupled to temporarily store alternate data blocks, and the output port is coupled to provide data blocks from the memory array. The memory array is partitioned into first and second partitions, with the first partition coupled to receive data blocks from the first buffer and the second partition coupled to receive data blocks from the second buffer, and the input port and the memory array are coupled to receive control signals to simultaneously receive a first data block at the first buffer, transfer a second data block from the second buffer to a first address in the second partition, and provide a third data block stored at a third address of the first partition.

Multiport memory architecture for simultaneous transfer

Techniques and mechanisms for circuitry to provide video data for loading to a buffer. In an embodiment, a loader circuit receives video data and determines MX data for a video frame and NZ data for the video frame, wherein M and N are different respective dimensions of a color space, and wherein X is a first encoding type and Z is a second encoding type. The first MX data includes data representing a first portion of a color component value, and the first NZ data includes data representing a second portion of that color component value. In another embodiment, the loader circuit sends the MX data via a first channel while sending the NZ data via a second channel to a random access buffer.
