Abstract
The present disclosure includes apparatuses and methods for operations using compressed and decompressed data. An example method includes receiving compressed data to a processing in memory (PIM) device and decompressing the compressed data on the PIM device.
Claims14
A method for operating a memory device, comprising:
- receiving, from a host external to the memory device, compressed data in a subsampled YUV image format by sensing circuitry of an intelligent frame buffer associated with a random access memory (RAM) array of memory cells on the memory device;
- configuring a sense amplifier and a compute component in the sensing circuitry for performance of a read operation on data stored by the array, a write operation on received data, and a decompression operation on the compressed data;
- decompressing the compressed data using the sense amplifier in the sensing circuitry on the memory device during the decompression operation until the compressed data is decompressed,
- wherein the decompressing of the compressed data comprises converting the subsampled YUV image format to a non-subsampled RGB image format in the sensing circuitry of the intelligent frame buffer and is performed without transferring data values involved in the decompression to a processing component external to the sensing circuitry;
- directing, by an operations component, the decompressing via bitwise performance of a number of logical operations by operating a plurality of compute components in the sensing circuitry as one-bit processing elements;
- storing an image in the non-subsampled RGB image format to the RAM array;
- compositing a plurality of images in the non-subsampled RGB image format into a different image using an alpha blending technique;
- and
- either displaying, rendering, projecting, or storing the different image.

An apparatus, comprising:
- a host external to a memory device, the host configured to send compressed data in a subsampled YUV image format;
- the memory device comprising circuitry configured to:
- receive the compressed data by sensing circuitry of an intelligent frame buffer associated with a random access memory (RAM) array of memory cells on the memory device,
- wherein a sense amplifier and a compute component in the sensing circuitry are configured to perform a read operation on data stored by the array, a write operation on received data, and a decompression operation on the compressed data;
- perform the decompression operation on the compressed data using the sense amplifier in the sensing circuitry on the memory device during the decompression operation until the compressed data is decompressed,
- wherein decompression of the compressed data comprises converting the subsampled YUV image format to a non-subsampled RGB image format in the sensing circuitry of the intelligent frame buffer, which is performed without transferring data values involved in the decompression to a processing component external to the sensing circuitry;
- direct, by an operations component, the decompression via bitwise performance of a number of logical operations by operating a plurality of compute components in the sensing circuitry as one-bit processing elements;
- store an image in the non-subsampled RGB image format to the RAM array;
- composite a plurality of images in the non-subsampled RGB image format into a different image using an alpha blending technique;
- and
- either display, render, project, or store the different image.
