Abstract: Certain aspects of the present disclosure provide techniques and apparatus for efficiently accessing memory in a computing system. An example method includes organizing a plurality of physical memory banks having a base size into a plurality of logical memory banks. A request to execute operations on the plurality of physical memory banks is received. The request to execute the operations comprises a request to interact with data having a sample width based on the base size. Responsive to receiving the request to execute the operations, the operations are executed on one or more logical memory banks of the plurality of logical memory banks via a memory crossbar shared across the plurality of logical memory banks. An amount of the data on which the operations are executed is a multiple of the sample width, and each logical memory bank has a size based on the base size and a multiplier value.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a receiving device may receive a wireless signal represented as a receive matrix. The wireless signal carries one or more information symbols modified through a wireless channel that is represented as a channel matrix. The receiving device may perform QR decomposition on the channel matrix to generate an upper triangular channel matrix. The receiving device may determine a selected demapping technique using the upper triangular channel matrix. The receiving device may perform the selected demapping technique on the receive matrix and the channel matrix. Numerous other aspects are described.
