Basic API Sample Introduction

Overview

This sample introduces the usage of Ascend C Basic API, including data movement, memory vector computation, Reg vector computation, matrix computation, resource management, synchronization control, atomic operations, TPipe/TQue, cache control, and utility APIs.

Sample List

Directory Name	Description
00_data_movement	This directory contains samples for multiple APIs related to data movement, demonstrating the usage of data movement interfaces.
01_memory_vector_compute	This sample directory uses operators such as reduce, sort, and transpose as examples to demonstrate the usage of memory vector computation interfaces.
02_reg_vector_compute	This directory contains samples for multiple APIs related to vector computation, implemented based on Reg programming interfaces.
03_matrix_compute	This sample directory uses operators such as batch_matmul to demonstrate the usage of matrix computation interfaces.
04_memory_management	This directory contains samples for multiple APIs related to resource management. Each sample is based on the Ascend C <<<>>> direct invocation method, supporting the implementation of both the main function and kernel function in the same cpp file.
05_sync_control	This directory contains samples for multiple APIs related to synchronization control. Each sample is based on the Ascend C <<<>>> direct invocation method, supporting the implementation of both the main function and kernel function in the same cpp file.
06_atomic	This directory contains samples for multiple APIs related to atomic operations. Each sample is based on the Ascend C <<<>>> direct invocation method, supporting the implementation of both the main function and kernel function in the same cpp file.
07_tpipe_tque	This directory contains samples for multiple APIs related to TPipe/TQue resource management. Each sample is based on the Ascend C <<<>>> direct invocation method, supporting the implementation of both the main function and kernel function in the same cpp file.
09_utils	This directory contains API samples related to utilities. Each sample is based on the Ascend C <<<>>> direct invocation method, supporting the implementation of both the main function and kernel function in the same cpp file.
10_cache_control	This directory contains samples related to cache control, introducing the usage of cache control APIs such as DataCachePreload and L2 Cache splitting, and demonstrating how to improve cache hit rate and reduce memory access latency by preloading data and adjusting data access order.
11_tool_interface	Detect positive/negative infinity in vector addition results using NumericLimits, Compare, and Compares.
