Heterogeneous computing system

Abstract

The invention discloses a heterogeneous computing system, which comprises a multi-layer storage space complex structural body. The memory of the heterogeneous computing system structurally comprises six memories including a global memory, a register, a local memory, a shared memory, a constant memory and a texture memory, wherein the global memory, the register and the local memory support a read / write operation, the constant memory and the texture memory have a write operation, and the memories have different structures, different operation speeds and different sizes and storage scales. Compared with the prior art, the heterogeneous computing system improves the efficiency of a CPU+GPU (Central Processing Unit Graphic Processing Unit) heterogeneous computing method.

Description

technical field [0001] The invention relates to the field of computer computing, in particular to a heterogeneous computing system. Background technique [0002] Heterogeneous computing mainly refers to the computing method that uses computing units of different types of instruction sets and architectures to form a system. Common computing unit categories include CPU, GPU and other coprocessors, DSP, ASIC, FPGA, etc. Heterogeneous computing has received more attention in recent years, mainly because the traditional method of increasing computing power by increasing the CPU clock frequency and the number of cores has encountered heat dissipation and energy consumption bottlenecks. At the same time, although dedicated computing units such as GPUs have low operating frequency, more cores and parallel computing capabilities, and the overall performance-chip area ratio and performance-power consumption ratio are high, they are far from being fully utilized. . In a broad sense,...
