摘要

The present disclosure relates to a hardware accelerator for executing a computation task composed of a set of operations. The hardware accelerator comprises a controller and a set of computation units. Each computation unit of the set of computation units is configured to receive input data of an operation of the set of operations and to perform the operation, wherein the input data is represented with a distinct bit length associated with each computation unit. The controller is configured to receive the input data represented with a certain bit length of the bit lengths and to select one of the set of computation units that can deliver a valid result and that is associated with a bit length smaller than or equal to the certain bit length.

說明書

For example, the hardware accelerator 102 may comprise a FPGA. The host processor 103 and the FPGA may be configured so as to execute or implement the computation task. The host processor 103 may be coupled to a memory 105 storing a compiled software application 107. The compiled software application 107 includes function calls. The FPGA coupled to the hardware processor may include a compiled user function. The compiled user function may be executable in response to one of the function calls. The function call may comprise a message of variables that need to be processed by the user function. The hardware accelerator may be coupled to memories such as off-chip memories 111 and on-chip memories 112 for storing, for example, intermediate computation results of the hardware accelerator.
