An apparatus for enqueuing kernels on a device-side is introduced to incorporate with at least a MXU (Memory Access Unit) and a CSP (Command Stream Processor): The CSP, after receiving a first command from the MXU, executes commands of a ring buffer, thereby enabling an EU (Execution Unit) to direct the MXU to allocate space of the ring buffer for a first hardware thread and subsequently write second commands of the first hardware thread into the allocated space of the ring buffer according to an instruction of a kernel.

Apparatuses for enqueuing kernels on a device-side

A method for computing trigonometric functions, performed by an ALU (Arithmetic Logic Unit) in coordination with an SFU (Special Function Unit), is introduced to contain at least the following steps. The ALU computes a remainder r and a reduction value x* corresponding to an input parameter x. The SFU computes an intermediate function f(x*) corresponding to the reduction value x*. The ALU computes a multiplication of the reduction value x* by the intermediate function f(x*) as the computation result of a trigonometric function.

A method for generating machine code for driving an execution unit is introduced to incorporate with at least the following steps: Data access instructions of a kernel, which are associated with the same memory surface, are collected. An address pattern associated with the data access instructions is analyzed to generate a global-id address. Machine code containing the global-id address is generated.
