Embodiment Construction

[0043] figure 1 A part of a data processing device 2 for processing data is schematically shown. The device 2 has processing circuitry 4 capable of executing multiple parallel processing threads. The device 2 executes an instruction set comprising complex program instructions corresponding to a plurality of micro-operations to be executed by the processing circuit 4 . Examples of complex program instructions are load multiple or store multiple instructions for loading multiple values ​​from memory to registers of processing circuit 4 or storing multiple values ​​from registers of processing circuit 4 to memory . A load multiple / store multiple instruction may be decoded to generate multiple micro-ops, each micro-op for loading / store of one of multiple values. Another example of complex program instructions are instructions for performing relatively complex arithmetic operations, such as square root operations or floating point arithmetic operations. Complex arithmetic opera...

Abstract

A data processing apparatus 2 has processing circuitry 4 which can process multiple parallel threads of processing. A shared instruction decoder 30 decodes program instructions to generate micro-operations to be processed by the processing circuitry 4. The instructions include at least one complex instruction which has multiple micro-operations. Multiple fetch units 8 are provided for fetching the micro-operations generated by the decoder 30 for processing by the processing circuitry 4. Each fetch unit 8 is associated with at least one of the threads. The decoder 30 generates the micro-operations of a complex instruction individually in response to separate decode requests 24 triggered by a fetch unit 8, each decode request 24 identifying which micro-operation of the complex instruction is to be generated by the decoder 30 in response to the decode request 24.

Description

technical field [0001] The technology relates to the field of data processing. More particularly, the present technique relates to decoding program instructions to generate micro-operations in a data processing apparatus supporting parallel processing threads. Background technique [0002] Some instruction sets include complex program instructions corresponding to a plurality of micro-operations to be executed by the processing circuit, each micro-operation representing a portion of the operations associated with the program instruction. Accordingly, the instruction decoder may decode program instructions to generate micro-operations to be executed by the processing circuit. [0003] Some processing devices support multiple parallel processing threads. Separate fetch units may be provided for respective threads to trigger fetch micro-operations into the processing circuitry. A shared instruction decoder may be provided for generating the micro-ops required by the respecti...
