Abstract: In one example, an integrated circuit comprises: a memory configured to store a first mapping between a first opcode and first control information and a second mapping between the first opcode and second control information; a processing engine configured to perform processing operations based on the control information; and a controller configured to: at a first time, provide the first opcode to the memory to, based on the first mapping stored in the memory, fetch the first control information for the processing engine, to enable the processing engine to perform a first processing operation based on the first control information; and at a second time, provide the first opcode to the memory to, based on the second mapping stored in the memory, fetch the second control information for the processing engine, to enable the processing engine to perform a second processing operation based on the second control information.

Abstract: Methods and systems for performing hardware approximation of function are provided. In one example, a system comprises a controller, configurable arithmetic circuits, and a mapping table. The mapping table stores a first set of function parameters in a first mode of operation and stores a second set of function parameters in a second mode of operation. Depending on the mode of operation, the controller may configure the arithmetic circuits to compute a first approximation result of a function at an input value based on the first set of function parameters, or to compute a second approximation result of the function at the input value based on the second set of function parameters and to perform post-processing, such as quantization, of the second approximation result.

Abstract: Methods and systems for performing hardware computations of mathematical functions are provided. In one example, a system comprises a mapping table that maps each base value of a plurality of base values to parameters related to a mathematical function; a selection module configured to select, based on an input value, a first base value and first parameters mapped to the first base value in the mapping table; and arithmetic circuits configured to: receive, from the mapping table, the first base value and the first plurality of parameters; and compute, based on a relationship between the input value and the first base value, and based on the first parameters, an estimated output value of the mathematical function for the input value.

Abstract: A reconfigurable processing circuit and system are provided. The system allows a user to program machine-level instructions in order to reconfigure the way the circuit behaves, including by adding new operations. The system can include a profile access content-addressable memory (CAM) configured to receive an execution step value from a step counter. The execution step value can be incremented and/or reset by a step management logic. The profile access CAM can select an entry of a profile table based on an opcode and the execution step value, and the processing engine can execute microcode based on the selected entry of the profile table. The profile access CAM can translate the opcode to an internal short instruction identifier in order to select the entry of the profile table. The system can further include an instruction decoding module configured to merge multiple instruction fields into a single effective instruction field.
