Configuration of a deep vector engine using an opcode table, control table, and datapath table

An integrated circuit device comprising:

• a compute channel including a plurality of computational circuit blocks coupled in series in a pipeline;
• a control table storing control entries corresponding to respective microoperations, each control entry including control flow information for branching to a next microoperation;
• a datapath table storing datapath configuration entries corresponding to respective microoperations, each datapath configuration entry including a plurality of computational circuit block configurations to configure the plurality of computational circuit blocks;
• an opcode table storing opcode entries corresponding to respective opcodes, each opcode entry including a pointer that is used to access the control table and the datapath table;
• an instruction decoder operable to:
• receive a machine instruction to perform a computation on an input tensor to generate an output tensor;
• decode the machine instruction to obtain an opcode;
• access the opcode table using the opcode from the machine instruction to obtain a pointer for a microoperation of the machine instruction;
• and
• use the pointer for the microoperation of the machine instruction to access a first control entry in the control table to obtain control flow information for the microoperation of the machine instruction, and access a datapath configuration entry in the datapath table to obtain a datapath configuration for the microoperation of the machine instruction;
• and
• a control logic circuit operable to:
• issue the microoperation of the machine instruction to the compute channel by configuring the compute channel with the first control entry and the datapath configuration for the microoperation of the machine instruction.
