TMS320C54x chip has a program bus, three data buses and four address buses. These three data buses (CB, DB and EB) connected to each unit within. Wherein, CB and DB bus transfer from the data memory read operand, EB bus transfer the data written to the memory. Parallel computing is the simultaneous use of D bus and E-bus. Wherein, D bus is used to perform arithmetic operation load or, E bus for storing the previous result. Parallel instruction with parallel load and multiply instructions, parallel load and store instructions, parallel storage and multiply instructions, as well as parallel storage and processing/subtract instruction four kinds. All instructions are single-word parallel single-cycle instructions. Parallel operation is stored when the result of the previous operation, and then be loaded or stored arithmetic. These commands are working in the accumulator high, and most parallel arithmetic instructions are protected by ASM (accumulator shift mode bits) affected.
