All operations, other than program-flow instructions, are performed as register operations in conjunction with seven addressing modes for source operand and four addressing modes for destination operand. The CPU is integrated with 16 registers that provide reduced instruction execution time. The register-to-register operation execution time is one cycle of the CPU clock. Four of the registers, R0 to R3, are dedicated as program counter, stack pointer, status register, and constant generator respectively. The remaining registers are general-purpose registers. Peripherals are connected to the CPU using data, address, and control buses and can be handled with all instructions. 4.2 Instruction Set The instruction set consists of 51 instructions with three formats and seven address modes. Each instruction can operate on word and byte data. Table 1 shows examples of the three types of instruction formats; Table 2 shows the address modes. Table 1. Instruction Word Formats INSTRUCTION FORMAT EXAMPLE OPERATION Dual operands, source-destination ADD R4,R5 R4 + R5 → R5 Single operands, destination only CALL R8 PC → (TOS), R8 → PC Relative jump, unconditional or conditional JNE Jump-on-equal bit = 0 |
