Abstract: A command supply device supplies a command sequence that forms a loop. A loop command buffer accumulates a first partial command sequence. The first partial command sequence is a head part of a first command sequence repeatedly supplied to a CPU from among command sequences stored in a main memory, and is accumulated before the first command sequence is supplied to the CPU again. A linking command buffer accumulates a second partial command sequence. The second partial command sequence follows the first partial command sequence in the first command sequence, and is accumulated while the accumulated first partial command sequence in the loop command buffer is supplied to the CPU. A selection circuit supplies, to the CPU, a command from the accumulated second partial command sequence in the linking command buffer when the entirety of the first partial command sequence has been supplied to the CPU.

Abstract: A processor executes a program loop at high speed using a branch target information register instruction which is set immediately before the program loop and a high-speed loop instruction which is set at an end of the program loop. When the branch target information register instruction is decoded by an instruction decoder, code in a fetched instruction buffer is sent to a branch target instruction register, and a shifted pointer in a decoded instruction counter is sent to a branch target fetch address register. After the high-speed loop instruction has been decoded by the instruction decoder and a branch condition is satisfied, the pointer in the branch target fetch address register is sent to a fetched instruction counter and to the decoded instruction counter while the code in the branch target instruction register is sent to a decoded instruction buffer. By using the shifted pointer in the decoded instruction counter, the high-speed loop instruction can be efficiently executed with small-scale hardware.
