Datenabrufschaltung zum Abspielen von Musik

A music playing data fetch circuit for a personal computer which is capable of improving a music playing operation using a CPU of a personal computer by using a 64-bit FIFO memory without using an interrupt signal. The circuit includes a sound interface controller for receiving a serial playing data from a music playing program from a central processing unit (CPU) of a personal computer (PC), a midi (musical instrument device interface) interface controller for fetching a serial playing data from the sound interface controller and generating tone, waveform, etc. by enabling an interrupt request signal, and a buffer for buffering a data from the sound interface controller when the personal computer requests the data transmitted to the midi interface controller.
