Abstract: A Java accelerator includes a hardware unit associated with the CPU portion, the hardware unit converting stack-based instructions, such as Java bytecodes, into register-based instructions such as the instructions which are native to the CPU. A thread lifetime unit in the hardware unit is used to maintain a count of the number of bytecodes to be executed while an active thread is loaded into the system. Once this count reaches zero or below, the operation of a/the thread in the system is stopped and the Java Virtual Machine loaded into the CPU portion in order to implement its thread manager. Additionally, a single step unit in the hardware unit allows the production of debugger indications after each stack-based instruction.

Abstract: A telephonic data communications system provides verbal communication of data in remote computer systems. The major components of the systems are a plurality of channels and a data processor. Each channel includes a text-to-speech translator for translating digitally stored textual data into analogue speech signals corresponding to the verbal expression of the textual data; a telephone interface for establishing a telephonic connection with a user by detecting incoming calls and by initiating calls; and an RS232 port for accessing a data base in a remote host computer system. The data processor includes software for controlling the communications protocols used by each channel, whereby each channel emulates a computer terminal suitable for communication with the remote computer system connected to that channel, and software for extracting selected data from the data received from the remote computer system.
