Programmable hardware blocks for time-sharing arithmetic units using memory mapping of periodic functions

摘要

An apparatus relates generally to time sharing of an arithmetic unit. In such an apparatus, a controller is coupled to provide read pointers and write pointers. A memory block is coupled to receive the read pointers and the write pointers. A selection network is coupled to the memory block and the arithmetic unit. The memory block includes a write-data network, a read-data network, and memory banks.

1. An apparatus for time sharing of an arithmetic unit, comprising:
a controller coupled to provide read pointers and write pointers for a pattern representing a function; a memory block coupled to receive the read pointers and the write pointers; a selection network coupled to the memory block and the arithmetic unit; wherein the memory block comprises a write-data network, a read-data network, and memory banks; and the memory block configured to receive the read pointers and the write pointers to dynamically control the selection network for time multiplexing and context switching of the arithmetic unit for the pattern.
