Title: Innovations of Arun K Ghose
Introduction
Arun K Ghose is a notable inventor based in Hyde Park, NY (US). He has made significant contributions to the field of computing and electronics, holding a total of 3 patents. His work primarily focuses on enhancing the capabilities of central processing units and developing innovative oscillators.
Latest Patents
One of his latest patents is titled "Execution unit with an integrated vector operation capability." This invention integrates a vector operation capability into the execution unit (E-Unit) of a CPU, designed to support scalar instruction processing. The E-Unit features pipelined fixed point and floating point instruction functional units necessary for implementing the vector instruction set. Additionally, a set of vector registers is added to the architected data registers within the E-Unit. The control logic of the E-Unit is modified to queue and schedule both vector and scalar instructions, enhancing the load and store unit bandwidth capability to support the transfer of contiguous data blocks typically associated with vector processing. This integrated capability allows for improved processing of programs that include both vector and scalar type instructions.
Another significant patent is the "CMOS voltage controlled ring oscillator." This invention describes a variable frequency digital ring oscillator that can be formed in a compact area for chip testing. It employs a ring oscillator made of CMOS inverters, transmission gates, and capacitors, functioning as a voltage-controlled ring oscillator. The design achieves a wide range of oscillation frequencies with a minimal number of components. The oscillator frequency is controlled solely by DC voltages, which can be provided by a manufacturing chip tester. The output signal swings between Vdd and Vss without requiring additional level translation circuits to drive CMOS logic. The ring oscillator can consist of an odd number of CMOS inverters connected in cascade to form a loop, with a CMOS transmission gate inserted between each adjacent inverter.
