Title: Surendra Mandava: Innovator in Digital Signal Processing
Introduction
Surendra Mandava is a notable inventor based in San Jose, CA, who has made significant contributions to the field of digital signal processing. With a total of 2 patents to his name, Mandava has developed innovative solutions that enhance the efficiency and functionality of digital systems.
Latest Patents
One of Mandava's latest patents is titled "Multiprocessor System for Digital Signal Processing." This novel multi-DSP system allows a main DSP to operate concurrently with an auxiliary DSP for implementing a filter algorithm. The main DSP and auxiliary DSP have separate program memories but share the same data memory. The auxiliary DSP program memory is mapped to the main DSP program memory to allow the main DSP to download filter process instructions from its program memory into the auxiliary DSP program memory. The auxiliary DSP fetches the instructions from its program memory to execute them. An arbitration mechanism ensures that the auxiliary DSP can only access the shared data memory when the main DSP is not using it.
Another significant patent is "Selective Shadowing of Registers for Interrupt Processing." In this invention, interrupts are prioritized such that selected interrupts use shadow registers to save the current state of the machine, while other interrupts utilize a software-implemented interrupt service routine (ISR) to save and restore the current machine state. This innovation allows for a greater number of nested interrupts to be serviced without being limited by the depth of register shadowing.
