Abstract
A new apparatus and method for securely distributing an application to processors of a processing unit. The processing unit is formed as part of an integrated circuit and comprises a plurality of processors (referred to as tiles), each having their own execution unit and storage for storing application data and additional executable instructions. The integrated circuit comprises a hardware module (referred to herein as the autoloader) that is configured to distribute a set of bootloader instructions (referred to herein as a secondary bootloader) to each of at least some of the tiles. Each of the tiles then executes instructions of the received secondary bootloader, which causes each tile to issue read requests to read a set of executable application instructions from a memory external to the integrated circuit. Each tile then performs operations using the received set of executable application instructions so as execute the application using the processing unit.
