A system and method for enabling a programmable device to execute instructions without interruption. An instruction space for storing instructions from a host application is bifurcated to define a program segment and a hold segment. At startup, instructions are loaded into the hold segment, and the programmable device begins executing those instructions. While the hold segment instructions are executed, the program segment is loaded with instructions. Once the program segment is filled, control is shifted to it and instructions from this segment are executed by the programmable device. When the program segment has been executed, control is shifted back to the hold segment, and instructions are taken from it while the program segment is reloaded with a fresh set of instructions from the host application. Once the program segment is reloaded, control is redirected and execution of instructions from the program segment is continued.

A programmable data filtering/searching system for use with a data network. The primary programmable hardware-based filtering and searching portions of the system are integrated onto the same printed circuit board as the data storage device to facilitate efficient filtering and searching of data from a data stream coming from a memory storage device after being captured. In addition, the actual hardware and software used to perform the filtering and searching routines is programmable such that various filter and search criteria can be entered and utilized. The data filtering/searching system also uses metadata in addition to the captured data to minimize the time required to perform certain processes on the data from the data stream.

An integrated data controller that utilizes a first-in first-out (FIFO) management system that compensates for the unpredictable nature of latency associated with requesting data from memory and enables the timing of data requests to be determined based on the number of pending requests and the amount of data currently residing in the buffer. The FIFO management system includes a FIFO controller and a FIFO buffer that monitor a credit value and a trigger value to determine when to make data request bursts upon a memory unit. The trigger value is an indication of whether there is a sufficient amount of free space for it to be beneficial to make a data request burst and the credit value is a number that indicates the number of a data blocks that should be requested in the data request burst.
